If 16.00 g of O₂ reacts with 80.00 g NO, how many grams of NO₂ are produced? (enter only the value, round to whole number)
Norma-Jean [14]

Answer:

46 g

Explanation:

The balanced equation of the reaction between O and NO is

2 NO  +  O₂  ⇔  2 NO₂

Now, you need to find the limiting reagent.  Find the moles of each reactant and divide the moles by the coefficient in the equation.

NO:  (80 g)/(30.006 g/mol) = 2.666 mol

        (2.666 mol)/2 = 1.333

O₂:  (16 g)/(31.998 g/mol) = 0.500 mol

     (0.500 mol)/1 = 0.500 mol

Since O₂ is smaller, this is the limiting reagent.

The amount of NO₂ produced will depend on the limiting reagent.  You need to look at the equation to determine the ratio.  For every mole of O₂ reacted, 2 moles of NO₂ are produced.

To find grams of NO₂ produced, multiply moles of O₂ by the ratio of NO₂ to O₂.  Then, convert moles of NO₂ to find grams.

0.500 mol O₂ × (2 mol NO₂/1 mol O₂) = 1.000 mol NO₂

1.000 mol × 46.005 g/mol = 46.005 g

You will produce 46 g of NO₂.

What does the bottom number within each box of the periodic table refer to? How can it be used to determine the number of neutro
geniusboy [140]
The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element's atom. Every element has a unique atomic number.
