Please answer the multiple choice down below

1. If there is more solute (salt, sugar, ions) outside of a cell, and the cell membrane is not permeable to any of the solutes, what is likely to happen?

water will enter the cell

water will leave the cell

solutes will enter the cell

solutes will leave the cell

2. When two gases diffuse towards each other down a long tube, and somewhere in the tube a white ring forms, you can conclude that...

a chemical reaction has taken place between the gases

someone forgot to clean the tube

the gases are inert

the gases were actually unable to diffuse

3. If two gases of unequal molecular mass diffuse towards one another in a closed glass tube, they are more likely to react in which part of the glass tube?

the gases would meet in the middle and react

the gases would meet closer to the start of the light gas and react

the gases would meet closer to the heavy gas and react

the gases would never react
