Question

1) which is the more reactive, magnesium or calcium and why?
2) write the chemical formula for each of the products.
3) write balanced equations for these reactions

Answer 1

Answer:

Calcium is more reactive than magnesium because it is larger than a magnesium atom because it has one more energy level. ... Therefore, calcium is more reactive than magnesium because the valence electrons on the calcium atom is farther from the nucleus. In other words, calcium is more electropositive than magnesium.

Balancing a Chemical Equation. Because the identities of the reactants and products are fixed, the equation cannot be balanced by changing the subscripts of the reactants or the products. ... Balance polyatomic ions (if present on both sides of the chemical equation) as a unit.

Answer 2

1. Calcium is more reactive than magnesium

→because the calcium atom is larger than the magnesium atom. and because the valence electrons on the calcium atom is farther from the nucleus. In other words, calcium is more electropositive than magnesium.

sorry but may be 2nd and 3rd question is half..
