Answer:
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. ... Methane combining with 2 oxygen to form carbon dioxide, water and heat.
9.98 g of NH₃ reacts with 23.4 g of O₂ (up to 3 significant figure).
<h3>What is Significant figures ?</h3>
The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.
The given chemical equation ;
4NH₃ + 5O₂ ---> 4NO + 6H₂O
Therefore,
4 moles of NH₃ reacts with 5 moles of O₂.
i.e,
68 g of NH₃ reacts with 160g of O₂.
Therefore,
9.98 g of NH₃ reacts with :
= 160/68 x 9.98
= 23.4 g of O₂ (up to 3 significant figure)

Both has the same molecule, CO2 molecule is 1 mole and NH3 molecule is 1 mole too.
Their atoms are different.
1 mole of (means 1 molecule) carbondioxide : 1 mole of O and 2 moles of C = 3 moles of atom (one mole of CO2 made by 3 moles of atom)
1 mole of (means one molecule) ammonia : 1 mole of N and 3 moles of H =4 moles of atom ( One mole of NH3 made by 4 moles of atom )
The answer is B.
sorry for my bad English btw, I tried to explain as far as I can.
Hope it helps!
