Mg + Cu(NO3)2 = Cu + Mg(NO3)2, Balance the Chemical Equation - Topblogtenz Substitute the final integer coefficients back into the chemical equation 1 Mg + 1 Cu (NO 3) 2 → 1 Cu + 1 Mg (NO 3) 2 Step 6: Final Verification Count the number of atoms of each element on both sides of the equation to verify that it is balanced
[FREE] Balance the chemical equation: 4 Mg + 3 Cu(NO3)2 → 4 Mg(NO3)2 . . . For the reaction in question, the balanced equation should be: 3 Mg (s) + 3 Cu (NO3)2 (aq) → 3 Mg (NO3)2 (aq) + 3 Cu (s) Each element now has the same number of atoms on both sides of the equation, which satisfies the law of conservation of mass
