A 2.0 mL sample of air in a syringe exerts a pressure of 1.02 atm at 22 C. If that

The new volume of the air in the syringe is 7.3 mL.

Explanation:

Given: = 2.0 mL,     = 1.02 atm,          

= ?,               = 1.27 atm,              

Formula used to calculate the new volume in syringe is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the new volume of the air in the syringe is 7.3 mL.

The scenario, which is likely a chemical reaction is this: TWO COLORLESS LIQUIDS ARE ADDED TOGETHER, AND A COLORLESS LIQUID AND A GREEN SOLID REMAIN.

A chemical reaction is said to occur when two or more element combine together chemically so that a new substance is formed as product. Chemical reactions are typically irreversible and the products formed have properties that differ from the properties of the reactants. Looking at the options given above, it is only in option 4 that a new substance is formed, which is a green precipitate. Thus, option 4 showcase a chemical reaction.
