Endothermic and exothermic reaction

Answer 1

An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.

Answer 2

Exothermic and Endothermic reactions comes under chemical reactions since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.

Answer 3

Endothermic reaction is which heat is absorbed Exothermic reaction is when heat is released to its surroundings

Answer 4

Endothermic reactions take in heat

Exothermic reactions give out heat

Answer 5

aerobic respiration is exothermic and photosynthesis is endothermic

Answer 6

Endothermic reactions release energy and Exothermic reactions absorb energy during reaction.

Answer 7

An endothermic reaction need heat, an exothermic reaction release heat.

Answer 8

which way the energy goes.
