Copper (Cu) is below hydrogen (H) in the activity series of metals, which means it is less reactive than hydrogen. As a result, when copper is placed in dilute sulfuric acid (H2SO4), it is unable to displace hydrogen from the acid to liberate H2 gas. Only metals above hydrogen in the activity series can displace hydrogen from acids to form hydrogen gas.
Hydrogen gas is given off when copper reacts with hydrochloric acid (HCl) according to the reaction: Cu + 2HCl -> CuCl2 + H2.
CuSO4 Cu + 2H2SO4 -> CuSO4 + SO2 + 2H2O
When copper reacts with hydrochloric acid (Cu HCl), it forms copper chloride (CuCl2) and hydrogen gas (H2).
Cu + 2 HCl = CuCl2 + H22 Cu + 2 HCl = 2 CuCl + H2
2HCl + Cu -> CuCl2 + H2 Assuming that it's Copper (II). CuCl2=Copper Chloride
When zinc (Zn) is added to dilute sulfuric acid (H2SO4), zinc sulfate (ZnSO4) and hydrogen gas (H2) are produced. The chemical reaction can be represented as: Zn + H2SO4 -> ZnSO4 + H2.
Hydrogen gas is given off when copper reacts with hydrochloric acid (HCl) according to the reaction: Cu + 2HCl -> CuCl2 + H2.
Cu(NO3)2 and H2 are formed
CuSO4 Cu + 2H2SO4 -> CuSO4 + SO2 + 2H2O
In the reaction involving copper(II) oxide (CuO) and hydrogen gas (H2), hydrogen acts as a reducing agent. The hydrogen reduces CuO to metallic copper (Cu), while itself being oxidized to form water (H2O). This process involves the transfer of electrons, where CuO gains electrons to form Cu, and H2 loses electrons to form H2O. Overall, the chemical reaction can be summarized as: CuO + H2 → Cu + H2O.
When copper reacts with hydrochloric acid (Cu HCl), it forms copper chloride (CuCl2) and hydrogen gas (H2).
(Cu)s + 2HNO3 --> Cu2+ + 2NO3- + (H2)gas
Cu + 2 HCl = CuCl2 + H22 Cu + 2 HCl = 2 CuCl + H2
2HCl + Cu -> CuCl2 + H2 Assuming that it's Copper (II). CuCl2=Copper Chloride
The correct answers are: Ag+ and Cu+2.
When copper (Cu) is added to hydrochloric acid (HCl), a chemical reaction occurs where the copper reacts with the hydrochloric acid to form copper chloride (CuCl2) and hydrogen gas (H2). This reaction is represented by the following equation: 2HCl + Cu -> CuCl2 + H2.
The reaction between copper (Cu) and hydrochloric acid (HCl) to form copper(II) chloride (CuCl2) and hydrogen gas (H2) is a single displacement reaction. This is because the copper replaces the hydrogen in HCl to form CuCl2.
