Answer:
A food chain shows how energy is transferred from one living organism to another via food. ... When these animals eat these plant products, food energy and organic compounds are transferred from the plants to the animals.
Answer:
Explanation:
The equation of the reaction is given as:
3H₂ + N₂ → 2NH₃
Given parameters:
Number of moles of NH₃ = 8moles
Number of moles of H₂ = ?
Number of moles of N₂ = ?
Solution
From the balanced reaction equation, we can establish some mole ratios that would help solve the problem:
To find the number of moles of H₂;
The equation shows that:
2 moles of NH₃ were produced using 3 moles of H₂
therefore: 8 moles of NH₃ will be produced by
= 12moles
So, 12 moles of hydrogen gas will react to give 8 moles of ammonia.
To find the number of moles of N₂
The equation shows that:
2 moles of NH₃ were produced from 1 mole of N₂
8 moles of NH₃ would be produced from
= 4moles of Nitrogen gas
Therefore, 4moles of nitrogen gas would be produced
