The best statement
which describes a reaction in a state of equilibrium is letter D. <span>The rate of the forward
reaction equals the rate of the reverse reaction and the </span>concentrations of products and
reactants are constant.
>Chemical equilibrium<span> is defined as<span> the state in which both reactants and products are present
in </span></span>concentrations<span> which have no further tendency to change with time. This state results when the forward
reaction proceeds at the same rate as the </span>reverse
reaction<span>. The </span>reaction rates<span> of the forward and backward reactions are generally not zero,
but equal. Thus, there are no net changes in the concentrations of the reactant(s)
and product(s).</span>

The electricity on which the motor runs represents ATP.
ATP, adenosine triphosphate, is the energy currency of the cell. The energy released during the process of respiration is stored in the ATP molecule, and the ATP is stored within cells. Whenever the cell requires energy for any function, it simply hydrolyzes the ATP molecule, breaking a phosphate group off and releasing energy in the process.
The compound that is formed is: MgI2
Answer:
finding the mass percentage oven element in a compound might sound complicated, but the calculation is simple. For example, to determine the mass percentage of hydrogen in water H2O, divide the major mass of hydrogen by the total molar mass of water and then multiply the result by 100
