Question

The valency of element x is 3 and that of element is Y is 4. Write down the formula formed between X and Y

Answer 1

Answer:   x4y3

Explanation:

we have to cross multiply the valencies and their elements.

eg:      h               o

          1                 2

thus, the formula is h20

(by multiplying h with 2 and o with 1).

similarly, x(4) and y(3) will be obtained after cross multiply.

hence, ans=x4y3
