Answer : The correct option is (B).

Explanation :

Isomer : It is defined as a molecule have the same molecular or chemical formula but the different chemical structure or shape.

The given compound has 4 carbon atoms and also saturated compound because there is no double or triple bond present.

As we know that there are two structural isomers of butane.

(1) n-butane

(2) iso-butane

Thus, the correct option is (B).

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

the answer would be a
