Balance in equation Mg plus Cl?
The balanced chemical equation for the reaction between magnesium (Mg) and chlorine (Cl) to form magnesium chloride (MgCl2) is: 2Mg + Cl2 → 2MgCl
Is Mg and Cl- in MgCl2 an example of a hydrogen bond?
No, Mg and Cl- in MgCl2 do not form a hydrogen bond. A hydrogen bond is a specific type of bond that forms between a hydrogen atom and an electronegative atom like oxygen, nitrogen, or fluorine. In MgCl2, the bonding involves ionic bonding between the positively charged magnesium ion (Mg2+) and the negatively charged chloride ions (Cl-).
What is the empirical formula for magnesium oxide?
MgCl2 is the correct formula, or two atoms of Cl for each 1 atom of Mg. You could also say 2 moles of Cl atoms for every 1 mole of Mg atoms. The empirical formula should be written with the subscripts in lowest whole number terms. Note that this formula is consistent with the fact that an Mg cation is Mg+2 and a Cl anion is Cl-1. Given these charges, a formula of MgCl2 is the one with the smallest whole number subscripts that will allow the charge of the compound to be zero. See related question below for more details on how to find empirical formulas.
What is positive ion Mg and negative ion Cl chemical formula and name?
Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2(H2O)x. These salts are typical ionic halides, being highly soluble in water.
In the reaction MgCl2 plus 2KOH---Mg(OH)2 plus 2KCl if 3 moles MgCl2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
Potassium hydroxide is the limiting reagent.
