Abattery has chemical energy, which can be used to generate thermal and radiant energy in a lightbulb. which best explains what happens to the amount of energy in this scenario? the total energy in the system increases because chemical energy creates thermal and radiant energy. the total energy in the system decreases because chemical energy disappears as thermal and radiant energy are generated. the total energy in the system remains the same as the decrease in chemical energy equals the increase in thermal and radiant energy. the total energy in the system remains the same as the increase in chemical energy equals the decrease in thermal and radiant energy.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
