Answer:
Polarity
Explanation:
Covalent bonds may be either polar or nonpolar. Polar molecules, such as water, are asymmetric molecules that have unbalanced electronegativity, leading to slight charges on the atoms within the molecule.
Water's polarity
The chemical equation for water is [tex]H_20[/tex]. In this molecule, oxygen has 2 unbonded electron pairs. This causes the molecule to have a bent geometry. Bent molecules are always polar due to the dipoles formed by the unshared electron pairs. These dipoles create a slight negative charge on the oxygen atom and a slight positive on the hydrogen atoms.
Intermolecular Forces
Due to the slight charges of a water molecule, the oxygen molecules attract positive ions, and the hydrogen atmos attract negative ions. This interaction is known as an ion-dipole intermolecular force (IMF).
Answer:
Polarity
Explanation:
Polarity in a substance or molecules arises when the two combining atoms have different electronegativities. As more electronegative atoms will attract the electrons from electropositive atoms toward itself.
Due to this, there will be development of partial positive charge on electropositive atoms and a partial negative charge on the electronegative atoms.
For example, in water (H₂O) due to the difference in electronegativities of the hydrogen and oxygen atoms, there is a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Due to these charges it is able to attract ions of opposite charges that are surrounding.
Thus, we can conclude that one of the most important characteristics of the water molecule is it's polarity, which allows it to surround and attract both positive and negative ions.

Nucleophilicity is a kinetic property. A higher nucleophilicity indicates that the nucleophile will easily donate its electrons to the electrophile and that the reaction will occur at the faster rate. The reaction rate also depends on the nature of the electrophile and solvent. Rank the following reactions from fastest to slowest based on the nucleophilicity of the nucleophile
From the fastest to the slowest based on the nucleophilicity of the nucleophiles, the order is represented as:
[tex]\mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^- \ }\\ \\ \\ \mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^- \ } \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^- \ }[/tex]
What are Nucleophilic functional groups?Nucleophilic functional groups include electron-rich atoms capable of donating an electron pair in order to establish a new chemical covalent bond. The most frequent nucleophilic functional groups are:
Water, Alcohols, Phenols, Amines, Thiols, etcThe protonation state of these functional groups has an effect on their nucleophilicity. Also, the trend of nucleophilicity goes from:
Tertiary,Secondary, PrimaryThe following reactions that we are supposed to find their order is given as follows:
[tex]\mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^-} \\ \\ \\ \mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^-} \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^-}[/tex]
From the fastest trend of the nucleophilicity of the nucleophile to the slowest, the correct arrangement is as follows:
[tex]\mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^- \ \ \ ---(2'' \ ^0) \ \\}\\ \\ \\ \mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^- \ \ \ \ ---(1^0) } \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^- \ \ \ --- \ \ \ \ (1^0)}[/tex]
The first reaction has two functional groups of methyl (-CH_3) attached to it which increases its nucleophilicity to the second one which has one methyl functional group attached to it.

Note that the probability that Micah is included in the group of students chosen is approximately 0.000305, or about 0.03%.
How to compute the above probabilityMicah's probability of being included in the group of students chosen can be calculated using combinations. There are a total of 28 students in the class, and the teacher is selecting 3 students.
The probability of Micah being chosen can be calculated as:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Number of favorable outcomes = 1 (Micah being selected)
Total number of possible outcomes = Number of ways to choose 3 students out of 28 = C(28, 3) = 3276
Probability = 1 / 3276
≈ 0.000305

You get a $60,000 loan for a new dump truck. With the truck, you can generate $500 more business each week at 80% margin. Your interest rate on the loan is 8. 6%. Does the additional margin generated cover the interest payments?
Assuming your interest rate on the loan is 8. 6%. The additional margin generated will cover the interest payments.
Additional margin
Let determine the weekly interest
Weekly interest= 8.6% /12 x 60,000
Weekly interest= $99.23
Let calculate the amount left since the business generates $500 at a margin of 80
Amount left= 500 x 80%
Amount left= $400

In peas, purple flowers are dominant over white flowers. If two heterozygotes are crossed, what fraction of the population will have white flowers?
The fraction of the population will have white flowers after the crossing of the heterozygotes is; 1/2
What is the result of the heterozygote crossing?P = purple gene
p = white gene
Punnet squares shows the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white which translates to the fact that there is a 50% chance of having either genotype, of being purple or white.
