Answer:
When a reversible reaction happens in a closed container, it reaches a dynamic equilibrium . At equilibrium: the forward and backward reactions are still happening. the forward and backward reactions have the same rate of reaction
Explanation:
They are all stable and have eight valence electrons
Answer:
glycerol
Explanation:
it is thick sweet liquid.It is type of alcohol which has 3 OH groups
Answer:
You answer is correct
Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.

The balanced chemical equation for the combustion of butane is:

Δ
= Σ
Δ
-Σ
Δ
=
=[-3148kJ/mol+(-2418.2kJ/mol)]-[(-251.2kJ/mol)+0]
= -5315 kJ/mol
Calculating the enthalpy of combustion per mole of butane:

Therefore the heat of combustion per one mole butane is -2657.5 kJ/mol
Correct answer: -2657.5 kJ/mol
