What mass of ammonium sulfate, (NH4)2SO4 must be added to prepare
200.0 g of a 3.5% solution of ammonium sulfate in water?

Answers

Considering the definition of percentage by mass,  the mass of ammonium sulfate that must be added to prepare 200.0 g of a 3.5% solution of ammonium sulfate in water is 7 g.

Percentage by mass

The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.

In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.

The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

[tex]percent by mass=\frac{mass of solute}{mass of solution}x100[/tex]

Mass of ammonium sulfate

In this case, you know:

mass of ammonium sulfate= ?mass of solution= 200 gpercent by mass= 3.5 %

Replacing in the definition of percent by mass:

[tex]3.5 =\frac{mass of ammonium sulfate}{200 g}x100[/tex]

Solving:

3.5÷100= [tex]\frac{mass of ammonium sulfate}{200 g}[/tex]

0.035= [tex]\frac{mass of ammonium sulfate}{200 g}[/tex]

0.035×200 g= mass of ammonium sulfate

7 g= mass of ammonium sulfate

Finally, the mass of ammonium sulfate that must be added to prepare 200.0 g of a 3.5% solution of ammonium sulfate in water is 7 g.

If I have an unknown quantity of gas at a pressure of 3.85 atm, a volume of 32.4 liters, and a temperature of
80.4°C, how many moles of gas do I have?

Answers

Answer:

4.30 moles

Explanation:

You need to use the Ideal Gas Law. The equation looks like this:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

Before you can plug the given values into the equation and simplify to find "n", you need to convert Celsius to Kelvin. The final answer should have 3 sig figs to match the sig figs of the given values.

P = 3.85 atm                        R = 0.08206 atm*L/mol*K

V = 32.4 L                            T = 80.4 °C + 273.15 = 353.55 K

n = ? moles

PV = nRT

(3.85 atm)(32.4 L) = n(0.08206 atm*L/mol*K)(353.55 K)

124.74 = n(29.012313)

4.30 = n

Answers

Answer:

Bromine

Explanation:

To identify the gas, you first need to find the moles of the gas. You can do this using the Ideal Gas Law:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas Constant (0.08206 atm*L/mol *K)

-----> T = temperature (K)

After converting mL to L and Celsius to Kelvin, you can plug the values into the equation and simplify to find the moles.

P = 1.98 atm                                            R = 0.08206 atm*L/mol *K

V = 752 mL / 1,000 = 0.752 L                T = 62 °C + 273.15 = 335.15 K

n = ? moles

PV = nRT

(1.98 atm)(0.752 L) = n(0.08206 atm*L/mol *K)(335.15 K)

1.48896 = n(27.5024)

0.0541 = n

You can identify the gas by determining the molar mass of the gas, which is specific to each element. The molar mass exists as a ratio that compares the mass per 1 mole.

Molar Mass = mass / moles

Molar Mass = 4.32 g / 0.0541 moles

Molar Mass = 79.8 g/mol

This molar mass is closest to the molar mass of bromine (79.904 g/mol).

What classifies a substance as an element?

What classifies a substance as a compound?

Answers

An element is a substance that cannot be broken down by chemical means. Elements are extremely particular compounds that serve as the foundation for all life and matter (well other than the stuff smaller than atoms). It can contain one atom or trillions of them for anything to be an element, however atoms of different types cannot be combined in. That is to say, every atom has a set number of protons, ranging from 1 to 118. You can be positive that the substance you have is hydrogen if there is just one proton present. Mercury is what you get if you have 80 protons. Atoms of pure hydrogen only contain one proton. As most people are aware, if you add oxygen to it, it turns into water, which is no longer an element but a compound. Nevertheless, the building blocks are the elements. Every single object you can see is composed of elements, whether there are many of them, as there are in the human body, or only a few, as there are in salt.

A compound is a substance with a definite composition (with some leeway there, there are 'non-stoichiometric' compounds), that is composed of 2 or more elements.

Further explanation:

A compound in chemistry is a material that is created by mixing two or more distinct chemical elements in such a way that the atoms of the various elements are kept together by strong chemical bonds. These bonds form as a result of the sharing or exchange of electron s among the atoms. A molecule is the smallest, unbreakable unit of a substance.

A mixture is not a compound since there is no bonding between the atoms of the constituent substances in a mixture. In certain cases, mixing dissimilar elements causes chemical reactions that result in the formation of bonds between the atoms and the molecules of a compound. Other possibilities allow mixing distinct components without causing a reaction, preserving the separate identities of the elements. When elements are combined, reactions can happen quickly or slowly (for example, when iron is exposed to oxygen) (as when lithium is exposed to oxygen). There are times when an element is introduced to a chemical, a reaction takes place, creating new compounds (as when pure elemental sodium is immersed in liquid water).

A compound frequently looks and acts quite different from any of the constituent parts. Think about hydrogen (H) and oxygen, for instance (O). At standard atmospheric pressure and room temperature, both of these substances are gases. However, they combine to form the well-known material known as water, which is a liquid at room temperature and at normal atmospheric pressure and whose molecules each contain two hydrogen atoms and one oxygen atom (H2O).

Few elements' atoms readily combine with those of other elements to produce compounds. These gases—helium, neon, argon, krypton, xenon, and radon—are referred to as noble or inert gases. Compounds made of certain elements can be formed easily with other elements. Examples include fluorine, chlorine, and oxygen.

2) The adjective compound refers to something that is made up of several different components. Examples of this usage include compound eyes, which are found in a variety of insects, compound microscopes, which are high-power magnifying devices made up of multiple lenses, compound sentences, which are organized collections of smaller sentences that form a single integrated perceptual environment, and compound documents.

QUESTION 3
List the two ways of determining the chloride content of water

Answers

After removing the particles, the solution's chloride content can be assessed using various techniques, such as titration and photometry.

What is the importance of chloride determination?One of the most prevalent inorganic anions in water and wastewater is chloride, which forms the chloride (Cl-) ion. Sodium chloride, a specific food item that passes through the digestive tract undigested, has a higher chloride concentration in wastewater than in raw water. Due to salt water leaking into the sewage system, coast chloride may be present in high concentrations along the sea. Additionally, industrial processes may cause it to rise.The salty taste caused by chloride concentration in drinkable water varies and depends on the water's chemical makeup. If sodium cation is present, some waters with 250 mg/L Cl- may have a flavor that can be identified as salty. On the other hand, when calcium and magnesium cations predominate, the typical salty taste may be missing in fluids containing as much as 1000 mg/L. A high chloride level may injure developing plants, steel pipelines, and structures.The salinity of various water sources can be determined using the detected chloride ions. It is a crucial parameter for brackish water (or seawater or industrial brine solution) because it indicates how much desalting of the apparatus is needed. Additionally, it affects the COD calculation, necessitating a modification based on the amount present or adding a complexing agent like HgSO4. Additionally, column studies that predict the fate of various pollutants in soil and liquid media use chloride ions as tracer ions.

Answers

Considering the Hess's Law, the enthalpy change for the reaction is 68 kJ/mol.

Hess's Law

Hess's Law indicates that the enthalpy change in a chemical reaction will be the same whether it occurs in a single stage or in several stages. That is, the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.

Enthalpy of reaction of nitrogen dioxide

In this case you want to calculate the enthalpy change of:

N₂ + 2 O₂ → 2 NO₂

which occurs in two stages.

You know the following reactions, with their corresponding enthalpies:

Equation 1: N₂ + O₂ → 2 NO     ΔH = 180 kJ/mol

Equation 2: 2 NO + O₂ → 2 NO₂     ΔH = –112 kJ/mol

Because of the way formation reactions are defined, any chemical reaction can be written as a combination of formation reactions, some going forward and some going back.

In this case, first, to obtain the enthalpy of the desired chemical reaction you need one mole of N₂ on reactant side and it is present in first equation so let's write this as such.

In the same way, you need two moles of NO₂ on product side and it is present in second equation so let's write this as such.

Finally, in this way the two moles of NO cancel.

Then, it is not necessary to modify the given equations. So, adding or canceling the reactants and products as appropriate, and adding the enthalpies algebraically, you obtain:

N₂ + 2 O₂ → 2 NO₂     ΔH= 68 kJ/mol

Finally, the enthalpy change for the reaction is 68 kJ/mol.

The molar mass of NaHCO3
is 84.01 g/mol
and the molar mass of CO2
is 44.01 g/mol.
What is the percent by mass of NaHCO3
in the original mixture?

Answers

Answer: 63.75 %

Explanation:

The balanced chemical equation for this reaction is:

NaHCO3 + HA = NaA + H2O + CO2

According to the chemical equation, one mole of NaHCO3 will react with one mole of HA to form one mole of NaA, H2O and CO2. All the components are in same mole ratio of 1:1:1:1

So,

Moles of CO2 = weight/molar mass = 0.561/44 = 0.01275 moles

Moles of CO2 will be equal to moles of NaHCO3 = 0.01275 moles

Moles = weight/mass

Weight = moles × mass

So the weight of NaHCO3 = 0.01275 × 84.01 = 1.071 g

The percentage mass of NaHCO3 in the original mixture =(1.071/1.68)× 100% = 63.75 %

Therefore, the percent by mass of NaHCO3 in the original mixture was 63.75 %

What does h20 mean on the periodic elements chart

Answers

Answer:

The compound, H₂O, will not be found on the periodic table. This is because the periodic table only consists of individual elements. That being said, the elements found within H₂O are located on the periodic table. H₂O consists of hydrogen, denoted by the symbol "H", and oxygen, denoted by the symbol "O". The subscript (the 2) tells us that there are 2 hydrogen atoms located in the H₂O molecule.

Hydrogen is the first element listed on the periodic table and can be found in the top leftmost position. Oxygen is the eighth element on the periodic able and is located in the second row at the top right.

What would the pH of a solution that had a hydroxide ion concentration of 1 x 10-2 M be?

Answers

Taking into account the definition of pH and pOH, the pH of the solution is 12.

Definition of pH

pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:

pH= - log [H⁺]= - log [H₃O⁺]

Definition of pOH

Similarly, pOH is a measure of hydroxyl ions in a solution and is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:

pOH= - log [OH⁻]

Relationship between pH and pOH

The following relationship can be established between pH and pOH:

pOH + pH= 14

pH in this case

A solution had a hydroxide ion concentration of 1×10⁻² M. In other words [OH⁻]= 1×10⁻² M.

Replacing in the definition of pOH, it is calculated as:

pOH= - log (1×10⁻² M)

Solving;

pOH= 2

Replacing in the relationship established between pH and pOH, the pH can be calculated as:

pH + 2= 14

Solving:

pH= 14 - 2

pH= 12

In summary, the pH of the solution is 12.
