An element X forms the following compounds with chlorine; XCl4, XCl3, XCl2. This illustrates the
  • A. law of multiple proportions
  • B. law of chemical proportions
  • C. law of simple proportions
  • D. law of conservation of mass
  • E. law of definite proportions
Correct Answer: Option A
Explanation
The law of definite proportions, also known law of definite composition, states that regardless of the amount, a pure compound always contains the same elements in the same proportions by mass.
Law of multiple proportions, also known as Dalton s Law, states that when one element combines with another to form more than one compound, the mass rations of the elements in the compounds are simple whole numbers of each other.
law of conservation of mass: The law of conservation of mass states that the total mass present before a chemical reaction is the same as the total mass present after the chemical reaction; in other words, mass is conserved.
