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.
Zn + 2H+ ----> Zn2+ + H2
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).
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
Cu(s) + 2H^+(aq) ==> H2(g) + Cu^2+
This reaction is chemically: acid (2H+) is converted tohydrogen (H2) by picking up 2 electrons from a reactive metal. This metal is changed to an ionic salt compound.
