Hello!
The approximate bond angle around the central carbon atom in acrolein is
120°
The structure of acrolein is shown in the figure below. From the structure, we can deduce that the central carbon atom is in an sp2 hybridization (Atoms with a double bond hybridize in an sp2 fashion).
Atoms with sp2 hybridization have trigonal planar geometry, in this kind of hybridization, bonds are oriented the farthest away possible from each other, to minimize overlapping and the angle that allows that is 120°.
Have a nice day!
Answer:
<h2>14.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.05 moles</h3>
Hope this helps you
Answer:
0.04 M
Explanation:
From the question given above, the following data were obtained:
Initial volume of solution (V1) = 25 cm³
Initial Molarity of solution (M1) = 0.4 M
Final volume of solution (V2) = 250 cm³
Final Molarity of solution (M2) =?
We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.4 × 25 = M2 × 250
10 = M2 × 250
Divide both side by 250
M2 = 10/250
M2 = 0.04 M
Therefore, the resulting molarity of the diluted solution is 0.04 M
