Answer:
pH= 1.70
Explanation:
I 4.988 0 0
C -x +x +x
E 4.988 -x x x
8.0 x 10^-5 = X^2/ 4.988 - x
(since the X value is so small, round 4.988-x to 4.988 because X is close to zero)
8.0 x 10^-5 = x^2/4.988
x4.988 x4.988
4.0 x 10^-4 = x^2
x = .0199
pH=-log[.0199] = 1.70
You are exposed to nuclear radiation every day is true!
Answer:
Protons Neutron Electrons
hydrogen-1 1 0 1
hydrogen-2 1 1 1
hydrogen-3 1 2 1
Explanation:
hydrogen-1, hydrogen-2, and hydrogen-3 are all isotopes.
Isotopes have the same number of protons but a varying number of neutrons. Protons = Electrons.
