Fundamental Laws Of Chemistry

Question 1

Law of conservation of mass

Answer 1

mass is neither created nor destroyed in chemical reactions

Question 2

Law of Definite Proportions

Answer 2

a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation

Question 3

Law of multiple proportions

Answer 3

When two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers

Question 4

Law of combining volumes

Answer 4

The ratio of the volumes of gases consumed or produced in a chemical reaction is equal to the ratio of simple whole numbers

Question 5

Avogadro’s law

Answer 5

equal volumes of all gases, at the same temperature and pressure, have the same number of molecules

Question 6

Law of mass action

Answer 6

the rate of the chemical reaction is directly proportional to the product of the activities or concentration of the reactants.
