Answer:1.309 x 10^24 oxygen atoms

Explanation:

Molar mass of N2O4,=  2 x Molar mass of Nitrogen + 4 x Molar mass of Oxygen

= 2 x 14.01 + 4 x 16.0

= 92.02 g/mol

One mole of a substance is equal to 6.022 × 10²³ unit/ atoms/ molecules

In N2O4, there are 4  moles of Oxygen

if 92.02 g contains = 4 x 6.022 x 10 ^23 molecules

50.0 g wll contain=  (4 x 6.022 x 10 ^23  x 50)/ 92.02g

1.309 x 10^24 oxygen atoms

Ammonia and oxygen react to form nitrogen monoxide and water. Construct your own balanced equation to determine the amount of NO
stiv31 [10]

Answer:

NO would form 65.7 g.

H₂O would form 59.13 g.

Explanation:

Given data:

Moles of NH₃ = 2.19

Moles of O₂ = 4.93

Mass of NO produced = ?

Mass of  produced H₂O = ?

Solution:

First of all we will write the balance chemical equation,

4NH₃ + 5O₂   →   4NO + 6H₂O

Now we will compare the moles of NO and H₂O with ammonia from balanced chemical equation:

NH₃  :   NO                                   NH₃  :   H₂O

4     :    4                                          4    :      6

2.19   :    2.19                                 2.19  : 6/4 × 2.19 = 3.285 mol

Now we will compare the moles of NO and H₂O with oxygen from balanced chemical equation:

O₂  :   NO                                               O₂ :   H₂O

5     :    4                                                  5     :    6

4.93   :   4/5×4.93 = 3.944 mol               4.93  : 6/5 × 4.93 = 5.916 mol

we can see that moles of water and nitrogen monoxide produced from the ammonia are less, so ammonia will be limiting reactant and will limit the product yield.

Mass of water = number of  moles × molar mass

Mass of water = 3.285 mol × 18 g/mol

Mass of water = 59.13 g

Mass of nitrogen monoxide  = number of  moles × molar mass

Mass of nitrogen monoxide = 2.19 mol × 30 g/mol

Mass of nitrogen monoxide = 65.7 g

How many moles of SO2 are required to produce 0.45 mole CS2?
Kaylis [27]

Answer: The moles of carbon needed will be, 13.8 moles

Explanation: Moles of  = 5.52 mole

Now we have to calculate to moles of carbon.

The given balanced chemical reaction is,

From the balanced chemical reaction, we conclude that

As, 2 mole of  react to give 5 moles of carbon

So, 5.52 mole of  react to give  moles of carbon

Therefore, the moles of carbon needed will be, 13.8 moles
