What happens when one adds (NH4)2S to a solution that contains Al3+? What are the products of the chemical reaction?

What happens when one adds (NH4)2S to a solution that contains Al3+?

Explanation:

When a solution that contains reacts with ammonium sulfide solution, then a precipitate of aluminum sulfide is formed.

The chemical equation for the reaction is shown below:

answer: a chemical reaction

explanation:

im not wrong

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
