Answer: amount of substance n = cV = 2.0 mol/l x 0.25 l = 0.50 mol
Explanation:
Answer:
B. NO
Explanation:
In each mole of NO, the weight of the oxygen is 16.00 g; the weight of the nitrogen is 14.01 g. Then in 80 g of NO, we have 42.65 g of oxygen and 37.35 g of nitrogen.
__
In each mole of NO₂, the weight of the oxygen is 2(16.00) = 32 g. The weight of the nitrogen is 1(14.01) = 14.01 g.
From the available oxygen, we can produce ...
(42.65 g +16 g)/(32.00 g/mol) = 1.83 mol of NO₂
From the available nitrogen, we can produce ...
(37.35 g)/(14.01 g/mol) = 2.67 mol of NO₂
Clearly, the reaction is limited by the amount of available oxygen.
NO is the excess reactant.
