Acompound contains nitrogen and a metal. this compound goes through a combustion reaction such that compound x is produced from the nitrogen atoms and compound y is produced from the metal atoms in the reactant. what are the compounds x and y? x is nitrogen dioxide, and y is a metal halide. x is nitrogen dioxide, and y is a metal oxide. x is nitrogen gas, and y is a metal sulfate. x is nitrogen gas, and y is a metal oxide.

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.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
