Question

Which statement is true about water molecules?


Water molecules move randomly around each other.


The hydrogen atoms do not share electrons.


The oxygen atom has a negative charge.


Water molecules cannot dissolve many substances.

Answer 1

Answer:

The true statements are:

Water molecules move randomly around each other.

and

The oxygen atom has a negative charge.

Explanation:

water molecules moves randomly around each other but they will take the shape of any container in which they are present.

The charge on the oxygen atom in water is negative but they have two hydrogen molecules attached to them which have positive charge.

Answer 2

The statement which states that oxygen atom of water molecules is negatively charged is true.

Explanation:

• The bonding of hydrogen and oxygen in water molecules occurs due to the unequal sharing of the electron.
• As oxygen has a strong affinity towards electron, it drags more Numbers of electron towards itself and becomes negatively charged.
• As hydrogen shows less affinity towards electron, it is positively charged.  
• The water is considered as universal solvents, which means that it can dissolve much substances.
