Can hydrogen eliminate copper from gold?
No. hydrogen will eliminate only copper, or gold in the oxidized state, and when dissolved. On 2nd thought, yes. Bring copper and gold into the oxidized, dissolved states, using aquq regia, a solution of 3 parts HCl with 1 part HNO3. Replace spare HNO3 with HCl, using 3 circles of HCl addition and vaporizing. Bubbling hydrogen at this point will free gold and leave copper dissolved
Why HCl doesn't react with copper but H2SO4 does?
HCl does not react with copper because copper is below hydrogen in the reactivity series, which means it is less reactive than hydrogen and cannot displace it from the acid. On the other hand, H2SO4 can react with copper because sulfuric acid is a strong oxidizing agent and can oxidize copper to form copper sulfate and hydrogen gas.
What reaction type is Cu plus Hcl?
The reaction between copper (Cu) and hydrochloric acid (HCl) is a single displacement reaction, where the copper displaces hydrogen from the acid to form copper(II) chloride (CuCl2) and hydrogen gas (H2). This reaction can be represented as: 2HCl + Cu -> CuCl2 + H2.
Why is copper not used to prepare hydrogen by the action of dilute HCL on metal?
Copper is not suitable for preparing hydrogen by the action of dilute HCl because it is less reactive than hydrogen. In a displacement reaction, hydrogen will not be displaced from hydrochloric acid by copper due to its lower reactivity. Other metals that are more reactive than hydrogen, such as zinc or magnesium, are typically used instead.
What type of reaction is Cu plus HCl equals CuCl2 plus 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.

Why copper does not react with hcl?
Copper does not react with hydrochloric acid (HCl) because it is less reactive than hydrogen. It forms a passive layer of copper chloride (CuCl2) on its surface, which protects the copper underneath from further reaction with the acid.
Is there a reaction between hydrochloric acid and and copper?
Yes, a reaction occurs between hydrochloric acid (HCl) and copper (Cu). The HCl will react with the copper to form copper chloride (CuCl2) and hydrogen gas (H2). This reaction is a classic example of a single replacement reaction.
Will cu replace H from H2SO4?
No, copper (Cu) will not replace hydrogen (H) from sulfuric acid (H2SO4) since copper is less reactive than hydrogen. Only metals higher in the reactivity series can displace hydrogen from acids.
What gas is given off when Cu reacts with HCL?
Hydrogen gas is given off when copper reacts with hydrochloric acid (HCl) according to the reaction: Cu + 2HCl -> CuCl2 + H2.
What happens when HCl mixes with heated copper?
When HCl (hydrochloric acid) mixes with heated copper, the copper reacts with the acid to form copper(II) chloride and hydrogen gas. The reaction releases heat and the copper may also appear to be dissolved as it reacts with the acid.
Can magnesium replace after adding into acid?
yes if put into HCl it will replace the H and produce hydrogen gas and magnesium chloride
How many grams of hydrogen is produced when 167.12 g of hydrochloric acid is reacted with copper?
To calculate the grams of hydrogen produced, you need to first balance the chemical equation for the reaction between hydrochloric acid and copper. Once balanced, calculate the moles of hydrochloric acid in 167.12 g, then use stoichiometry to determine the moles of hydrogen produced. Finally, convert the moles of hydrogen to grams using the molar mass of hydrogen (1 g/mol).
