Chemical equilibrium<span> is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.
</span><span>Or, we can say that in chemical equilibrium the ratio between the concentration of the reactants and the products is constant.</span><span>
Chemical equilibrium is a result state when </span><span>the forward reaction proceeds at the same rate as the reverse reaction.

Isotopes are forms of the same elements which contain equal number of protons but different number of nucleus in their nuclei, thus the differ in relative atomic mass but they have same chemical properties. The mass number is the summation of number of proton and number of neutron of an atom. If the mass number is known, then one need to know the number of proton in the atom in order to calculate for the number of neutron.
Answer:
B.
Explanation:
This is physical change as the popcorn has expanded in size.
Answer:
Dependent on the element that reacted with carbon
Explanation:
Nuclear fusion is the combination of small atomic nuclei into larger ones usually accompanied with the release of a large amount of energy.
From the problem stated, carbon fuses with another atom. The combined atom would have more nuclear particles in terms of protons and neutrons than the combining atoms. This will eventually make it weigh more than carbon and the atom it combines with. The resulting weight will depend on the combining atoms eventually.
Answer:
Water has a chemical formula of H2O . In here, there are two hydrogen atoms and one oxygen atom, and so its mass will be 2+16=18 amu . There are two water molecules formed, and that means the total mass of the products is 18⋅2=36 amu .
