Answer:
The oxidation number of strontium is +2.
Explanation:
Answer: 0.04M
Explanation:
Tetraoxosulphate(VI) acid has a formula of H2SO4.
The concentration of the whole acid is 0.02M, and there are 2 hydrogens in the formula. That means we multiply 0.02M * 2, giving the answer of 0.04M.
Another visual explanation...
H2SO4 = H2(2+) + SO4(2-)
There are two hydrogens, the double amount of concentration of H2SO4, giving the answer of 0.04M.
