Answer everything on here please including the examples

12. complete each of the following word equations for synthesis reactions. a. sodium + oxygen -> b. magnesium + fluorine -> 13. complete and balance the equations for the decomposition reactions. a. hgo -> [with the triangle heat symbol above the arrow] b. h2o(l) -> [with "electricity" written above the arrow]

Which produce would best increase the amount of heat energy that is actually gained by calorimeter b

Chemical kinetics what was the rate of reaction in trial 3? choose the closest answer.
