☆☆☆☆☆Some teachers will say that electricity is kinetic energy because it involves moving electrons. The problem with this is that the electrons' kinetic energy is not what provides energy to the light bulb or device. This is apparent when you consider that the electric current going into, say, the light bulb filament, is the same as the current going out of it. So that's not what's supplying the energy. The energy actually gets transferred by the electromagnetic field SURROUNDING the wires, not by the electrons IN the wires. So it's really misleading to say that electricity is a form of kinetic energy.

Nearly always, but there are compounds which formed endothermically, so their decomposition gives out energy.
Both conduction and convection. Conduction involves the small movements of individual particles, convection can be on a much larger scale with a hot liquid or gas rising and a cool liquid or gas dropping.

balanced equation
The number in front of a chemical formula is called a coefficient.
False,Only coefficients can be changed in order to balance a chemical equation. Subscripts are part of the chemical formula for reactants or products and cannot be changed to balance an equation.
