One of the main reasons that nuclear fusion is not yet being used in power plants is because of the

a)extreme conditions needed to overcome the repulsion between the atoms.
b) dangerous pollutants produced by this type of nuclear reaction.
c)difficulty in attaining the hydrogen atoms needed for the reaction.
d)harmful radioactive elements produced by the reaction.

The correct answer is option A

Explanation:

Fusion is quite difficult than the fission reaction. In fission an atom is bombarded with a neutron or any charged particle but in a fusion two positively charged particles are brought closer to each other and are made to fuse. The two positively charged particle repels with strong force and thus extreme energy is required to bring them close. Thus fusion is yet a problem in energy production

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
