What would happen to the entropy in the reaction 203(9) ► 302(9)? A. It is impossible to tell.
B. It stays the same.
C. It decreases.
D. It increases.

bez number of particles in reaction increases so randomness or entropy increase.

as entropy is the degree of randomness of particles in a system

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

look at the !

pleaze mark brainliest!
