Given the following chemical equation, determine how many grams of N2 are produced by 9.24 of H2O2 nd 6.56g of N2H4?
valkas [14]
The balanced chemical equation will b
N2H4 + 2 H2O2-> N2 + 4H2O
 so first of all we have to find the limiting reactant.
so for this 

9.24 g H2O2 ( 1 mol / 34.02 g mass of H2O2 )
 = 0.27 mol H2O2
Now
6.56  g of  N2H4 ( 1mol / 32.06) = 0.20 mol N2H4

so from the above reaction we found 1:2 ratio of the reactants
 so the limiting reactant is hydrogen peroxide. by using this we will find the amount of N2 produced.
so that will be

<span>0.27 mol H2O2 ( 1 mol N2 / 2 mol H2O2 ) ( 14.01 g N2 / 1 mol N2)
 =1.89 g N2
hope it helps</span>

What will happen if a crystal of ammonium nitrate is added to a supersaturated ammonium nitrate solution? Will it dissolve in wa
romanna [79]

Answer:

It will not dissolve. More crystals will separate from the solution.  

Step-by-step explanation:

If you add a crystal of ammonium nitrate to a supersaturated solution of the solute, it will not dissolve.  

Instead, it will act as a "seed" on which more ammonium nitrate crystals will form.

They will separate from the solution as long, colourless, needle-like crystals until the solution is no longer supersaturated.
