2HCl + Cu -> CuCl2 + H2 Assuming that it's Copper (II).
CuCl2=Copper Chloride
Balanced equation: CuO + 2HCl --> CuCl2 + H2O Word equation: One mole of copper (II) oxide plus two moles of hydrochloric acid produces (or yields) one mole of copper (II) chloride plus one mole of water.
I am guessing that you mean hydrochloric acid, and the reaction is ammonia plus hydrochloric acid gives ammonium chloride; NH3 + HCl => NH4Cl
CuO + 2HCl --> CuCl2 + H2O
Magnesium chloride plus hydrochloric acid is magnesium chloride and hydrogen gas.
Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
Balanced equation: CuO + 2HCl --> CuCl2 + H2O Word equation: One mole of copper (II) oxide plus two moles of hydrochloric acid produces (or yields) one mole of copper (II) chloride plus one mole of water.
= Copper(II) chloride + Nitric acid
copper sulphate plus hydrochloric acid
= Copper chloride + water + carbon dioxide
I am guessing that you mean hydrochloric acid, and the reaction is ammonia plus hydrochloric acid gives ammonium chloride; NH3 + HCl => NH4Cl
CuO + 2HCl --> CuCl2 + H2O
Sodium carbonate plus hydrochloric acid gives sodium chloride plus water plus carbon dioxide.
Magnesium chloride plus hydrochloric acid is magnesium chloride and hydrogen gas.
Cu2+ + O2- + H+ + Cl- = Cu2+ + 2 Cl- + H2O
Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
Cu(CO3)2 + 2 HCl ---------- CuCl2 + 2 CO2 + H2O
Sodium hydroxide plus hydrochloric acid equals sodium chloride plus water.
