Answer: Equilibrium
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction which means the products are being made as quickly as reactants
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
Answer:
To find the mass percent of hydrogen in hydrogen chloride, we must divide the weight of the hydrogen atom alone by the weight of the entire molecule. Then we multiply by 100% to find the percentage. Thus, 2.77% of the mass of hydrogen chloride is hydrogen.

Answer:
c.) pure substances reacting
For ever molecule of MgCl2, there are 2 Cl atoms.
1.81 x 10^24 molecules MgCl2 x 2 = 3.62 x 10^24 atoms Cl
3.62 x 10^24 atoms Cl x 1 mol / 6.022 x 10^23 = 6.01 moles Cl
