No, it is covalent.
(Hint: as it consists of only one element, it cannot be ionic)
the formula for an ionic compound that contains the elements magnesium and sulfur.Mg + H2 SO4 -> Mg SO4 + H2. .
Hydrogen gas (H2) is a covalent molecule because it is formed by the sharing of electrons between the two hydrogen atoms. Ionic compounds are formed by the transfer of electrons between atoms, not sharing.
The molecular equation for the reaction between calcium and water is: Ca(s) + 2H2O(l) -> Ca(OH)2(aq) + H2(g). The net ionic equation for the reaction is: Ca(s) + 2H2O(l) -> Ca^2+(aq) + 2OH^-(aq) + H2(g).
Zn + 2H+ ----> Zn2+ + H2
Hydrogen gas is formed by air-born H2 molecules. Each H2 molecule consists of 2 hydrogen atoms, covalently bonded by overlapping 1s electron orbitals. So no, hydrogen gas is not an ionic bond, it is a covalent bond.
If you mean is the bond in hydrogen gas, H2 ionic then the answer is no.
The chemical equation is:Mg + H2SO4 = MgSO4 + H2
Mg(s) + H2SO4(aq) ==> MgSO4(aq) + H2(g) ... molecular equationMg(s) + 2H+(aq) + SO4^2-(aq) ==> Mg^2+(aq) + SO4^2-(aq) + H2(g) ... ionic equationMg(s) + 2H^+(aq) ==> Mg^2+(aq) + H2(g) ... net ionic equationSpectator is SO4^2- (sulfate ion).
Ca(solid) + 2H2O(liquid) ---> Ca(OH)2(aqueous solution) + H2(gas)Here is the word equation if needed!Calcium + Water ---> calcium Hydroxide + HydrogenHope it helped! =)
Zn + HCl ---> ZnCl2 + H2 ZINC CHLORIDE IS THE ANSWER
The net ionic equation for magnesium reacting with hydrochloric acid is: Mg(s) + 2H+(aq) -> Mg2+(aq) + H2(g) This equation shows the essential chemical species involved in the reaction and highlights the change in oxidation states.
Cu(s) + 2H^+(aq) ==> H2(g) + Cu^2+
