One step in the industrial production of nitric acid is the reaction of ammonia with oxygen gas. 4NH3(g)+5O2(g)-->4NO(g)+6H2O(g) What is the volume of nitrogen monoxide gas that can be produced from 8L of oxygen gas.

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

Explanation:

Equation of reaction:  4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)

From the equation of reaction, 5 moles of oxygen gas produces 4 moles of nitrogen monoxide gas

1 mole of a gas at STP occupies a volume of 22.4 L

5 moles of oxygen gas occupies a volume of 5 * 22.4 L = 112 L

4 moles of nitrogen monoxide as occupies a volume of 4 * 22.4 L = 89.6 L

Therefore, 89.6 L of nitrogen monoxide gas are produced from 112.0 L of oxygen

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 8.0 * (89.6/112

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
