Question

Which one of the following statements about atoms is True?

Select one:

Most of our body weight is due to the presence of carbon atoms in our body

Carbohydrates and fats are made up of different types of atoms

Some oxygen atoms are destroyed to make room for less abundant atoms in the body

The hydrogen atoms in a water molecule weighs less than the oxygen atom

A carbon atom can be converted to an oxygen atom

Answer 1

Ans:- The hydrogen atoms in a water molecule weighs less than the oxygen atom is true.

Because,

# Most of our body weight is due to oxygen atom not carbon.

# Carbohydrates are made up of same types of atoms that is hydrogen, oxygen and carbon.

# Some oxygen atoms are destroyed to make room for less abundant atoms in the body is wrong.

# The hydrogen atoms in a water molecule weighs less than the oxygen atom is true. Because in water molecule weight of hydrogen is 2g while weight of oxygen is 16g.

# A carbon atom can be converted to an oxygen atom is wrong.
