Answer:
N₂O₄ + 14 kcal ⇄ 2NO₂.
Explanation:
Since the sign of ΔH determines either the reaction is exothermic or endothermic:
+ve, the reaction is endothermic.
-ve, the reaction is exothermic.
∵ The change of enthalpy of this reaction when proceeding left to right is + 14 kcal (+ ve sign).
∴ The reaction is endothermic, the heat is a part of the reacatnts in the reaction.
So, the reaction is:
N₂O₄ + 14 kcal ⇄ 2NO₂.
Answer:
12 L of O₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
CS₂ + 3O₂ —> CO₂ + 2SO₂
From the balanced equation above,
3 L of O₂ reacted to produce 1 L of CO₂.
Finally, we shall determine the volume of O₂ required to produce 4 L of CO₂. This can be obtained as follow:
From the balanced equation above,
3 L of O₂ reacted to produce 1 L of CO₂.
Therefore, xL of O₂ will react to produce 4 L of CO₂ i.e
xL of O₂ = 3 × 4
xL of O₂ = 12 L
Thus, 12 L of O₂ is needed for the reaction.
Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number = 
Therefore, moles of 
hydrolyzed is as follows.
Moles of hydrolyzed = 
= 
= 0.00682 moles
Now, moles of hydolyzed per second is calculated as follows.
Moles of hydolyzed per second = 
= 
And,
Moles of enzyme = 
= 
= 
moles
Therefore, the value of 
is as follows.
= 
per second
= 
per minute
= 
per minute
Thus, we can conclude that the turnover number () of carbonic anhydrase (in units of 
) is per minute.
They resulted tasting unpleasant due to the opened bag and the oxegen that wasn't pass through.
So, you could put filters with holes based on the size of the average gram. Which means sugar grams or salt can fit through.
