D.) Balanced equation is Zn + 2HBr - - - > ZnBr2 + H2.
What effect does removing predators have on prey?
:It means that as they are removed the predators go hungry and they could become extinct.
Hope I helped!
Answer:
C
Explanation:
As the temperature increases, the kinetic energy of the molecules increases.
Answer:
For H3O concentration you do 10^-pH so if pH is 5 then H3O+ is 10^-5= 1*10^-5 H3O+ ions
For OH is one extra step. First find H3o+ ions using equation above then you have to use that to divide 1*10^-14
So if pH is 5....the H3O+ is 1*10^-5 then OH- = (1*10^-14)/(1*10^-5) = 1*10^-9 OH ions
as far as acid/base pH 0-6 is Acid 8-14 is Base. pH of 7 is neutral. Recheck your work *hint* *hint* water is neutral. Spit is above 7 so is base.
