PH+pOH=14
4.5+pOH=14
pOH=14-4.5
pOH = 9.5
We know that
[H⁺][OH⁻]=10⁻¹⁴,so
-log([H⁺][OH⁻])=-log10⁻¹⁴
-log [H⁺]+ (- log[OH⁻])= - log10⁻¹⁴,
- log[H⁺] = pH
- log[OH⁻] = pOH
- log10⁻¹⁴=-(-14)log10=14*1=14
pH + pOH =14
Answer: your answer is A
Explanation: the atoms has the same properties of the same element as the atomic number.
Answer: Carbon emissions
Explanation: Mankind is creating excessive carbon emissions with his factories and machines.
% yield = actual yield divided by theoretical x 100
24.6 divided by 55.9 is 0.44
.44 x 100 =44%
