First, write out a complete balanced reaction for the combustion of ethane, ethane + O2 -> CO2 + H20. Then, divide the grams of ethane by its Molar Mass and multiply by 32, the molar mass of O2.
I believe that Zinc has two more protons than nickel

Answer:
Heat
Explanation:
Energy exchange occurs when two systems exchange energy between them, or a system exchange energy with its surroundings. This phenomenon can happen in two ways: heat or work.
The heat is the exchange of energy caused by the difference in temperature. So, when the systems lose heat, its temperature decreases, and when it gains heat, its temperature increases.
The work is the energy exchange caused by the difference in volume and pressure. When a gas expands, its volumes increase, and it does work to its surroundings. When it compresses, its volumes decrease and it suffers work from its surroundings.
So, when the wax melt, the temperature of it must have increased, and it has gained heat. The energy exchange as heat.
