Law of conservation of mass can be derived from which postulate of Dalton's atomic theory?
Atoms of a given element have same mass and chemical properties.
Matter is made of tiny particles.
The relative number and kind of atoms are constant in a given compound.
Atom can neither be created nor destroyed.
According to the law of conservation of mass, mass can neither be created nor destroyed in a chemical reaction.
Which of the following are true according to Dalton’s Atomic Theory?
(i) Atoms can neither be created nor destroyed in a chemical reaction.
(ii) Atoms of different elements have different masses and chemical properties.
(iii) Atoms can be broken down into smaller parts like Protons,Electons And Neutons .
(iv) Atoms of an element have variable chemical properties depending on the Chemical reactions
(v) The relative number and kinds of atoms vary in a given compound.
(vi) Atoms combine in the ratio of small whole numbers to form Compounds.
Law of conservation of energy states that elements can neither be created nor destroyed.
