Answer:

The volume of 50% alcohol used to make the mixture = 31.25 L

The volume of 10% alcohol used to make the mixture = 18.75 L

Explanation:

Let the volume of 50% alcohol used to make the mixture = x L

Let the volume of 10% alcohol used to make the mixture = y L

Total volume of the mixture = x + y = 50 L .................. (1)

For 50% alcohol:

C₁ = 50% , V₁ = x L

For 10% alcohol :

C₂ = 10% , V₂ = y L

For the resultant alcohol solution:

C₃ = 35% , V₃ = 50 L

Using  

C₁V₁ + C₂V₂ = C₃V₃

50×x + 10×y = 35×50

So,  

5x + y = 175 .................. (2)

Solving 1 and 2 we get,

<u>x = 31.25 L </u>

<u>y = 18.75 L</u>

What is the approximate bond angle around the central carbon atom in acrolein?
Soloha48 [4]

Answer:

The approximate bond angle around the central carbon atom in acrolein is 120°.

Explanation:

The structure of acrolein is shown in the attachment. 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°.
