The ph of a solution is a measure of the quantity of hydrogen atoms (h) in the solution. it is given by the formula f(x) = −log x.

in the formula, x = [h+], the molar concentration of hydrogen atoms, or the number of moles of hydrogen atoms per liter of solution

oven cleaner: [h+] = 10−13 ph =

water: [h+] = 0.7 ph =

blood: [h+] = 0.4 ph =

vinegar: [h+] = 0.0063 ph =

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

the answer is 9 because the question is telling how much it be together.

i think this is a open ended question but i agree with other guy who said you should ask it at english section
