A scientist kept 1,000 gram samples of radioactive carbon, radium, and plutonium in three different containers. The table below shows the half-lives of the three radioactive materials.
Radioactive Material
Half-life (in years)
carbon
5,700
radium
1,620
plutonium
6,563
Based on the table, which of these conclusions is most likely correct? (1 point)
After 6,000 years, approximately 250 grams of carbon and radium will be left in the containers.
O After 20,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.
After 6,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.
After 20,000 years, approximately 250 grams of carbon and radium will be left in the containers,

asking the goog might u get an answer

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

um i think it might be a car?
