Answer:
9.90
Explanation:
ph= -log (H+) = -log( 1.25×10^-10)
which equals to 9.903
so the answer is 9.90
Explanation:
An chemical reaction is said to be at equilibrium when the concentration of reactant and products become constant.In an equilibrium reaction the forward rate and backward rate of the reaction is equal.
When the forward rate of the reaction is greater than the backward rate the of the reaction the concentration of product will get increase and concentration of reactants will get decrease and vice versa
In a chemical reaction at equilibrium, the rate of the forward reaction is <em>equal </em>the rate of the reverse reaction. If the rate of the forward reaction <em>greater </em>more products are formed.
last one :H202 is hydrogen peroxide so its not water it is simmilar but its NOT water.
i dont know the other ones.
