Question

Is the decomposition of sodium bicarbonate endothermic or exothermic?

Answer 1

Answer:

decomposition of sodium bicarbonate is an exothermic reaction.

Answer 2

Answer:

Chemical reactions are either endothermic or exothermic. Endothermic means you have to put energy (heat) in to make the reaction go while exothermic means there's energy (heat) left over. Left over heat will raise the temperature. Baking soda and water is exothermic and so the water gets a little warmer.
