Using the balanced equation N2+O2=2NO, how many grams of NO can be produced when 25.0 grams of N react?
Oxana [17]

Answer:

53.55gNO

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

=25.0gN_2*\frac{1molN_2}{28.02gN_2}*\frac{2molNO}{1molN_2}*\frac{30.01 gNO}{1molNO}\\\\=53.55gNO

Best regards!

How many moles of O2 would be needed to produce 3.2 moles Fe2O3?
antiseptic1488 [7]

Answer:

0.533 mol O2

Explanation:

4 Fe3O4 + O2 -> 6 Fe2O3

1 mol O2  -> 6 mol Fe2O3

           x   -> 3.2 mol Fe2O3

x = (3.2 mol Fe2O3 * 1 mol O2)/ 6 mol Fe2O3

x= 0.533 mol O2
