<u><em>Displacement reactions:
</em></u><em>it is the type of reaction in which reaction starts with the help of two compounds,,, but in the product the reactant that was initially with 1st compound joins with the 2nd compound..
</em><em> A+BC</em>⇒<em>AC+B
<u>example:
</u>Fe+CuSO4</em>⇒<em>Cu+FeSO4</em><em>
</em><u><em>Double displacement reactions:
</em></u><em>while it is the type of reaction in which one product is obtained parts of both reacting compounds interchange with each other..
</em><u><em></em></u><em> AB+CD</em>⇒<em>AD+BC</em><em>
<u>example:
</u>AgNO3+NaCl</em>⇒<em>AgCl+NaNO3.....:)</em><em><u>

b. growth in the size of the mineral grains
Explanation:
Non-foliated texture shown by a metamorphic change is depicted by growth in the size of the mineral grains.
- Examples of non-foliated metamorphic rocks are quartzite and marble.
- In these metamorphic rocks, mineral grains are not aligned with their long axis.
- Non-foliated texture occurs under high temperature and low pressure conditions.
- As minerals are able to grow, the size can be used to show a metamorphic change.
Answer:
Covalent solids, also called network solids, are solids that are held together by covalent bonds. As such, they need localized electrons (shared between the atoms) and therefore the atoms are arranged in fixed geometries. Distortion far from this geometry can only occur through a breaking of covalent sigma bonds.
