Answer and explanation:
A chemical change occurs when new substances or materials are produced to have different chemical properties from the reactants.
Some examples of this are paper burning, fruit rotting, and metal rusting.
Most solids a) are dense and difficult to compress.
Most solids are closely compacted, their molecules are close together and vibrate. They don't move freely like gas or water molecules do.
They are difficult to be squeezed or flattened.

Answer:
The amount of calcium carbonate will increase.
Explanation:
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
- K>Q , reaction will move forward by making more product.
- K<Q , reaction will move backward by making more reactant.

Equilibrium constant of the reaction = 
Concentration of 
Concentration of 
Concentration of 
![Q=\frac{[CaO][CO_2]}{[CaCO_3]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BCaO%5D%5BCO_2%5D%7D%7B%5BCaCO_3%5D%7D)


This means that equilibrium will move in backward direction by which amount of calcium carbonate will increase.
