Answer:
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
The explanation of the how the various concentrations of acid will affect the amount of limestone has been given below.
Effects of acid rain on limestone:-
- When an acid combines with a carbonate, it produces carbon dioxide as a gas and forms a salt that is soluble in the carbonate and acid's water.
- There are several gases in the atmosphere that can dissolve in precipitation such as rain and snow.
- Some may produce acids in rain water, such as carbonic acid, sulfuric acid, and nitric acid.
- Because the concentration is modest, the rain is not highly acidic, but it is acidic enough to react with the carbonates that make up limestone.
Thus we discussed the affects of acid rain on limestones above.

electron dot structure
Explanation:
Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.
- The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
- The chemical symbol represents the nucleus and all electrons except the valence ones.
- The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
- Chlorine has 7 valence electrons in its outermost shell.
- It is made up of 3 lone pairs and 1 odd pair of electron.
- The odd pair accounts for the reason why chlorine is very reactive.
- It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.
