Question

Which of the following is a chemical property of liquid water?

Its density is 1.00 g/cm3.
It reacts with sodium metal to form sodium hydroxide and hydrogen gas
It flows.
It freezes to form ice.
It boils at 100°C.

Answer 1

The chemical property of liquid water among the options provided is that it reacts with sodium metal to form sodium hydroxide and hydrogen gas, as this involves a change in chemical composition.

Step-by-step explanation:

The chemical property of liquid water is its reactivity with other substances. Among the options provided, the reaction of water with sodium metal to form sodium hydroxide and hydrogen gas is an example of a chemical property. This is because, during a chemical reaction, the substance (water, in this case) changes its chemical composition and forms new substances (sodium hydroxide and hydrogen gas).

Attributes like density, the ability to flow, freezing to form ice, and boiling at 100°C are physical properties. These properties describe the physical characteristics and changes of state that do not alter the chemical composition of water. For example, when water freezes to form ice or boils to become steam, it is still chemically water (H2O), just in a different state of matter.

Answer 2

B) it reacts with sodium metal to form sodium hydroxide and hydrogen gas

Step-by-step explanation:

B is the only option that show a chemical property, density, freezing, and boiling points are physical properties.
