Question

The list below includes some of the properties of
ammonia. Identify the physical properties in the
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

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

Answer 2

The physical properties of ammonia are gas at room temperature, strong & unpleasant odor and dissolves easily in water.

What are physical properties?

Physical properties are those properties which are happen due to change in the structural behavior of the substance but having the same original properties after change also.

• Gas at room temperature: It is a physical property because it tells about the appearance of ammonia gas.

• Strong, unpleasant odor: It also tells about the physical property because no chemical change is involved.
• Reacts with hydrochloric acid: Reaction of ammonia with hydrochloric acid produces ammonium chloride, because of the changes in chemical properties.

        NH₃ + HCl → NH₄Cl

• Dissolves easily in water burns in oxygen: Dissolution of ammonia in water is also an example of physical change because no change in chemical property observes.

Hence gas at room temperature, strong & unpleasant odor and dissolves easily in water are examples of physical changes.
