On the basis of oxidation number consideration which of the following does not react with molecular oxygen no ,n2o,so2,so3,p4o6
sesenic [268]
N oxidation number in N₂O = 1
S oxidation number in SO₂ = 4
S oxidation number in SO₃ = 6
P oxidation number in P₄O₆ = 3
Therefore, the Sulfur in SO₃ will not react with molecular oxygen as Sulfur is already using all of its valence electrons in bonding.

Based on its location on the period table what can most likely be predicted of phosphorus
Natalka [10]
Hi, I believe this question is asking what charge Phosphorus will have when it forms an ion. If that is the case, you will see that it based on the column it is in, neutral Phosphorus has 5 valence electrons. When it becomes an ion (has 8 valence electrons), it will GAIN three electrons. Meaning, we can predict that Phosphorus will have a 3- charge when it becomes an ion.

21 pts. Sodium reacts with oxygen to produce sodium oxide as described by the balanced equation below. If 54.1g of sodium reacts
Aleksandr [31]
First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and  the balanced chemical reaction,

   theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)
       
      theoretical amount of Na2O = 72.9 g of Na2O


Calculation of percent yield,

                % yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
                 % yield = 84.75%

Answer: 84.75%
