Answer:
d. inversely proportional to the volume of its container.
Explanation:
Boyle's law states that at constant temperature and number of moles, the pressure of the gas is inversely proportional to the volume of the gas.
Thus, P ∝ T
P is the pressure
T is the temperature
For two gases at same temperature, the law can be written as:-

<u>Thus, according to the question, the answer is:- d. inversely proportional to the volume of its container.</u>
A mixture consists of numerous substances, whereas a substance does not consist of mixtures, but rather of compounds. Mixtures can be separated physically, while substances cannot.
The correct answer is 30 seconds
When a single compound breaks down into two or more compounds or elements in a chemical reaction then it is known as decomposition reaction.
The chemical symbol for sodium carbonate is
.
The decomposition of sodium carbonate is:

The decomposition of sodium bicarbonate,
will result in the formation of sodium oxide,
and carbon dioxide,
.
Hence, carbon dioxide,
will produce with sodium oxide,
on decomposition of
.
