Answer 1

Answer:

I hope answer is correct

Answer 2

Answer:

$CaCO_3$ and $KNO_3$ has rthorhombic crystal system.

Explanation:

• In the orthorhombic crystal system, all axial (crystallographic) angles are identical. Based on their Rhombic structure the orthorhombic system includes various crystal shapes namely pyramids, double pyramids, rhombic pyramids, and pinacoids. Some common orthorhombic crystals include Topaz, Tanzanite, Iolite, Zoisite, Danburite and more.
• Example of orthorhombic crystal system are Rhombic sulphur, $KNO_3, PbCO_3, CaCO_3, BaSO_4, K_2SO_4$  
• ZnO is a Hexagonal crystal system.
• $H_3BO_3$ is a triclinic crystal system.
