∙ 13y agoFirst of all write down the BALANCED reaction equation.
Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)
We note that the molar ratios are 1:2::1:1
Next calculate the moles of Mg
mol(Mg) = 4.3 / 24.3 (Atomic Mass)
mol(Mg) = 0.17695...
Hence by equivalence with the mole ratios
0.17695... moles of MgCl2 are produced.
NB
1:2::1:1 becomes 0.17695 , 0.353909...:: 0.17695...:0.17695...
695... : 0.

∙ 13y agoMg + 2HCl --> MgCl2 + H2
4.3g Mg x 1 mol Mg/24.30g x 1 mol MgCl2/1 mol Mg = 0.18 mol MgCl2
These two substances readily react to produce magnesium chloride and hydrogen gas, The reaction equation is Mg(s)+ 2HCl(aq) = MgCl2(aq) + H2(g)
Mg has a +2 charge and Cl has a -1 charge.The correct formula is MgCl2
Shandong Bailukai Fine Chemical Co.,Ltd is one of the pioneer manufacturer of magnesium chloride. Their magnesium chloride is without sulphate. About 5000 tons is produced per month.
(NH4)2CO3+2HCl=H2O+CO2+2NH4Cl ammonium carbonate+hydrochloric acid=water+carbondioxide+Ammonium chloride It can also form ammonium chloride and hydocarbonic acid
We hear a popping sound because of the presence of hydrogen gas and hydrogen gas burns completely when exposed to fire.
Well if you put magnesium with hydrochloric acid, the magnesium reacts with it and creates hydrogen and magnesium chloride. Here is the word equation... Magnesium + Hydrochloric acid --> Magnesium chloride + Hydrogen
These two substances readily react to produce magnesium chloride and hydrogen gas, The reaction equation is Mg(s)+ 2HCl(aq) = MgCl2(aq) + H2(g)
1 Mole of Magnesium (Mg) would react with 2 Moles of Hydrochloric acid (HCl), to produce 1 Mole of Magnesium Chloride (MgCl2) (Salt), and 1 Mole of Hydrogen gas (H2).
Remember the general acid reaction eq'ns. Acid + Alkali = Salt + Water Acid + Base = Salt + Water Acid + Metal = Salt +Hydrogen Acid + Carbonate = Salt +Water + Carbon Dioxide. So if you react hydrochloric ACID with a METAL it will produce the gas HYDROGEN.
Magnesium Chloride - MgCI2
Mg + 2HCl → MgCl₂+ H₂ When a metal reacts with an acid a salt and hydrogen are produced.
