Question

reasons that diffusion of a chemical is fastest in air than water. diffusion of a chemical is faster in air than in water because (select all that apply) check all that apply the chemical would have to collide with and push through fewer molecules as it spreads out. water is polar. air molecules travel faster than water molecules. air molecules are smaller than water molecules. air is less dense than water.

Explanation:

Diffusion rate depends on the medium's density and molecular - related factors. Air is less dense than water, so a chemical has to push through fewer molecules. Also, air molecules generally move faster than water molecules. Water's polarity is not directly related to the faster diffusion in air, and the size of air molecules compared to water molecules isn't the main factor for this difference in diffusion rates.

Answer:

• the chemical would have to collide with and push through fewer molecules as it spreads out.
• air molecules travel faster than water molecules.
• air is less dense than water.
