Hydrogen is very reactive with most elements______
Hydrogen is the least dense of all elements______

Answer 1

Answer:

physical

chemical

chemical

physical

Explanation:

Answer 2

Answer:1. physical property.  

2. chemical property.

3. chemical property.

4. physical property.

Explanation:

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.

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.

1. Hydrogen is a colorless, tasteless, and odorless gas : physical property as there is no change in chemical composition

2. Hydrogen is very combustible in the presence of oxygen :chemical property as there is a change in chemical composition

3. Hydrogen is very reactive with most elements :chemical property as there is a change in chemical composition

4. Hydrogen is the least dense of all elements : physical property as there is no change in chemical composition
