Answer:
mining of clay limestone and then heated to a certain temperature of 1450⁰ in a cement kiln
Explanation:
Noble gases are group O elements and their atomic structure ensures that they are stable. All their orbitals are completely filled with electrons therefore they do not undergo reactions with other elements.
- Heavier noble gases are able to form a range of compounds due their sizes.
- Elements form compounds by exchanging or sharing of their outermost shell electrons called the valence electron.
- Every atom has specific energy required to remove electrons from them. The energy is known as the ionization energy.
- In bigger atoms which have large radius, the outermost electrons have low ionization energy which makes them easy to remove.
- The ionization energy depends on the nuclear charge, the more the charge the higher the ionization energy. Down a group the nuclear charge and ionization decreases.
- As we go down the inert group, the ionization energy of outer shell electrons become very low. This makes the electrons available to take part in chemical reactions.

Talc is not soluble in water, but it is slightly soluble in dilute mineral acids. In any case, solving it will keep intact its structure. This is naturally true for the case of silicates, which are characteristics by their insolubility.
A is milk in water, actually is does not have to be in water since milk already is a mixture of fats and water. ... A colloid is just a mixture where a substance of dispersed insoluble particles is suspended throughout another substance. Chalk powder is very little soluble in water therefore this will form an suspension.
Ice is the solid phase of water, so it is not silicate.
The answer to your question is the option D, it moves crust plates around
