Reactivity is not a physical property because it's a characteristic of a chemical element or compound and is involved in chemical process.
<span>Hydrogen can be obtained economically as a byproduct in the electrolysis of "brine".

A solution of sodium chloride (NaCl)and water (H2O) refers to the brine.The procedure of electrolysis includes utilizing an electric current to achieve a synthetic change and make new chemicals. The electrolysis of brine is a huge scale process used to make chlorine from salt, so three important chemicals, NaOH, Cl2, H2, can be gotten by electrolyzing brine.
From each drop-down menu, a solid has (a definite volume and a definite shape), a Liquid has (a definite volume) and gas has ( non of the above)
<h3>The features of different states of Matter:</h3>
Matter is defined as anything that has weight and occupies space.
There are three states of matter that is in existence which include:
- Solid: The particles of solid are closely packed together and vibrate around fixed axes. That is why they have a definite shape and volume.
- Liquid: The particles of liquid, though attracted to each other,move freely over each other. That is why they have definite volume but not a definite shape.
Therefore, a liquid occupies the shape of its container.
- Gas: The particles of gas contain scattered molecules that are dispersed across a given volume.
Therefore, a gas neither has a definite shape nor volume.
