Question

a sample of nitric acid yeilds 1.6gm of oxygen . Give a balanced chemical reaction​

Answer 1

Hiii MATe ☺☺

From the balanced reaction: One mole(or 1 molecule or 16 g) of

reacts with 2 moles (or 2 molecules or 64 g) of oxygen to give one mole (or 1 molecule or 44 g) of

and 2 mole (or 2 molecules or 36 g) of water.

For the gaseous system at STP:

22.4 L methane reacts with 44.8 L of oxygen to give 22.4 L of CO and 44.8 L of water.
