Question

which of the following properties of ethylene (a ripening agent for bananas) are physical properties, and which are chemical? drag the appropriate items to their respective bins. polymerizes to form polyethylene; 1 l has a mass of 1.260 g under standard conditions; mixes with acetone; odorless; gas at room temperature; flammable

Explanation:

Physical properties can be observed or measured without changing the substance's chemical identity. Chemical properties involve a substance's ability to undergo chemical changes. "1 L has a mass of 1.260 g under standard conditions", "odorless", "gas at room temperature" and "mixes with acetone" are physical as they describe state, smell, mass - volume relationship and solubility without chemical change. "Polymerizes to form polyethylene" and "flammable" are chemical as they involve chemical reactions changing the substance's identity.

Answer:

Physical: 1 L has a mass of 1.260 g under standard conditions, odorless, gas at room temperature, mixes with acetone
Chemical: polymerizes to form polyethylene, flammable
