Which description of salt is a chemical property? no combustion odorless salty taste solid does not conduct electricity

The answer would be:

No Combustion

If you'd like to know why:

Your clue to this is the word "combustion." Combustion is a chemical reaction and chemical properties can only be observed by inducing or creating a chemical reaction. Flammability is a chemical property and this is what is tested in terms of combustion. This is because the reactants in combustion create a new product. The other given properties are all physical properties.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
