3. Indicate if the following compounds will have Polar Covalent bonds. HCl

CH4

H2O

CO

C4H10

CCl4

CCl4

HCl

Explanation:

CCl4 and HCl compounds have polar covalent bonds as chlorine is more electronegative than carbon and hydrogen so there is a partial negative charge on Cl.

the answer is b & c i believe : )

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
