What is the reaction between iron metal and copper (ii) which species is dispalced g

Displacement and redox reaction

Copper is displaced

Explanation:

Iron metal can react with a solution of a salt containing the copper (II) cation, for instance, copper (II) sulfate. This is a displacement reaction.

Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)

Fe is incorporated into the salt, forming iron (II) sulfate and Cu is displaced. This reaction can also be considered a redox reaction because iron is oxidized and copper is reduced.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
