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.
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.
Answer:
How we can use images to promote and communicate science ... the cliché, “a picture tells a thousand words”, but there is real value in ... Images help us learn, images grab attention, images explain tough ... at BioMed Central, one thing I've realised is how vital images are in my role. ... Here's an example:.
Explanation:
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%
Answer:
Ca3P2
Explanation: find out what 66% of the molar weight of the molecule is and then find out how many moles of Ca that would be by dividing it by the molar weight of Ca
then do the same for P
