The most common solvent is- Water. Water can dissolve in various different substances, and it dissolves more substances than any other liquid. In fact, some people call it the<em>"universal solvent".</em>
The equilibrium constant of a reaction is defined as the ratio of the concentrations of the products over the reactants.
I'm sorry if this does not answer your question, although I tried my best.
The answer is option D
That is when an electric current is passed through liquid water, hydrogen gas accumulates at one electrode and oxygen gas accumulates at the other, a chemical change has occurred with energy being absorbed.
This process is called electrolysis of water in which hydrogen gas accumulates at one electrode and oxygen gas accumulates at the other. In it decomposition of water occurs chemically using electricity as the energy source.
The Correct option is E. Chemical energy to Mechanical energy.
In chemical reactions, elements or compounds called reactants, are changed into other substances or compounds and elements called products. You cannot change one element into another in a chemical reaction. They are both important in order to classify the reaction.
