What two things make up a solution, and give an example of each part

Answer 15

Solvent: water, solute: sugar

Question 16

What is a suspension?

Answer 16

When the particles are bigger than the water molecules so it doesn’t dissolve

Question 17

Answer 17

A colloid is when the particles are smaller than suspensions butt bigger than a solute

Question 18

What is the main difference between a colloid and suspensions/solutions

Answer 18

A call Lloyd takes in the water and a solution/suspension tries to take things into the water

Question 24

Define monosaccharide disaccharide and polysaccharide

Answer 24

Mono equals one unit of sugar die equals two units of sugar poly equals many units of sugar

Question 25

What to sugars are isomers and Why

Answer 25
