Write the molecular formulas of food salt, hydrogen sulfide, iodine and oxygen, determine the types of their chemical bonds and characterize their properties
NaCl – sodium chloride (food salt), chemical bond – ionic. Solid under normal conditions.
H2S – hydrogen sulfide, chemical bond – covalent polar. Under normal conditions, gas with an unpleasant odor is heavier than air.
I2 – iodine, chemical bond – covalent non-polar. Under normal conditions, a solid exhibits metallic properties.
О2 – oxygen, chemical bond – covalent non-polar. Under normal conditions, the gas is odorless and colorless, heavier than air.
