Write balanced chemical equations for the reactions used to prepare each of the following compounds from the given starting material(s). In some cases, additional reactants may be required. solid ammonium nitrate from gaseous molecular nitrogen via a two-step process (first reduce the nitrogen to ammonia, then neutralize the ammonia with an
Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Na2HPO4 + 12 (NH4)2MoO4 + 23 HNO3 = (NH4)3(PMo12O40) + 21 NH4NO3 + 2 NaNO3 + 12 H2O. Reactants. Products. To balance the equation HNO3 + NaHCO3 = NaNO3 + H2O + CO2 using the algebraic method step-by-step, you must have experience solving systems of linear equations. Create an equation for each element (H, N, O, Na, C) where each term represents the number of atoms of the element in each reactant or product. H: 1 a + 1 b = 0c + 2 d + 0f N:Balanced equation. 3Cu (s) + 8HNO 3(aq) → 3Cu(NO 3) 2(aq) + 2NO (g) + 4H 2 O (l) Nitric oxide is a colorless gas and oxidation number of nitrogen is +2. So oxidation number of nitrogen is reduced from +5 to +2 while oxidation number of copper is increased from 0 to +2. Nitric oxide is a neutral gas.
Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of Al (NO3)3 + 3NaOH = Al (OH)3 + 3NaNO3, the equation is balanced. Balance the reaction of Al (NO3)3 + NaOH = Al
Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of HI + NaOH = NaI + H2O, the equation is balanced. Balance h7rDW. 169 225 210 433 5 299 138 410 495
