Question

A scientist is working with methane (CH4) and butane (C4H10). Which statement best compares these chemicals?

Answer 1

its is c i just did it in ed

Answer 2

Answer : The correct option is, They are compounds made of the same two elements, but each contain different numbers of atoms.

Explanation :

The methane and butane is a hydrocarbon in which the carbon and hydrogen are bonded through covalent bond. Methane and butane are the homologous series of alkane.

Methane and butane are the compounds which is made up of the same elements but each of the compound contains different number of atoms.

In methane $(CH_4)$, there are 4 number of hydrogen atoms and 1 number of carbon atom.

In butane $(C_4H_{10})$, there are 10 number of hydrogen atoms and 4 number of carbon atoms.

Hence, the best statement is, they are compounds made of the same two elements, but each contain different numbers of atoms.
