Which formulas represent compounds that are isomers of each other? h hh-c-h and h c-hh h2 ho-c-h and h c-ohh hh-c-c-c oh and h-c o-c-c-hh hh h hoh hh oh h4 h-c-c-c-h and h c c-hh h

Answer : The correct option is, (3)

Explanation :

Isomers : It is defined as the molecule that has the same chemical formula but  it has the different structures.

Same chemical formula means that the same number of elements are present in both the compounds.

In option 1,2 and 4, both chemical formula and the structure are different. So, the option 1 compounds are not the isomers of each other.

In option 3, the chemical formula is same but the structure are different. So, the option 3 compounds are the isomers of each other.

Hence, the correct option is, (3)

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 is a and have a great day
