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.

answer to this question is
Swap the uses for iron oxide and calcium
carbonate. </span>

- The answer is shorter wavelength and equal speed.
That is, compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have shorter wavelength and equal speed.
This can be seen by the reaction given below:
h= Planck's constant
c=speed of the light
=frquency
=wavelength
So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.
The answer is C :
It controls the entry and exit of substances.
Answer:
P and V: inversely proportional
P and T: directly proportional
V and T: inversely proportional
Explanation:
For pressure and volume, as the volume goes up, meaning the container gets bigger, the pressure would go down. There would be more room in the container, so there would be less collisions between the molecules themselves and between the molecules and the container. This makes them inversely proportional.
For pressure and temperature, as the pressure goes up, there are more collisions, so the particles move faster. Temperature is the speed of the particles, so, since both pressure and temperature would go up at the same time, they are directly proportional.
For volume and temperature, this is similar to the PV relationship. As volume increases, there are less collisions between the particles. This means that the particles are going to move slower. Therefore, as volume goes up, temperature goes down, so they are inversely proportional.
Sorry this is super long, but I hope it fully explains the question for you! ☺
I believe the answer to your question is none of the above
