How do you balance #NO_3^(-) + 4H^+ + Pb -> Pb^(2+) + NO_2 + 2H_2O#? How do you balance this thermite reaction: #?Fe_2O_3(s) + ?Al(s) -> ?Fe(s) ?Al_2O_3(s)#? Check that an ionic equation is balanced for the charge by seeing if all the positive and negative charges cancel each other out on each side of the equation. Chemical Reaction: Science Unit … I thought group 2 metals only made oxides when they burned in oxygen. Which of the equations below is an example of a thermochemical equation a Mg plus 2H3O plus plus Cl- --- Mg2 plus plus 2Cl- plus H2 plus h20 b 2H2 G plus 2O2 G ----H2O g plus 483.6kj c 2H2 G plus 2O2? Br = Br-1 charge. write a balanced equation for the reaction of the magnesium and the oxygen, 3(s), reacts when strongly heated with magnesium powder to give a mixture of magnesium oxide and magnesium boride, Mg 3B 2(s).
