Explanation: that what I trying to remember
Answer:
The correct answer is: X is nitrogen dioxide, and Y is a metal oxide
Explanation:
Combustion of compound of containing nitrogen and metal will give nitrogen dioxide and metal oxide as product. During combustion reaction a compound reacts with oxygen in order to yield oxides of elements present in the compound.
The general equation is given as:

Hence, the correct answer is :X is nitrogen dioxide, and Y is a metal oxide.
Moles = mass/molar mass, so n(C2H6O)= 16.0 / (12+12+(1x6)+16)
=0.348 (to correct sig figs)
From the calculation, the partial pressure of Cl2 is 1.98 atm. Option B
<h3>What is the equilibrium constant?</h3>
The term equilibrium constant refers to the value that shows us the extent to which reactants are converted into products. We know that the equilibrium constant can only be obtained by the use of the equilibrium partial pressures of each of the species.
Thus we have;
K = p PCl3 . pCl2/pPCl5
p PCl3 = partial pressure of PCl3
pCl2 = partial pressure of Cl2
pPCl5 = partial pressure of PCl5
K = equilibrium constant
Substituting values;
1.05 = 0.463 * pCl2/0.875
pCl2 = 1.05 * 0.875/0.463
pCl2 = 1.98 atm
