1.How many grams of zinc Zn and oxygen O2 will be needed to form 324 grams of ZnO after the reaction?

The answer is bhope this

Answer; carbon monoxide (co);

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

Ibelieve it’s 1.95m
