It cannot because Mg appears only once.
The balanced chemical equation for the reaction of mercury (Hg) with hydrochloric acid (HCl) is: Hg + 2HCl -> HgCl2 + H2
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
The balanced chemical equation for the reaction C2H2 + H2 → C2H6 is: C2H2 + 2H2 → C2H6
Sodium hydroxide does not react with hydrogen gas.
The balanced chemical equation for the reaction of mercury (Hg) with hydrochloric acid (HCl) is: Hg + 2HCl -> HgCl2 + H2
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
The balanced chemical equation for the reaction C2H2 + H2 → C2H6 is: C2H2 + 2H2 → C2H6
Sodium hydroxide does not react with hydrogen gas.
The balanced equation is: 2Ag + 2HgNO3 -> Hg + Hg(NO3)2 + 2AgNO3. This is obtained by balancing the number of atoms on both sides of the equation.
It is not balanced. There should be a 2 in front of H2 and H2O
Co + 2h2 -> ch3oh All letters capitals!
The balanced equation for the reaction between sodium and hydrogen gas to form sodium hydride is: 2 Na + H2 -> 2 NaH
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
2h2 + o2 -> 2h2o All letters capitalized!!
