Answer 1

Answer:

1. water and salt

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

2. sugar and water

When you stir a spoonful of sugar into a glass of water, you are forming a solution. This type of liquid solution is composed of a solid solute, which is the sugar, and a liquid solvent, which is the water. As the sugar molecules spread evenly throughout the water, the sugar dissolves.

3. water and sand

When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water.

4. water and sawdust

the sawdust most likely will float in water
