Question

When two elements
combine to form more than
two compounds, then mass of
one element which combine
with the fixed mass of other
element are in simple whole
number ratio is the statement
of *
(a) Law of Reciprocal proportion
(b) Law of Constant composition
(c) Law of Multiple proportion
(d) Law of Combining volumes
​

Answer 1

Answer:

c)law of multiple proportion

Explanation:For example: Hydrogen + Oxygen - water                                                                                      

                                                2g               16g          18g

                                             Hydrogen + Oxygen - hydrogen peroxide

                                               2g                 32g          34g

so here hydrogen combine with oxygen to form two compounds water and hydrogen peroxide where mass of hydrogen in both case is fixed and mass of oxygen is changing. Therefore according to law  ratio of mass of oxygen which is changing is simple whole no. ratio. here we get ratio as 1:2 for oxygen. Therefore ans is c)
