Question

Tetrachloromethane, CCl4, is classified as a

(1) compound because the atoms of the elements are combined in a fixed proportion
(2) compound because the atoms of the elements are combined in a proportion that varies
(3) mixture because the atoms of the elements are combined in a fixed proportion
(4) mixture because the atoms of the elements are combined in a proportion that varies

Answer 1

Tetrachloromethane, CCI4, is classified as a compound because the atoms of the elements are combined in a fixed proportion.

Answer 2

Correct Answer: compound because the atoms of the elements are combined in a fixed proportion.

Reason:
A chemical compound is a chemical substance composed of element (of same or different type) that are bonded in a fixed proportion. Depending upon the type of element, bond can be ionic or covalent. In present case, tetrachloromethane i.e. CCl4 has one 'C' atom that is covalently bonded to four 'Cl' atoms.
