Web22 okt. 2024 · The balanced chemical equation to represent the reaction is K 2 Cr 2 O 7 + 6 KI + 12 H 2 SO 4 → K 2 SO 4 + Cr 2 (SO 4 ) 3 + H 2 O + 3 I 2 + 6 KOH Hence, 3 moles … Web23 sep. 2024 · First, we must examine the reaction stoichiometry. In this reaction, one mole of AgNO 3 reacts with one mole of NaCl to give one mole of AgCl. Because our ratios are one, we don’t need to include them in the equation. Next, we need to calculate the number of moles of each reactant: 0.123 L × ( 1.00 m o l e 1.00 L) = 0.123 m o l e s N a C l.
