What is the net ionic equation for 2HNO3(aq) + Ca(OH)2(aq) --> Ca(NO3)2(aq) + 2H20(l)

k

explanation:

k

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

14 days is the half-life of phosphorus-32

it is stable as it is in group 0 which have full outer shells of electrons
