What is the difference between stored energy and usable energy

In biology, the energy that is stored in the bonds between compounds is termed as the chemical energy. This chemical energy is released and converted into different forms according to the functions of the body.

Potential energy can be described as the energy that is stored in an object. In physics, the energy that an object possesses while at rest is termed as the potential energy.

The energy that can be used during work is termed as the kinetic energy. In physics, kinetic energy can be described as the energy that an object possesses while in motion.

1. (a) delivered volume, (b) to reach, (a) moles

2. (c) molar ratio

3. (b) acid solution before.

Explanation:

1. You must titrate the acid with a base solution of known concentration, and use the (a) delivered volume. At the endpoint, the moles of acid and base in the titration follows the chemical equation, thus, you need (b) to reach the endpoint. With volume and concentration of the base we can find its (a) moles

2. With the (c) molar ratio, we can relate the moles of base with the moles of acid

3. When we have the moles of acid, we just need the volume of (b) acid solution before the titration to find molarity of the acid.
