Reacting copper(II) oxide with sulfuric acid - RSC Education

WebA change in which one or more new substances are formed is known as chemical change. For Example, when the iron is exposed to air and moisture, rust formation takes place. Rust is nothing but Iron Oxide; a new substance formed out of the reaction. The colour of the surface of the iron also changes. Hence, rusting of iron is a chemical change. Web(b) Mixing two solutions produces insoluble particles. (c) Mixing two colorless solutions gives a yellow solution. (d) Mixing two solutions produces a temperature increase. What are four observations that a chemical reaction has occurred? Answers: (a) a gas is released; (b) a precipitate is produced; (c) a permanent color change is observed; WebIn this case, the copper chloride (CuCl2) reacts with water to form copper oxide (CuO) and hydrochloric acid (HCl): CuCl2 + H2O → CuO + HCl Both the copper oxide and the hydrochloric acid are different from the water and copper chloride, so it’s a chemical change.
