Answer is D
Explanation: A gamma ray primarily consists of pure energy and no mass.
Answer : The partial pressure of
and
is, 216.5 mmHg and 649.5 mmHg
Explanation :
According to the Dalton's Law, the partial pressure exerted by component 'i' in a gas mixture is equal to the product of the mole fraction of the component and the total pressure.
Formula used :


So,

where,
= partial pressure of gas
= mole fraction of gas
= total pressure of gas
= moles of gas
= total moles of gas
The balanced decomposition of ammonia reaction will be:

Now we have to determine the partial pressure of
and 

Given:


and,

Given:


Thus, the partial pressure of
and
is, 216.5 mmHg and 649.5 mmHg
