What else can I help you with?
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.
Does copper displace zinc from zinc sulphate?
No, zinc will displace copper from copper sulphate but not the other way around.
What does zinc and water produce?
When zinc reacts with water, it forms zinc hydroxide and hydrogen gas. The reaction rate depends on the presence of acids or other ions in the water.
Which out of carbon dioxide zinc chloride water and hydrogen is not produced from zinc carbonate and dilute hydrochloric?
This is hydrogen.
Why is pure zinc not used to prepare hydrogen gas?
Pure zinc is not used to prepare hydrogen gas because it does not react with water to produce hydrogen gas. Instead, zinc reacts with acids like hydrochloric acid to form zinc chloride and release hydrogen gas. This reaction is utilized in the laboratory to produce hydrogen gas.
Is zinc unreactive to water?
Zinc is unreactive to cold water, but will react with steam to give zinc oxide and hydrogen.
How do you determine the capacity of elements to displace hydrogen?
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.
What would be the word equation be for adding hydrogen gas and zinc sulfate?
hydrogen + zinc sulphate = No Reaction. This is because hydrogen is lower than zinc in the reactivity series and thus cannot displace it
Why does zinc reacts with DI sulfuric acid to give hydrogen gas but not copper?
If you look at reactivity series, you will find zinc to be more reactive than hydrogen while copper being less reactive than it. Therefore zinc is able to displace hydrogen from sulphuric acid while copper is not. The reaction with zinc is:- Zn + H2SO4 -------> ZnSO4 +H2 The reaction with copper is Cu + H2SO4 ---------> No reaction
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.
Will there be a reaction between zinc and water?
Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2
Why copper is not used to prepare hydrogen in the laboratory?
Copper is not typically used to prepare hydrogen in the laboratory because it is not reactive enough to displace hydrogen from water or acids. Other metals like zinc or aluminum are more commonly used for this purpose as they have a higher reactivity with water or acids.
Why does hydrogen form when zinc reacts with hcl?
When zinc reacts with hydrochloric acid (HCl), hydrogen gas is produced because zinc is more reactive than hydrogen. The zinc displaces hydrogen from the acid, resulting in the formation of zinc chloride and hydrogen gas. This displacement reaction is a common reaction in which more reactive metals displace less reactive metals from their compounds.
Which metal will displace hydrogen from an acid?
A metal higher in the reactivity series than hydrogen, such as magnesium or zinc, can displace hydrogen from an acid in a single displacement reaction. The more reactive metal will donate electrons to the hydrogen ions in the acid, forming metal ions and hydrogen gas as products.
Does copper displace zinc from zinc sulphate?
No, zinc will displace copper from copper sulphate but not the other way around.
What does zinc and water produce?
When zinc reacts with water, it forms zinc hydroxide and hydrogen gas. The reaction rate depends on the presence of acids or other ions in the water.
Why does zinc nitrate doesn't react with dilute HCl?
Zinc nitrate does not react with dilute hydrochloric acid (HCl) because zinc is a less reactive metal than hydrogen. In the reactivity series of metals, zinc is placed above hydrogen, which means it is less likely to displace hydrogen in a reaction. Therefore, no reaction occurs when zinc nitrate is combined with dilute HCl.
