Answer:
Step-by-step explanation:
CH3Cl is polar while CCl4 is non polar.
When we consider whether something is polar or not we have to consider the following:
-Molecular symmetry
-Polar bonds (based on Electronegativity)
-Whether or not all the bonds are equal in magnitude
So for CCl4:
-All of the bonds are equal, in that all the electronegativity differences (delta EN) are the same.
-There are polar bonds as the delta EN between Cl (EN = 3.0) and C (EN=2.5) is 0.5 which means the bond is polar covalent
But when we look at the symmetry of the molecule (by drawing the lewis structure) there are no lone pairs, meaning that the molecule is symmetrical and therefore, it is non polar.
For CH3Cl:
-There are polar bonds here whether between C-H or C-Cl like above, both delta EN are greater than or equal to 0.5
-But, all of the bonds are not equal in strength. Cl (3.0) atoms have much higher electronegativity values than H (2.1) and there for they will "pull" the electrons closer and polarize the molecule. Therefore, the differences in bonds causes this molecule to be asymmetrical, and hence polar.
Answer:
Negative number
Step-by-step explanation:
For example, |-5| = 55. This is because -5 is considered to be 5 units away from 0.

Answer:
Solve for f.
f(−4)=−3x+6
Step 1: Divide both sides by -4.
−4f/-4 = −3x+6/−4
f=3/4x + −3/2
Answer:
f= 3/4x + −3/2
So this problem would be written as this(:
so you start with 331 students together, but then you lose 7 who travel in the cars.
331-7=324
then it would be 324 divided by the 6 buses. that would look like this
324/6
that equals 54.
so in conclusion the answer is 54 students went into each bus:) hope that helps you!
Step-by-step explanation: To simplify, we will apply the <em>Quotient Rule</em>.
The 5's in this problem are bases so as you apply the quotient rule,
subtract the exponents but leave the base alone to get 5⁴.
We can also write 5⁴ as 5 · 5 · 5 · 5.
