Answer 1

Answer:

The formation of a precipitate

Explanation:

took thecquiz on edge. got it correct

Answer 2

The formation of a precipitate is a evidence that a chemical reaction has likely occurred.

What is Chemical Reaction ?  

A chemical reaction is a process in which chemical bonds between atoms to break and reorganize, to form other new substances.

Evidence of a Chemical Reaction

• formation of precipitate
• a change in color
• formation of a gas
• temperature
• odor change

Now lets check all option one by one

Option (A): a liquid slowly losing volume

Here change in volume occurred which is not a evidence of a chemical reaction.

So it is incorrect option.

Option (B): the formation of a precipitate

Here formation of precipitate is a evidence of a chemical reaction.

So it is correct option.

Option (C): boiling water releasing steam

Here formation of evaporation takes places which is not a evidence of a chemical reaction.

So it is incorrect option.

Option (D): a change in the shape of solid.

Here change in shape occurred which is not a evidence of a chemical reaction.

So it is incorrect option.

Thus, from we can say that the formation of a precipitate is a evidence that a chemical reaction has likely occurred.
