The carbon = carbon double bonds in unsaturated fatty acids are restricting the movement of the molecule branches. They are more "kinked" up and do not pack as tightly. whereas, saturated fatty acids have more freedom of movement and tend to pack together better. Therefore, in the case of unsaturated fatty acids they can not compact tightly together and there are less van der Waals interactions between the molecules, and so the melting point is reduced.
Answer:
B. Velocity
Explanation:
The answer is Velocity because the def of velocity is the rate of constant speed in a given direction. I hope this helps, have a good night.
<span>Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.</span>
250.00 mL) x (1.0 M ) / (2.5 M) = 100 mL
So take 100 mL of 2.5 M HCl and dilute it to 250 mL.
