• Glucose (C6H12O6)

• Water (H2O)

What are the main differences between organic and inorganic compounds?

• Organic compounds contain carbon and are typically found in non-living things, while inorganic compounds do not contain carbon and are often found in living organisms.

• Organic compounds do not contain carbon and are often found in non-living things, while inorganic compounds contain carbon and are typically found in living organisms.

• Organic compounds contain carbon and are typically found in living organisms, while inorganic compounds do not contain carbon and are often found in non-living things.

• There are no differences between organic and inorganic compounds.

Explain the formation of an ionic bond.

• An ionic bond is formed through the transfer of electrons between atoms.

• An ionic bond is formed through the attraction of protons between atoms.

• An ionic bond is formed through the sharing of electrons between atoms.

• An ionic bond is formed through the repulsion of electrons between atoms.

Describe the formation of a covalent bond.

• Two atoms share protons

• Two atoms share one or more pairs of electrons

• Two atoms share electrons in different energy levels

• Two atoms share neutrons
