<h3><u>Answer;</u></h3>
Hydroelectric power
<h3><u>Explanation</u>;</h3>
- Hydroelectric power is produced when a turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
- Hydroelectric power plants uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
A chemical formula of a molecule is an expression which states the number and type of atoms<span> present in a </span>molecule of a substance. While the structural formula, is a formula of <span>a chemical compound that is a graphic representation of the molecular </span>structure<span>, showing how the atoms are arranged.</span>
A. mechanical energy because it can be either potential or kinetic energy and it wouldn't be d because moving energy is the same as kinetic energy.

The reactants of photosynthesis are represented by 
and 
.
<h3>Photosynthesis</h3>
It is a reaction through which green plants make use of inorganic products such as water and carbon dioxide in the presence of solar radiation to make sugar. Oxygen is liberated as a by-product.
The equation of the reaction is represented by:
Thus, the reactants are represented by and respectively.
