list. Check all of the boxes that apply.
gas at room temperature
strong, unpleasant odor
reacts with hydrochloric acid
dissolves easily in water
burns in oxygen

Answer 1

Answer: gas at room temperature , strong, unpleasant odor, dissolves easily in water

Step-by-step explanation:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.

a) gas at room temperature: As the state is described here, it is a physical property

b) strong, unpleasant odor: As there is no chemical change, it is a physical property

c) reacts with hydrochloric acid:
`NH_3+HCl\rightarrow NH_4Cl` : As there will be a chemical change, it is a chemical property

d) dissolves easily in water: As there is no chemical change, it is a physical property

e) burns in oxygen:
`4NH_3+3O_2\rightarrow 2N_2+6H_2O` : As there will be a chemical change, it is a chemical property
