The hydrogen is recovered as its most stable oxide. when, Ask an Expert

Academics

Analysis of a compound shows that it only contains the elements carbon, hydrogen, nitrogen, and oxygen. The following results were obtained from a 2.37 kg sample of the substance:

i. All of the nitrogen is recovered as nitric acid. It takes 7.500x10^3 mL of 2.825 Molar barium hydroxide solution to neutralize the acid.

ii. The hydrogen is recovered as its most stable oxide. When the oxide was made to decompose completely it released 1.274x10^25 molecules of oxygen gas.

iii. The compound is 42.87% carbon by mass

A. Write the balanced chemical equation

B. How many moles of the atomic nitrogen are present?

C. How many moles of atomic hydrogen are present?

D. How many moles of carbon are present?

E. How many moles of atomic oxygen are present?

F. What is the empirical formula of the compound?

G. In a separate experiment it was found that when 336.0 g sample was vaporized, it occupied a volume of 67.2 L at STP. What is the molecular formula of the compound?
