If a chemical reaction occurred, write a balanced equation for it. Then using the A, B symbols, write a general equation for a single-displacement reaction. Here are the chemical formulas of the reactants for each reaction: †¢ zinc – Zn copper sulfate – CuSO4 In well 1A there was a chemical reaction which turned†¦show more content†¦Then using the A, B symbols, write a general equation for a double-displacement reaction. Here are the chemical formulas of the reactants for each reaction: †¢ sodium chloride – NaCl copper sulfate – CuSO4 In well 1A there was no chemical reaction between the sodium chloride and copper sulfate. We know this because there was no color change, precipitate formation, or gas production in this mixture. AX + BY → AY + BX NO REACTION †¢ sodium hydroxide – NaOH copper sulfate – CuSO4 In well 2A there was a chemical reaction between the sodium hydroxide and copper sulfate. There was a blue precipitate formation which proves there was a chemical reaction. AX + BY → AY + BX NaOH + CuSO4 → NaSO4 + CuOH †¢ sodium phosphate (trisodium phosphate) – Na3(PO4) copper sulfate – CuSO4 In well 3A there was a chemical reaction between the sodium phosphate and copper sulfate. There was a light blue precipitate formation which proves there was a chemical reaction. AX + BY → AY + BX Na3(PO4) + CuSO4 → Na3SO4 + CuPO4 †¢ sodium chloride – NaCl silver nitrate – AgNO3 In well 4A there was a chemical reaction between the sodium chloride and silver nitrate. There was a white precipitate formation which proves there was a chemical reaction. AX + BY → AY + BX NaCl + AgNO3 → NaNO3 +
