Net ionic equation of reacting magnesium with hydrochloric acid?

Answer 1

Mg (s) + 2H+ (aq) + 2Cl- (aq) ---> Mg+2 (aq) + 2Cl- (aq) + H2 (g) The spectator ions 2Cl- (aq) can be cancelled out as they appear on each side of the equation, so the net ionic equation is:- Mg (s) + 2H+ (aq) ------> Mg+2 (aq) + H2 (g)

Answer 2

Magnesium Chloride

Magnesium Chloride compromises of the two elements Magnesium (Mg) and Chlorine (Cl). Since this is an ionic bond, the atoms gain and loose electrons to form ions (atoms with a charge, or an unequal number of protons and electrons).

Looking at Magnesium's position in the Periodic Table, we can see it is positioned in group IIA, or group 2. This means it combines to make a stable outer shell by loosing two electons (rather than gaining six), giving it a valence charge of 2+.

Chlorine's position in the periodic table is in group VIIA, or group 17. This means it combines to make a stable outer shell by gaining one electron (rather than loosing seven), giving it a valence charge of 1-.

So, Chlorine needs to find one electron, and it sees the Magnesium atom. "Success!" it thinks, and so it binds to the Magnesium. Despite this, the magnesium is still wanting to give away another electron. How about another Chlorine atom joining? Sounds great. In the end we have a Molecule, MgCl2.

Sodium HydroxideSodium Hydroxide compromises of the three elements Sodium (Na), Oxygen (O) and Hydrogen (H). In this circumstance, the Oxygen and Hydrogen atoms have already combined to form a hydroxide ion (OH)-, which has a valency of negative one.

Sodium's position in the periodic table is in group IA, or group 1. This means it combines to make a stable outer shell by loosing one electron (rather than gaining seven), giving it a valence charge of 1+.

If the Sodium atom needs to give one electron, and the Hydroxide ion wants to receive one, then its all happy days. They will combine ionically to from Sodium Hydroxide, molecule NaOH.

Answer 3

The net ionic equation for the reaction between magnesium and hydrochloric acid is: Mg(s) + 2H+(aq) -> Mg2+(aq) + H2(g). Magnesium reacts with hydrogen ions from hydrochloric acid to form magnesium ions and hydrogen gas.

Answer 4

Mg+2H(^+)+2Cl(^-)-->Mg(^2)+2Cl(^-)+H2 Cancel out the Cl's, because they dont change, and your ionic equation is: Mg+2H(^+)-->Mg(^2)+H2

Answer 5

magnesium + hydrochloric acid -> magnesium chloride + hydrogen
