How is the earth like a gigantic recycling center
Answer: The earth is like a recycling center because as things are being used other organisms can use their waste to live.
Explanation: The cycle is cyclic allowing for the cycle to never end unless things are destroyed.
A reaction vessel for synthesizing ammonia by reacting nitrogen and hydrogen is filled with 6.04 kg H2 and excess N2. If 28.0 kg NH3 is produced, what is the percent yield of the reaction?
The balanced equation for the reaction is ⇒
So to find the number of moles of we do 6.04kg ÷ 2 = 3.02 moles.
The mole ratio between and is 3:2. So to find the number of moles you do × 2 which gives you 2.0124 moles.
Then you find the mass by doing moles multiplied by Mr: 2.0124 x 17 which gives you 34.21 kg.
Then to find the percentage yield you do: x 100 = 81.82.......
Which is 81.8 %

What differs between a radioactive isotope and a stable isotope? A. Radioactive isotopes last longer. B. Radioactive isotopes last for less time. C. There is no difference. D. Stable isotopes are shorter.
B. Radioactive isotopes last for less time, is the one that makes the most since of the following options in the question above it shows the way a radioactive isotope and a stable isotope differs. A radioactive isotope lasts for less time because it is not stable.
