The capacity of elements to displace hydrogen can be determined based on their position in the reactivity series. Elements higher in the reactivity series can displace hydrogen from compounds of elements lower in the series. For example, metals like magnesium and zinc can displace hydrogen from water because they are higher in the reactivity series.

Why does copper does not displace hydrogen from dilute acid violently?
Copper is less reactive than hydrogen, so it does not displace hydrogen from dilute acid violently. The reactivity series shows that copper is lower in the series than hydrogen, meaning it is less likely to displace hydrogen in a chemical reaction.
Why lead is not used for the preparation of hydrogen from dilute HCL or dilute sulphuric?
Lead is not reactive enough to displace hydrogen from dilute HCl or dilute sulfuric acid. The reduction potential of lead is lower than that of hydrogen, so it cannot effectively displace hydrogen in these reactions. Other metals like zinc or aluminum are used instead due to their higher reactivity and ability to displace hydrogen.
Why does copper and hydrochloric acid not react?
Copper does not react with hydrochloric acid because it is not reactive enough to displace hydrogen from the acid. Copper is below hydrogen in the reactivity series, so it cannot displace hydrogen ions to form copper chloride and hydrogen gas.
What are elements on an alcohol?
There are at least carbon, hydrogen and oxygen atoms on an alcohol molecule.
How can one determine if an acid is strong or weak based on its formula?
One can determine if an acid is strong or weak based on its formula by looking at the presence of certain elements and the number of hydrogen atoms attached to those elements. Strong acids typically have hydrogen attached to highly electronegative elements like oxygen or halogens, while weak acids have hydrogen attached to less electronegative elements like carbon. Additionally, the number of hydrogen atoms attached to the acidic element can also indicate the strength of the acid, with more hydrogen atoms typically indicating a stronger acid.
Does zinc displace hydrogen from cold water?
Zinc does not displace hydrogen from cold water, as zinc is lower in the reactivity series than hydrogen. However, if zinc is reacted with an acid, such as hydrochloric acid, it will displace hydrogen gas.
Why does copper does not displace hydrogen from dilute acid violently?
Copper is less reactive than hydrogen, so it does not displace hydrogen from dilute acid violently. The reactivity series shows that copper is lower in the series than hydrogen, meaning it is less likely to displace hydrogen in a chemical reaction.
Can magnessium displace hydrogen?
Yes.
What metal cannot displace hydrogen from dilute acid?
Gold is a metal that cannot displace hydrogen from dilute acid due to its low reactivity.
Which element can displace other elements from the compounds?
A more reactive element can displace a less reactive element from a compound, according to the reactivity series. For example, metals like magnesium and zinc can displace hydrogen from water or acids.
Why lead is not used for the preparation of hydrogen from dilute HCL or dilute sulphuric?
Lead is not reactive enough to displace hydrogen from dilute HCl or dilute sulfuric acid. The reduction potential of lead is lower than that of hydrogen, so it cannot effectively displace hydrogen in these reactions. Other metals like zinc or aluminum are used instead due to their higher reactivity and ability to displace hydrogen.
Why most of the transition metal not displace hydrogen in acid?
Most transition metals do not displace hydrogen in acid because they are not reactive enough to displace hydrogen from acids. Transition metals tend to form stable compounds with acids instead of displacing the hydrogen. This is due to their high ionization energies and tendency to form complex ions.
What are elements on an alcohol?
There are at least carbon, hydrogen and oxygen atoms on an alcohol molecule.
Why does copper and hydrochloric acid not react?
Copper does not react with hydrochloric acid because it is not reactive enough to displace hydrogen from the acid. Copper is below hydrogen in the reactivity series, so it cannot displace hydrogen ions to form copper chloride and hydrogen gas.
Can copper be used to prepare hydrogen by reaction with diluteacids?
No. Copper is below hydrogen in the electromotive series and therefore can not displace hydrogen from its compounds.

Why does potassium displace hydrogen ions from both acids and water?
Potassium is more reactive than hydrogen, which allows it to displace hydrogen from acids like many other metals. Unlike most metals it is reactive enough to pry away the more strongly-bonded hydrogen in water.
