Determine the grams of sodium chloride produced when 10.0 g of sodium react with 10 g of chlorine gas according to the equation
2na + cl2 = 2nacl

Answer:

the correct answer: 2Ca3(PO4)2 + 6SiO2 -> P4O10 + 6CaSiO3

Explanation:

When the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster.

The rate of a reaction is how fast a chemical reaction occurs i.e. the conversion of reactants to products.

The rate of a chemical reaction can be influenced by certain factors including the concentration of reactants.

The more the concentration of a reactant, the more the collision between the reactants and hence, the faster the reaction will proceed.

Therefore, when the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster

The most basic answer to this is that the mitochondria generates energy for the cell's power needs.

But... (elaborated in explanation.)

Explanation:

As you may know, the mitochondria is the powerhouse of cells.

The mitochondria can ALSO identify cell death, and determine which cells (dead) must be destroyed.

The mitochondria helps regulate calcium storage, but quickly absorbing calcium ions until needed.

And lastly, the mitochondria can also help generate heat. A process called proton leak. This is known as non-shivering thermogenesis.

Answer:

506.81J

Explanation:

H = MC(T1 - T0)

H = 5 × 0.897 × (419 - 306)

H = 5 × 0.897 × 113

H = 506.81 J

As per specific heat of aluminium ,506.81 J of energy is gained  by the sample.

Specific heat capacity is defined as the amount of energy required to raise the temperature  of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.

It varies with temperature  and is different for each state of  matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.

It is given by the formula ,

Q=mcΔT

For the given example, Q=energy

m=mass=5 g, C=0.897 J/g.K

T₂=419 K

T₁=306 K

substituting in the formula ,Q=5×0.897(419-306)=506.81 J.

Thus, 506.81 J of energy is required.

Answer:

The removal of one or more electrons from a neutral atom results in a cation.

Explanation:

When you remove electrons from a neutral atom, the atom becomes more positive. Electrons have a negative charge and the protons inside of the nucleus have a positive charge. When electrons are removed, the positive charges from the protons outweigh the negative charges. This results in a positively charged atom, called a cation.

One of the most fascinating chemical experiments is the reaction between silver nitrate and copper wire in water. Characterised by fractal-like precipitates, this experiment is a stunning example of a simple redox reaction.

Copper reacting with silver nitrate is a chemical change. In a chemical change, new substances are formed with different chemical properties.

Copper (Cu) is a metal, and silver nitrate is a compound made of silver (Ag), nitrogen (N), and oxygen (O).When copper is added to silver nitrate, a reaction occurs. The copper atoms react with the silver nitrate molecules, resulting in the formation of new substances.

The reaction produces copper nitrate  and silver (Ag) as products.Copper nitrate is a compound formed by the combination of copper, nitrogen, and oxygen, while silver remains unchanged.

The color of the solution changes, indicating a chemical reaction has taken place. Copper nitrate is usually a blue-green color, while silver is a metallic silver color.The chemical properties of the substances involved in the reaction are altered. Copper, being a metal, is malleable and conducts electricity, whereas copper nitrate is a compound and does not possess these properties.

Answer:

C₂H₄O₂

Explanation:

To find the molecular formula of the organic acid, you need to (1) determine the mass of each element (from the given percents), then (2) convert grams of each element to moles (via atomic masses), then (3) find the empirical formula, and then (4) find the molecular formula.

(Step 1)

39.9% C -----> 39.9 g C

6.7% H -----> 6.7 g H

53.4% O -----> 53.4 g O

(Step 2)

Atomic Mass (C): 12.011 g/mol

Atomic Mass (H): 1.008 g/mol

Atomic Mass (O): 15.988 g/mol

39.9 grams C             1 mole
----------------------  x  ----------------------  = 3.32 moles C
                                12.011 grams

6.7 grams H              1 mole
--------------------  x  ---------------------  =  6.65 moles H
                              1.008 grams

53.4 grams O              1 mole
----------------------  x  ----------------------  =  3.34 moles O
                                15.998 grams

(Step 3)

The empirical formula is made up of the lowest possible amount of each element in the molecule. These amounts can be found by dividing the molar value of each element by the smallest molar value. In this case, the smallest molar value is 3.32 moles C. The calculated values make up the subscripts in the empirical formula.

3.32 moles C / 3.32  =  1 mole C

6.65 moles H / 3.32  =  2 moles H

3.34 moles O / 3.32  =  1 mole O

Empirical Formula: CH₂O

(Step 4)

To find the molecular formula, you first need to determine the molar mass of the empirical formula. Once you have this value, you need to determine how much you need to scale the formula up by. In this case, the molar mass of the empirical formula is half of the molar mass of the molecular formula. Therefore, you need to multiply the amount of each element in the molecule by 2.

Molar Mass (CH₂O): 12.011 g/mol + 2(1.008 g/mol) + 15.998 g/mol

Molar Mass (CH₂O): 30.025 g/mol

30.025 g/mol x 2 = 60.05 g/mol

CH₂O x 2 = C₂H₄O₂

Considering the definition of chemical compounds, a group of atoms of more than one elements forms chemical compounds.

Chemical Compounds are substances that are made up of a minimum of 2 elements that have reacted with each other to give another substance different from the initial elements. Elements are held together by what is known as a chemical bond.

In other words, a chemical compound is any substance formed by the union of two or more types of chemical elements, that is, by atoms of two or more different types of chemical elements, joined together by chemical bonds in certain proportions.
