Answer:
None of carbonyl group is attached to hydrogen atoms.
Explanation:
Ketone is a group in which one carbonyl group is attached to two R ( the alkyl group) .
And the group in which two hydrogen is attached to R is called as aldehyde (formaldehyde).
And when one hydrogen and one alkyl group is attached to R. It is called as acetaldehyde from aldehyde family.

The freezing point depression of water is 1.86°C/m.kg
<span>K2S dissociates: </span>
<span>K2S ↔ 2K+ + S 2- </span>
<span>1mol K2S will produce 3 mol of ions. </span>
<span>Therefore in the freezing point equation: i = 3 </span>
<span>Depression of freezing point = Kf * i* m </span>
<span>Depression of freezing point = 1.86*3*0.195 </span>
<span>Depression of freezing point = 1.088°C </span>
<span>The solution will freeze at - 1.088°C </span>
From the ones that you are showing me <span>the more positive the potential the more likely: </span>
<span>Fe+3 + e- ---> Fe+2
I hope this is something very useful</span>
Any buffer exists in this equilibrium
HA <=>
In a buffer, there is a large reservoir of both the undissociated acid (HA) and its conjugate base (
)
When a strong acid is added, it reacts with the large reservoir of the conjugate base (
) forming a salt and water. Since this large reservoir of the conjugate base is used, the ph does not alter drastically, but instead resist the pH change.
Answer:
2.68 cm^3
Explanation:
Density= Mass/Volume
so...
8.96 g/cm^3 = 24.01 g/ V
and then u solve so it would be 2.68 cm ^3
