Question

When elements react, their atoms combine in :

• A. a simple whole number ratio (unique for each pair of elements)
• B. arbitrary proportions
• C. simple whole number ratios (more than one possible)
• D. 1:1 ratios

Answer 1

Answer: (C)

simple whole number ratios (more than one possible)

The law of multiple proportions state that if two elements form more than one compound between them then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.
