Answer:
B
Explanation:
Particles in a solid have fixed locations in a volume that does not change. Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
Answer:
The standard reaction enthalpy for the given reaction is 235.15 kJ/mol.
Explanation:
..[1]
..[2]
..[3]
..[4]
Using Hess's law:
Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.
2 × [4] = [2]- (3 ) × [1] - (2) × [3]
The standard reaction enthalpy for the given reaction is 235.15 kJ/mol.
A mole of an element refers to 6.02e23 atoms so they would have the same amount of atoms

Explanation:
The advantages of using natural gas rather than coal are the following,
- Natural gas is present in large amount than coal.
- Natural gas is less costly than other fossil fuel sources of energy.
- It increases security by decreasing dependence.
- Natural gas is more environmentally friendly.
- Natural gas is much safer to store.
- It is reliable.
- Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
- Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.
