b. Exothermic
the amount of engy put in to brake thebonds is less than the amount geven out by the bonds so thermal engy is given off

b. Exothermic reactions produce heat.
a. Endothermic - takes in heat => test tube feels cold.
b. Exothermic - produces heat => test tube feels hot.
c. Hydrogen - an element that is produced when acids react with metals
d. Buffered - keeping a solution either acidic or alkaline

Doi... is sweet. For any reaction, DeltaH = sum{DeltaHformation(products)} - sum{DeltaHformation(reactants)} to ensure why this must be actual, you should imagine doing the reaction on paper (not truly) with techniques from replacing the reactants to their factors, and then rearranging the elements to grant the products. So this equation is only an social gathering of conservation of power (or, for the more advantageous jargon minded, the actual shown truth that H is a state function autonomous of route)

Exothermic reactions are the ones that ive out heat. HINT: look at the prefix, "exo" is a prefix for outside, e.g. exoskeleton, bugs have exoskeletons!

Exothermic-from the greek exus, meaning produce or give, and thermal, or heat.

B - Exothermic.
Not because I know - but because the other answerers seem to have got it right!!
Thanks for the two points though!
