What is the correct formula when Mg2 and S2- react?
The correct formula when Mg2+ and S2- react is MgS. Magnesium (Mg) has a 2+ charge, while sulfur (S) has a 2- charge, so they combine in a 1:1 ratio to form magnesium sulfide (MgS).
How many oxygen atoms are in a formula unit of sodium acetate?
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
How many ions does MgBr2 have?
One formula unit of MgBr2 has three ions; one Mg2+ ion and two Br- ions. One mole of MgBr2 formula units has one mole of Mg2+ ions and two moles of Br- ions, for a total of three moles of ions.
What is the formula of a compound formed when mg plus 2 and cl- react?
MgCl2 is formed. Mg2+ + 2Cl- ----> MgCl2

KAl(SO4)2 is the formula unit found in alum. The formula of alum is KAl(SO4)2 .12H2O There are twelve water molecules present per formula unit, it is a sometimes called dodecahydrate.
What is the formula and charge for Nitrate Ion and Mg2?
The formula and charge of the nitrate ion is NO3-, and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium nitrate, Mg(NO3)2.
What is the correct formula when Mg2 and S2- react?
The correct formula when Mg2+ and S2- react is MgS. Magnesium (Mg) has a 2+ charge, while sulfur (S) has a 2- charge, so they combine in a 1:1 ratio to form magnesium sulfide (MgS).
What is the formula for a Magnesium Ion?
The formula for a magnesium ion is Mg2+. This indicates that the magnesium atom has lost two electrons, giving it a positive charge of 2.
What is the chemical formula for magnesium bisulfate?
The chemical formula for magnesium bisulfate is Mg(HSO4)2.
What is the formula and charge for Carbonate and Mg2?
The formula for carbonate is CO3^2-, and it has a charge of -2 due to the -2 charge on each oxygen atom. The formula for magnesium ion is Mg^2+, which has a charge of +2 due to the loss of two electrons.
What is the ionic charge on Mg2?
The ionic charge on "Mg2", presumably meaning the cation whose formula is Mg+2, is +2. In the unlikely event that "Mg2" means a diatomic molecule of elemental magnesium, the ionic charge would be 0,
What is Lewis formula for MgO?
the Lewis formula for MgO is Mg2+[O]2- Which mean Mg loses 2 electrons and O gains 2 electrons to be stable.
How many oxygen atoms are in a formula unit of sodium acetate?
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
What is the formula and charge for carbonate ion and Mg 2?
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
When magnesium Mg2 plus and fluorine F1- combine in an ionic bond the resulting formula will be?
When magnesium Mg2+ and fluorine F1- combine in an ionic bond, the resulting formula will be MgF2. The magnesium ion has a 2+ charge and the fluoride ion has a 1- charge, so two fluoride ions are needed to balance the charge of one magnesium ion.
What is the formula and charge for Hydroxide Ion and Mg-2?
The formula and charge for the hydroxide ion is OH-, and the formula and charge for the magnesium ion is Mg2+. Together they make magnesium hydroxide, Mg(OH)2.
What is the formula for epsom salt?
Mg2+ (aq) + 2OH- (aq) → Mg(OH)2 (s) → Blue complex
