Calcium carbonate when mixed with water result in the
formation of Calcium hydroxide which is used as an antacid. The chloride ion
also helps in the whitening of teeth thus finding its use as an ingredient in toothpaste.
Iron oxide is dark pigment which is naturally used in
makeup.
<span>Therefore the
answer to this question is
Swap the uses for iron oxide and calcium
carbonate. </span>

The second illustration is the best representation of the change in the movement of particles as the temperature of the water changes.
<u>Explanation:</u>
The second option perfectly represents the boiling of water. As when the temperature is increased, the water molecules gain energy to move faster, thus their kinetic energy of the atoms will be more. This will lead to more freely movement of all the atoms of the water.
And as boiling leads to transformation from liquid state to gaseous state, so the increase in the distance between atoms and molecules occurs in the gaseous state. Thus, the second illustration is best suitable for representing the boiling of water.
As on increasing temperature of the water, the distance between the molecules is increasing in the second illustration while the other illustration shows the decrease in the distance between the molecules. So, the second illustration is the best representation of the change in the movement of particles as the temperature of the water changes.
The correct answer is c, it’s evaporating there for it’s a chemical change
I think it’s Object 3
Hopefully this helps
