Is large amounts of energy are released during chemical reactions?

Answer 1

Depending on the particular chemical reaction, energy may be either released or absorbed.

Answer 2

Yes, it can. Chemistry is the science between the making and breaking of bonds, correct? So, there are two general kinds of reactions: Endothermic (ones that absorb energy) and exothermic (ones that release energy). Endothermic reactions involve forming bonds that store more chemical energy than the original substances (reactants). This energy is supplied in various forms from the surroundings.

Answer 3

Yes light can be absorbed. That's exactly what black fabric and black paint do ...

they both absorb all the visible light that shines on them, and wind up looking black,

just like a place where there's no light at all.

Answer 4

Yes, when you step down - energy is absorbed by the power of your foot to the floor. When a box hits the punching bag - his energy is absorbed into the bag. When a force is propelled into an object - it is absorbed.

Answer 5

YES!!!

On an energy diagram the two reactants often require heat energy to start, this is the Activation Energy.

The diagram will reach a peak, and the fall. If it does not fall as far as the starting energy for the reactants, then it is an endothermic reaction.

Answer 6

Yes, large amounts of energy can be released during chemical reactions. This energy is usually in the form of heat and can be seen in exothermic reactions where the total energy of the products is lower than the total energy of the reactants, resulting in the release of excess energy.

Answer 7

Yes. A reaction that 'absorbs' energy is called an endothermic reaction.

Answer 8

This depends on the the specific chemical reaction.

Answer 9

Yes, for ex. thermal energy.
