Why the formula of magnesium chloride is MgCl2?
Magnesium chloride is an neutral ionic compound. In neutral ionic compounds, the positive charge of the cations must balance out the negative charge of the anions. In the case of magnesium chloride, magnesium is the cation with an ionic charge of +2 and chlorine is the anion with an ionic charge (each) of -1. Since two chlorine anions together have a charge of -2 total, they balance out the one magnesium cation with a charge of +2.
What is the formula for an ionic compound that contains the elements magnesium and chlorine?
Magnesium ions have a 2+ charge, while chloride ions each have 1- charge. In order to cancel out the charges to create a stable, neutral compound, the formula must be MgCl2.
Is Magnesium Chloride soluble in Hexane?
Magnesium chloride is an ionic salt. Hexane is a non polar solvent. So, magnesium chloride is unsoluble in hexane.
What two words describe magnesium chloride?
Magnesium Chloride is a compound. It contains Magnesium(Mg) and Chlorine(Cl). It is also a pure salt. Magnesium chloride is chemically bonded together.
What does magnesium oxide plus hyrdrochloric acid make?
hydrochloric acid + magnesium => magnesium chloride + hydrogen 2HCl + Mg => MgCl2 + H2
How many chloride ions are needed to cancel the 2 charge of magnesium in magnesium chloride (MgC12)?
Two.
What is the chemical equation for magnesium plus chlorine?
Magnesium has a charge of +2 and Chloride has a charge of -1. In order to make magnesium chloride have a net charge of zero, there must be twice as much of the chloride ion than the magnesium ion. The ratio of magnesium to chloride is therefore 1:2. With this knowledge, we can write the chemical equation MgCl2.

What does the formula for the compound magnesium chloride MgCl2 tell you about how many chloride ions are needed to cancel out the charge of magnesium?
Two
The correct name for the compound MgCl3 is?
Mg has a +2 charge and Cl has a -1 charge.The correct formula is MgCl2
How many chloride ions are present in a formula unit of magnesium chloride given the charge on a mg ion is 2 plus?
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.

What is the charge for silver chloride?
The overall charge for any compound is balanced. The charge for Ag is +1, and the charge for chloride is -1. They cancel each other out.
What do magnesium ions do?
Magnesium ions have a charge of 2+ and will react with negative ions to form ionic compounds with an overall charge of 0.
WHAT IS MgCl2?
MgCl2 is the chemical formula of magnesium chloride.
