The balanced equation is: 2Al(s) + 3Zn(NO3)2(aq) -> 2Al(NO3)3(aq) + 3Zn(s)
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
Balanced :2 K + 2 H2O ----> 2 KOH + H2
The next logical step in balancing the equation would be to change the subscript of the nitrogen molecule to a one.
In the given equation, sulfur is in the gaseous state (S(g)).
The balanced equation is 2Na + CaCl2 → 2NaCl + Ca. This is achieved by ensuring the same number of atoms of each element appear on both sides of the equation. In this case, balancing the equation required doubling the coefficient of NaCl and Ca.
the answer is 2 apex
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
Its balancing is very simple, 2SO2 + O2 = 2SO3
115
The equation given is correctly balanced, because it contains the same numbers of each kind of atoms in the reactants as in the products.
Solve the following equation for A : 2A/3 = 8 + 4A
Balanced :2 K + 2 H2O ----> 2 KOH + H2
The balanced equation for the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2.
undefined.
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.
