This means that there is 1 magnesium atom and 2 chlorine atoms.

The "2" means that there's 2 of that atom. You could ditch the "2" but its not 'right' and if your a student having the 2 will give you a higher mark.

Whoever made the first answer made it way to complected.

What is the difference between MgCl and MgCl2?

MgCl is magnesium chloride with a 1:1 ratio of magnesium to chlorine atoms, while MgCl2 is magnesium chloride with a 1:2 ratio of magnesium to chlorine atoms. This means that MgCl has one chlorine atom for every magnesium atom, while MgCl2 has two chlorine atoms for every magnesium atom.


Use enthalpies of formation to determine the H reaction for the reaction MgCl2 s equals MgCl2 aq?

To determine the enthalpy change (ΔH) for the reaction of solid magnesium chloride (MgCl2(s)) dissolving in water to form aqueous magnesium chloride (MgCl2(aq)), you can use the standard enthalpies of formation ((ΔH_f^\circ)) of the substances involved. The reaction can be represented as: [ \text{MgCl}_2(s) \rightarrow \text{MgCl}_2(aq) ] The enthalpy change for the reaction can be calculated using the formula: [ ΔH_{reaction} = ΔH_f^\circ(\text{MgCl}_2(aq)) - ΔH_f^\circ(\text{MgCl}_2(s)) ] By substituting the standard enthalpies of formation for MgCl2(aq) and MgCl2(s) from tables, you can find the ΔH for the dissolution process.

Is MgCl² ionic or molecular?

MgCl2 is an ionic compound. It is composed of magnesium cations (Mg2+) and chloride anions (Cl-), which are held together by ionic bonds.


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.


What is the chemical formula of magnesium and chloride?

Magnesium chloride has MgCl2 as its chemical formula. This ionic salt loves water, and will "suck it out of the air" to form MgCl2(H2O)x as it absorbs moisture. More can be found on this substance in the Wikipedia post, and a link is provided.


What does MgCl2 stand for in the table of elements?

MgCl2 stands for magnesium chloride. Magnesium (Mg) is an element and chlorine (Cl) is an element, both found in the periodic table of elements. MgCl2, however, is a compound made of these two elements, and it would not be found in the table of elements.
