Red #40 is soluble in water while zinc oxide is not.
So the easiest way to separate them is as follows:
1- add water to the mixture until red #40 is dissolved in the water
2- filter to separate the zinc oxide
4- heat the solution of red #40 and water until water evaporates and red#40 remains.
Answer: 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.
Explanation:
The balanced chemical reaction is :
According to stoichiometry:
1 mole of react with = 3 moles of
30.479 moles of will react with= of
Mass of =
Thus 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.
