Answer:
This is because it is a physical change not a chemical change.
2H⁺(aq) + Zn(s) ----> H2(g) + Zn²⁺(aq)
2H⁺(aq) +2e⁻ ----->H2(g) reduction
<span><u>Zn(s) ------>Zn²⁺ +2e⁻ oxidation</u>
</span>2H⁺(aq) + Zn(s) -----> H2(g) + Zn²⁺
Answer:
Two
Explanation:
Nitrate has a charge of negative 1 and the Iron (II) tells us the iron in that formula has a charge of +2, so in order for the iron to have to equal positive two, there has to be two negative. Since on nitrate ion is -1, you need two to make -2.
