Explanation:
The balanced chemical equation is given as:
2H₂O₂ → O₂ + 2H₂O
А There are two peroxide molecules on the reactant side.
The statement is correct because the left hand side is the reactant side. We can read the reaction as;
2 molecules of hydrogen peroxide decomposed to given 1 molecule of oxygen gas and 2 molecules of water .
D Mass must be conserved so there are an equal number of molecules in the reactants and products.
E Mass must be conserved so there are an equal number of atoms in the reactants and products.
Since the chemical equation is balanced, choices D and E are correct. The reaction will have equal number of molecules and atoms on both sides of the expression.

I hope this helps u and u get it right :D
Hot water, as in very hot water, goes to steam with an enormous change in volume and pressure. This is capable of driving turbine blades, which in turn rotate enormous copper (eg) wired coils in enormous magnetic fields. This in turn produces electricity via electromagnetic induction and Fleming's right hand (I think it is) DYNAMO rule. That goes down miles and mile of v heavy conducting wire/cable as electricity.
Explanation:
The law of conservation of energy is one of the fundamental laws of science that helps to understand energy in nature.
Energy is the ability to do work. There are different forms of energy.
Generally, energy is classified into potential and kinetic forms of energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Kinetic energy is the energy due to the motion of a body.
There are different forms of kinetic and potential energy and they are related by the law of conservation of energy.
The law states that "in an isolated system, energy is neither created nor destroyed by transformed from one form to another".
An isolated system is a system in which there is no exchange of matter and energy.
Due to this we know that no new energy is created or destroyed, they are only transformed from one form to the other.
