I think the equation is wrong . Laboratory method receiving of nitrogen dioxide. on left you have 1* Cu, on right you have 1* Cu - good on left you have 1* H, on right you have 2* H - need 1* H on left you have 1* N, on right you have 2* N - need 1* N on left you have 3* O, on right you have 6* O - need 3* O therefore to balance the equation you need to add one H, one N and three O to the left of the arrow. The balanced equation will appear above. For the reaction 3NO2 + H2O 2HNO3 + NO, how many grams of HNO3 can form when 1.00 g of NO2 and 2.25 g of H2O are allowed to react? Enter either the number of moles or weight for one of the compounds to compute the rest. because metals react with acids to form salt and liberate hydrogen gas so infact it should be. 3Cu + 2HNO 3 + 6 H + → 3Cu 2+ + 2NO + 4 H 2 O ); The Gold Parsing System (Hats off! Acido nítrico (HNO3). Reaction stoichiometry could be computed for a balanced equation. So i know the equation looks something like this Cu (s) + HNO3 (aq) ----> Cu(NO3)2 (aq) + NO2 (g) + H2O (l) and i know its a redox reaction with copper the reducing agent and nitrogen the oxidizing agent but i'm having trouble balancing/setting up … Since the sum of individual atoms on the left side of the equation matches the sum of the same atoms on the right side, and since the charges on both sides are equal we can write a balanced equation. Word equation: Copper + Nitric acid → Copper (II) nitrate + Nitrogen dioxide + water. How do you balance this redox equation.
