Electrons cause it is the right answer
The relationship between H+ ion concentration and pH is pH=-lg[H+]. So the pH of the solution is -lg(1.25*10^-10) = 9.9.
The term that is used to describe the average kinetic energy of the molecules in a shape is The kinetic theory.
Answer:
Option A = 1:1
Explanation:
The atoms of calcium and sulphur when react their ration is 1:1. The charge on calcium is +2 and on sulphur is -2.
Ca⁺²S⁻²
The +2 and -2 charges are cancel out and overall charge will be zero.
CaS
so their atomic ratio will be 1:1
