It's MgCl2, and yes, it is soluble. It's an ionic compound, and ionic compounds are very polar. Water is polar as well, so magnesium chloride easily dissolves in water.

How many atoms does MgCL have?

If unbalanced the molecule MgCl will have one atom of Mg and one of Cl and therefore two atoms. in real life you would not have MgCl, you would have MgCl2 (where 2 is a subscript). This means there is one atom of Mg and two of Cl and therefore 3 atoms in total.


Why magnesium chloride is MgCl²?

Magnesium chloride is represented as MgCl₂ because it consists of one magnesium ion (Mg²⁺) and two chloride ions (Cl⁻). Magnesium has a +2 charge, while each chloride ion has a -1 charge. To balance the charges, two chloride ions are needed for every magnesium ion, resulting in the formula MgCl₂. This reflects the stoichiometry of the compound, ensuring overall electrical neutrality.


Is chalk soulble?

Chalk is essentially calcium carbonate, CaCO3, and in not soluble in water to any significant extent.


What is the percent composition of CI in MgCI2?

To find the percent composition of chlorine (Cl) in magnesium chloride (MgCl₂), first calculate the molar mass of MgCl₂. The molar mass of magnesium (Mg) is approximately 24.31 g/mol, and that of chlorine (Cl) is about 35.45 g/mol. Thus, the molar mass of MgCl₂ is 24.31 + (2 × 35.45) = 95.21 g/mol. The percent composition of Cl is then calculated as (2 × 35.45 / 95.21) × 100%, which is approximately 74.4%.


Is MgCl An Acid?

Magnesium chloride (MgCl2) is not an acid. It is a salt that is composed of magnesium ions (Mg2+) and chloride ions (Cl-). When dissolved in water, it dissociates into its respective ions but does not release H+ ions like an acid.
