Agree with the statement buddy
Explanation:
A compound or molecule which will have least dissociation and that is not able to given hydrogen ion easily upon dissociation will also have a low value of 
.
Dissociation of the given compounds or species will be as follows.
As, chemical formula of bicarbonate is 
and due to the presence of a negative charge it is difficult to lose a positively charged hydrogen ion. This is because oppositely charged ions will be bonded by strong force of attraction.
Hence, it will not easily lose a hydrogen ion due to which bicarbonate has the lowest .
Thus, we can conclude that out of the given species bicarbonate has the lowest .
Answer:
No, he is not.
Explanation:
When he let the rubber band go, the band compresses, so there's elastic potential energy in it, which will be transformed into kinetic energy when it gains velocity and flies across the room.
Then, Elias had inverted the concepts: the experiment demonstrates the transformation of elastic potential energy to kinetic energy.
Answer:
Final pH of the solution = 5.46
Explanation:
The detailed step is shown in the attachment.
Answer:
5.5 moles of sodium are produced
Explanation:
Given data:
Number of moles of hydrogen = 2.75 mol
Number of moles of Na produced = ?
Solution:
Chemical equation:
H₂ + 2NaCl → 2HCl + 2Na
Now we will compare the moles of hydrogen and sodium from balance chemical equation:
H₂ : Na
1 : 2
2.75 : 2/1×2.75 = 5.5 mol
Thus, 5.5 moles of sodium are produced.
