Because this reaction results in a solution containing free ions; a strong strong acid (due to the Cl) and a strong base (due to the Mg). Strong acids and strong bases are good conductors.
(Do note that the general solution is pretty much neutral, just slightly acidic as Cl forms a stronger acid than the base formed by Mg)

hydrochloric acid + magnesium => magnesium chloride + hydrogen 2HCl + Mg => MgCl2 + H2
insulator.
The reaction between MgO and H2O is a chemical reaction called a hydration reaction. In this reaction, MgO reacts with water to form magnesium hydroxide (Mg(OH)2).
The balanced equation for the reaction between HNO3 and NaHCO3 is: 2 HNO3 + NaHCO3 → NaNO3 + H2O + CO2
Mg2 HCl= Mg+HCl2 ______________________________ Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g) That should be correct. The topmost answer is the decomposition of MgHCl, it looks like.
MgO+2HCl = MgCl2+H2O
You begin with 1.63 g of MgCl2•xH2O. You end up with 0.762 g MgCl2. That means you lost 1.63 - 0.762 = 0.87 g of H2O. 0.762 g MgCl2 / 95.21 g (molar mass) = .00800 mol MgCl2 0.87 g H2O / 18.02 g (molar mass) = .048 mol H2O x = mol solute / mol solvent x = .048 mol H2O / .00800 mol MgCl2 x = 6 MgCl2•6H2O
: since Magnesium oxide is a insoluble oxide but Magnesium chloride is a soluble salt, : chemical equation : : HCL(aq) + MgO(s) -----> MgCl(aq) + H2O(l) : HENCE, : ionic equation of Hydrochloric acid and Magnesium oxide: : H+(aq) + MgO(s) ----> Mg2+(aq) + H20(l)
Magnesium chloride plus hydrochloric acid does not have a reaction to each other. Therefore, each chemical keeps its original name.
2HCl + MgO --> MgCl2 + H2O
The chemical equation for magnesium (Mg) reacting with hydrochloric acid (HCl) is: Mg + 2HCl -> MgCl2 + H2 In this reaction, magnesium displaces hydrogen in hydrochloric acid to form magnesium chloride and hydrogen gas.
MgO + 2HCl =MgCl2 +H2O
2HCl + Mg(OH)2 ------> H2O + MgCl2
When hydrochloric acid is added to solid magnesium oxide, a chemical reaction takes place in which hydrogen gas is produced and magnesium chloride is formed. The reaction can be represented by the equation: MgO + 2HCl -> MgCl2 + H2.
The word equation for magnesium oxide plus hydrochloric acid is: magnesium oxide + hydrochloric acid → magnesium chloride + water.
mg(oh)2+2h2o ------ mgcl2 + h2o
The chemical formula for carnallite is KMgCl3.6(H2O)An alternative formula is MgCl2.KCl.6H2O
