Answer:
Malachite
Explanation:
Malachite is a copper carbonate hydroxide mineral, with the equation Cu2CO3(OH)2. This dark, green-joined mineral solidifies in the monoclinic precious stone framework, and frequently shapes botryoidal, sinewy, or stalagmitic masses, in cracks and profound, underground spaces, where the water table and aqueous liquids give the way to synthetic precipitation. So, the answer is malachite. Best of Luck!
Ocean currents determine the various directions of wind movement.
<h3>What is ocean current?</h3>
Ocean currents are caused by differences in density as well as the temperature of the moving winds across the ocean. In the ocean, warm water is found at the top while cooler water occurs far below.
Warm ocean currents originate near the equator and move towards the poles. The ocean currents control the direction of winds in an area.

Answer:
Number of moles of CoCl3 = 0.09 moles
Explanation:
Given data:
Mass of CoCl₃ = 12.1 g
Number of moles = ?
Solution:
First of all we will calculate the molar mass.
Molar mass of CoCl3 = 28.01 + (35.5×3)
Molar mass of CoCl3 = 28.01 + 106.5
Molar mass of CoCl3 = 134.51 g/mol
Number of moles of CoCl3 = mass / molar mass
Number of moles of CoCl3 = 12.1 g/134.51 g/mol
Number of moles of CoCl3 = 0.09 moles
Answer:
To separate an insoluble solid from a soluble solid: Mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid.
