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. ...
Read the law above carefully.
a) NH3, H2O and NO2
These are the SAME element
b) NO, NO2 and N2O5
N and O across the board. These are the same two elements combining with each other. b IS an example
c) CO, CO2 and CH4
CH4 keeps it from the same two elements.
d) H2O, CO2 and CH4
Not same two elements again.
b is an example that follows the law. a, c, d do not follow the law. But I have a problem with the question. a, c and d are not, in my opinion, examples of the law because a, c and d don't have the same two elements.
Which of the following sets of compounds DO NOT follow the law of multiple proportions?
a) NH3, H2O and NO2
b) NO, NO2 and N2O5
c) CO, CO2 and CH4
d) H2O, CO2 and CH4
