Answer: 3.6%
5.5 - 5.3 and divide it by 5.5. Then multiply this by 100
Explanation:
This will get you 3.6%
Answer : The mass of needed are, 44.5 grams.
Explanation :
First we have to calculate the moles of Na.
Now we have to calculate the moles of NaCl.
The balanced chemical reaction is:
From the reaction, we conclude that
As, 2 mole of produces from 2 mole of
So, 0.761 mole of produces from 0.761 mole of
Now we have to calculate the mass of
Molar mass of = 58.5 g/mole
Therefore, the mass of needed are, 44.5 grams.
Answer:
F
Explanation:
Halogens may interact with the benzene ring via inductive or resonance effects. Halogens deactivate the benzene ring by inductive effect rather than by resonance effects.
The lone pairs of electrons present on the halogen atoms may be donated to the ring by resonance, but an opposite effect, the inductive pull (-I inductive effect) of the halogen atoms on electrons away from the benzene ring due to the high electro negativity of the halogens leads to a deactivation of the ring towards electrophilic substitution.
Hence inductive electron withdrawal by the halogen atom predominates over electron donation by resonance effect and the benzene ring g is deactivated towards electrophilic substitution at the ortho and para positions.
Answer : The partial pressure of is, 88.84 atm
Solution :
The given equilibrium reaction is,
= 36.9 atm
= 16.8 atm
The expression of will be,
Now put all the values in this expression, we get
Therefore, the partial pressure of is, 88.84 atm
