Without calculating any frequency values, select the highest frequency transition in the hydrogen atom. a) from n = 4 to n = 6
b) from n = 6 to n = 8
c) from n = 9 to n = 11
d) from n = 11 to n = 13

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

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

the answer is c i took the test
