. Iron is divalent to hydrogen and water.
Answer: The term covalent refers to a type of bonding in which pairs of valence electrons are shared by two atoms. Covalent compounds are those that exhibit covalent bonding. Molecular compounds are a type of covalent compound.
Explanation:
1) Find the number of mols of HCl in 5.2 liters of 4.0M solution:
n = M*V(L) = 4.0 mol/L * 5.2 L = 20.8 mol
2) Find the number of mols of Mg that will react with 20.8 mol of HCl, using the coefficients of the balanced equation
[1mol Mg / 2 mol HCl] * 20.8 mol HCl = 10.4 mol Mg
3) Transform mol to mass using the atomic mass:
10.4 mol Mg * 24.3 g/mol = 252.7 g of Mg.
