1.	Hydrogen and oxygen are known to from two compounds. The hydrogen content in one one of these is 5.93% while in the other it is 11.2%. Show that this data illustrates the law of multiple proportions.
Answer» In the first compound Hydrogen = 5.93 % Oxygen = `(100-5.93)% = 94.07 %` In the second compound Hydrogen = 11.2 % Oxygen `= (100-11.2)%=88.8%` In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen `=(94.07)/(5.93)=15.86` parts In the second compound the number of part by mass of oxygen that combine with one part by mass of hydrogen `=(88.8)/(11.2)=7.9` parts. The ratio of masses pf oxygen that combine with fixed mass (1 part) by mass of hydrogen is 15.86 : 7.9 or 2 : 1. Since this ratio is a simple whole number ratio, hence the given data illustrates the law of multiple proportions.

Which of the following statements is correct about the reaction given below:- `4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`A.
