Answer:
Energy by definition is the property of matter that involves interactions with molecules, in order to perform an action.
Explanation:
They're many different types of energy, a few of them are...
. Thermal energy
. Solar energy
. Chemical energy
. Kinetic energy
. Potential energy
. Mechanical energy to name a few...
All of these specific energies involve the interaction of molecules which are used for different things and can be converted from one type of energy to another.
Hope this helps.

Answer:
Ex1.
a) Carbon : atomic number Z = 6 and mass number A = 12
b) Protons = 6; electrons = 6 ; neutrons = 6.
Ex2.
Molar mass of H₂O₂ = 34 g; BaF = 156 g; CO = 28 g.
Explanation:
Ex1.
a) the element with atomic number 6 and mass number 12 is carbon
b) number of protons and electrons in a element is given by its atomic number; and for neutrons its mass number - atomic number (A-Z).
⇒ protons = Z = 6; electrons = Z = 6.; neutrons = A-Z = 12-6 = 6.
Ex2.
Molecular formula of hydrogen peroxide is given by H₂O₂.
⇒ molar mass = 2×mass of hydrogen + 2×mass of oxygen
⇒ molar mass = 2×1 + 2×16 = 34.g
molar mass of BaF = mass of barium + mass of fluoride.
= 137 + 19 = 156 g
molar mass of CO = mass of carbon + mass of oxygen
= 12 + 16 = 28 g
