when temperature and pressure are held constant, volumes can be used in gas-phase reaction stoichiometry because

Answers

Answer 1

Because of Avogardo Hypothesis, volumes can be used in gas phase reaction stoichiometry at constant temperature and pressure.

Avogadro's Law (also known as Avogadro's Hypothesis or Avogadro's Principle) is an experimental gas law that relates the volume of gas to the amount of gaseous matter present.

Avogadro's law states that "equal volumes of all gases at the same temperature and pressure have the same number of molecules". At constant temperature and pressure, (mol) of a gas is directly proportional.

For example, if two ideal gases, hydrogen and nitrogen, are mixed in equal amounts, they contain the same amount of molecules. This only happens if they are kept at the same pressure and temperature. This shows the ideal behavior of gases.

Let's look at this law mathematically: the overall law can be written as

V is directly proportional to n

or V = nK , K (a constant)

Amount of gas; “n” is the gaseous substance measured in moles. "k" is a constant defined for a specific pressure and temperature.

Comparing the same gas under different conditions, the law is : V₁/ n₁=V₂/ n₂

The equation shows that the number of moles of gas increases in proportion to the increase in gas volume. Therefore, the total number of atoms or molecules present in a given volume of gas is completely independent of the molar mass or size of the gas.

onsidering that the naoh should be within a few percent of 0.30 m, what volume (in ml) would you expect to use for your third trial with 2.0453 g of khp?

Answers

The volume (in ml) would we expect to use for our third trial with 2.0453 g of KHP will be 33.0 ml

Molarity of NaOH = 0.30 molar

Mass of KHP = 2.0353 G

Molar mass of KHP = 204.2 g/mol

Volume of NaOH = ?

First we will find out the number moles of KHP

number of moles = mass / molar mass

number of moles of KHP = 2.0453 g / 204.2 g/mol

number of moles of KHP = 0.010 mol

Now we will find out the volume of NaOH

volume = number of moles / molarity

volume of NaOH = 0.010 mol / 0.30 M

volume of NaOH = 0.033 L

Conver L to ml

volume of NaOH = 0.33 L * 1000

Rose petals contain a variety of different coloured pigments. A student wants to identify these pigments. Explain why

Answers

The petal of rose has different kinds of pigments like anthocyanins, carotenoids which give them the colors.

What are Anthocyanins?

Anthocyanins are the pigment that produces red color in the roses. They belong to Flavonoids family.

The pigments in a rose's petals give it its color. These pigments mostly consist of carotenoids and anthocyanins. Bright yellow, orange, and red pigments like those in lemons, oranges, and tomatoes are made by carotenoids. They are contained in structures called plastids, which are a component of the cytoplasm of plant cells. They are therefore steady and largely unaffected by the environment or the health of the plant. Deep red, magenta, purple, and blue colors are made of anthocyanins. They are transported via the sap of the plant and are water soluble. They are far less stable and more susceptible to external variables because they are in a fluid environment.

According to research, a bloom's anthocyanin content and sap pH fluctuate as a flower develops from a bud to a bloom. The pH of the sap increases with bloom aging and anthocyanin content decreases. As those who grow hydrangeas are aware, more acidic conditions prefer the pink/red end of the color spectrum while high alkaline levels produce blue colorations. As a result, as your rose bloom ages and its pH rises, the red will tend to lean toward the darker, bluer side of the spectrum. When a flower is in bloom, anthocyanin levels are still high, but they start to drop off swiftly as the blossom fades.

Answers

the mole fraction of the total ions in an aqueous solution prepared by dissolving 0.400 moles of caf2 in 850.0 g of water. is 0.00840 moles

The calculation of the mole fraction is as follow:

As we know that

Molar mass = Number of grams ÷ number of moles

Or

number of moles = Number of grams ÷ molar mass

from the question

Number of moles of CaI2 = 0.400

And, Molar mass of water = 18.0 g/mol

Now we can calculate  the  moles of water is

= 850.0 g ÷ 18.0 g/mol

= 47.22 mol

And, Total number of moles is

= 0.400 + 47.22

= 47.62

So, Mole fraction of CaI2 is

= 0.400 ÷ 47.62

= 0.00840 mole

hence, the mole fraction of the total ions in an aqueous solution prepared by dissolving 0.400 moles of caf2 in 850.0 g of water. is 0.00840 moles

Ammonia is a colorless gas which when dissolved in water readily gives ammonium hydroxide which causes irritation. It can also be used as cleaning agent also it is a pungent gas composed of hydrogen and nitrogen.

According to the given equation of ammonia formation,

N2 + 3H2 -------> 2NH3

Answers

The root mean square speed of O₂ gas molecules under the same conditions is 521.04ms⁻²

Kinetic energy is the energy an object has because of its motion

Here given data is

He gas = 6950 j/mol

We have to find root mean square = ?

So the formula is to find root mean square is

Vrms = √RT/m

Vrms = RMS velocity of the gas

T = absolute temprature of the gas

M = molar mass of the gas

R = universal gas constant

So, average molar kinetic energy of gas

E = 1/2 mv²rms = 1/2 RT

This equation reveal that molar KE is independent of the nature of the gas and it only depends on temprature as ideal behavior is concerned and so both He and O₂ will have same KE = 6950 j/mol and under the same condition of temprature

So for O₂

1/2 m O₂ V²rmsO₂ = 6950 j/mol

Taking atomic mass of O₂ = 16g/mol

V²rmsO₂ = 6950 × 2/2×16g/mol

VrmsO₂ = √69500000/16g/mol

VrmsO₂ = 521.04ms⁻²

How many protons, electrons, and neutrons?

Number of protons

= atomic number

= 55

Number of electrons

= atomic number - ion
