Question

In the following chemical equation:

$xFe\:+\:yO_2\Rightarrow\:zFe_2O_3$ values of coefficient x, y & z after balancing, should be:


a) x = 2, y = 3 , z = 4 c) x = 4 , y = 3, z = 2


b) x = 4 y = 2 , z = 3 d) x = 2 y = 4, z = 3

Answer 1

Answer:

OPTION C:

x = 4

y = 3

z = 2

Explanation:

The given skeletal (unbalanced) equation is:

$Fe + O_2 ---> Fe_2O_3$

The balanced equation is

$4Fe + 3O_2 ---> 2Fe_2O_3$

The values of x, y and z will be:

x = 4

y = 3

z = 2
