To dazzle his students, Mr. Turner collected volumes of ammonia gas and carbon dioxide gas. As the two colorless gases were combined in a closed two-liter bottle with a small amount of ammonium hydroxide, the chemistry students watched in amazement at the growth of white crystals inside the bottle. What happened inside the bottle as the gases were mixed? A) a physical change B) a chemical change C) the solution process D) a mixture was formed

B) a chemical change .

Explanation:

There will be no chemical reaction when the gases ammonia and carbon dioxide are mixed together . But when there is presence of ammonium hydroxide , chemical reaction takes place between carbon dioxide and ammonium hydroxide resulting into the formation of ammonium carbonate  as follows

2NH₄OH + CO₂ =( NH₄)₂CO₃  + H₂O.

The growth of white crystals inside the bottle indicates the presence of ammonium carbonate .

So it is a chemical change .

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
