+2 for Mg, -1 for each Cl
The oxidation number of chlorine in MgCl2 is -1. Magnesium is a group 2 element with an oxidation number of +2, and since the compound is neutral, the total oxidation number of the two chlorine atoms must equal -2, making the oxidation number of each chlorine atom -1.
The oxidation numbers of atomic magnesium and atomic chlorine are 0. They react with each other to form magnesium chloride. After the formation of the salt, magnesium ions have +2 oxidation number where that of chloride ions is -1.
a displacement reaction, magnesium displaces hydrogen because it is more reactive
In MgCl2, the oxidation state of Cl is -1 because it is a halogen. Since there are two Cl atoms, the total oxidation state contribution from Cl is -2. This means that the oxidation state of Mg is +2 in order to balance out the charges and form a neutral compound.
First, we calculate the molar mass of MgCl2, which is 95.21 g/mol. Then, we divide the given mass by the molar mass to determine the number of moles of MgCl2. So, 105 g of MgCl2 contains approximately 1.10 moles of MgCl2.

Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
To find the number of formula units of MgCl2 in 11.6g, first calculate the molar mass of MgCl2 (95.21 g/mol). Then, divide the given mass by the molar mass to find the number of moles (0.122 mol). Since 1 mol of MgCl2 contains 1 formula unit, the number of formula units in 11.6g of MgCl2 is also 0.122 mol.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
