Q7. A box contains some identical red coloured balls, labeled as A, each weighirAnother box contains identical blue coloured balls, labelled as B, each weighingConsider the combination AB, AB2, A2B and AB3 and show that law of multipleproportions is applicable. Also state the law. |

Answer» AB mass of A = 2 g mass of B = 5 g hence if mass of A = 1g , mass of B = 5/2 g =2.5inAB2 mass of A = 2g and mass of B= 10g , hence for 1 g A , mass of b = 10/2g =5in A2B , mass of A = 4g , mass of B= 5g , hence for 1 g A , mass of B = 5/4g = 1.25in A2B3 , mass of A = 4 g , mass of B= 15 g , hence for 1 g A mass of B = 15/ 4 g =3.75 therefore ratio ofmass of B in all componds with the same amount of A =2: 4 : 1: 3, which is awhole no. ratio hence law of multiple proportion. Law of multiple proportions, statement that 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. |
