Explanation:

A property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, change in shape, size, mass, volume, density, solubility etc are all physical properties.

So, when we crush a large sample of solid calcium sulfate into smaller pieces for testing then their density and solubility will remain the same. But their size and shape will definitely change.

As density is the mass divided by volume. Total mass of solid calcium sulfate is not changed during the testing. Hence, it will remain the same in a given volume.

Thus, we can conclude that two physical properties are the same for both the large sample and one of the smaller pieces is that their solubility and density.

Answer:

Initial rate of reaction is 2.07\times 10^{-3}M.s^{-1}.

Explanation:

It is a second order reaction.

Initial rate of reaction = k[O_{3}]_{0}[NO]_{0}   , where k is rate constant, [O_{3}]_{0} is the initial concentration of O_{3} and [NO]_{0} is the initial concentration of NO.

Here, k = 4.09\times 10^{6}M^{-1}.s^{-1}, [O_{3}]_{0}=5.84\times 10^{-6}M and [NO]_{0}=8.65\times 10^{-5}M

So, initial rate of reaction = (4.09\times 10^{6}M^{-1}.s^{-1})\times (5.84\times 10^{-6}M)\times (8.65\times 10^{-5}M)

= 2.07\times 10^{-3}M.s^{-1}

So, initial rate of reaction is 2.07\times 10^{-3}M.s^{-1}

Answer: In the reaction:

a) The reactants are: P

b) The products are: M and N

Explanation:

The given reaction equation is as follows.

P \rightarrow M + N

Reactants are the species present on the left side on an arrow in a chemical reaction equation.

On the other hand, products are the species which are present on the right side of an arrow in a chemical reaction equation.

Hence, in the given reaction equation P is the reactant. Whereas M and N are the products.

Thus, we can conclude that in the reaction:

a) The reactants are: P

b) The products are: M and N
