Answer:
50 formula units of NBr3 will yield 75 formula units of NaBr
57 formula units of NaOH will yield 57 formula units of NaBr
Explanation:
The equation of the reaction is ;
2NBr3 + 3NaOH – N2 + 3NaBr + 3HBrO
Number of formula units of NaBr formed when 50NBr3 reacts was obtained from;
2 formula units of NBr3 yields 3 formula units of NaBr
50 formula units of NBr3 will yield 50 ×3/2 = 75 formula units of NaBr
Hence 50 formula units of NBr3 will yield 75 formula units of NaBr
Then;
Since 3 formula units of NaOH yields 3 formula units of NaBr
57 formula units of NaOH will yied 57×3/3 = 57 formula units of NaBr
Hence 57 formula units of NaOH will yield 57 formula units of NaBr
Answer:
Explanation:
Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.
Answer:
4
Step-by-step explanation:
The reactions are:
Glycolysis: 1 glucose ⟶ 2 pyruvate
Link reaction: 2 × [1 pyruvate ⟶ 1 acetyl CoA]
Citric acid cycle: 2 × [1 AcetylCoA ⟶ 2 CO₂]
Now, add the reactions, cancelling species that occur on both sides of the reaction arrow,
1 glucose ⟶ <u>2 pyruvate
</u>
<u>2 pyruvate</u> ⟶ <u>2 acetyl CoA
</u>
<u>2 AcetylCoA </u>⟶ 4 CO₂
<em>Overall</em> : 1 glucose ⟶ 4 CO₂
For each mole of glucose, four molecules of CO₂ are released in the citric acid cycle.
A table would show the exact values at certain times, while some kinds of graphs only show approximate values but for the “slight changes” it is best to have the exact numbers.
