M1V1 = M2V2
37.5 mL * 0.245M = 18.0 mL * x M
(37.5*0.245)/18 = x M
x = 0.510
0.510 M is the answer.
Answer:
See explanation
Explanation:
In looking at molecules to determine whether they are polar or not we have to look at two things basically;
i) presence of polar bonds
ii) geometry of the molecule
Now, we know that CCI2F2 is a tetrahedral molecule, but the molecule is not symmetrical. It has four polar bonds that are not all the same hence the molecule is polar.
In an electric field, polar molecules orient themselves in such a way that the positive ends of the molecule are being attracted to the negative plate while the negative ends of the molecules are attracted to the positive plate.
So the positive ends of CCI2F2 are oriented towards the negative plate of the field while the negative ends of CCI2F2 are oriented towards the positive ends of the field.
5= Both parents must both be Heterozygous (Ee) because they have unattached earlobes but can still produce offsprings with attached earlobes because they still possess the recessive gene (e).
6=Punnett Square: (top right)-tt, (bottom right)-tt. Genotypes= Tt, Tt, tt, tt. Phenotypes= Roller(Tt), Roller(Tt), unable to roll(tt), unable to roll(tt).
<span>For 1 mole of MgCl2, it would require 2 moles of KOH. ( 1 : 2 mole ratio)
Since you have 3 moles of KOH, it is in excess, and MgCl2 is the limiting reactant.</span><span>

Answer:
If the Earth did not rotate on its axis, the atmosphere would only circulate between the poles and the equator in a simple back-and-forth pattern.
