1)first write chemical formula in words

2)then write the formula

3)check the formula whether the coefficients are correct

4)finnaly verify the formula

1)

*Hit & Trial method-*We just have to put any coefficient before any compound & try to equate to opposite side of that element or compond.

2)

*Algebraic expression method-*We 1st have to put coefficient a,b,c,d,e........& on till how many componds are given both on left hand side & right hand side.Then we have to put the value of a=1 & with respect to a particular element we have to make an equation.Thus, like this we have to find out all the values of a,b,c,d,e......& on.
