The question is incomplete, the complete question is shown in the image attached.

Answer:

1) No, it has the right number of valence electrons but does not satisfy the octet rule.

2) Yes

3) No, it has the wrong number of valence electrons, the correct number is 16

Explanation:

If we look at the first structure in the image(HCN), it easy to see from inspection that nitrogen has three valence electrons as it is normally supposed to have. However, if we count all the electrons around nitrogen, we will notice that they are six instead of eight. Thus nitrogen has not satisfied the octet rule here.

The structure HBr satisfies the octet rule, hence it is a reasonable Lewis structures for the compound shown.

CO2 has 16 valence electrons but the structure shown contains about 20 valence electrons hence it is not a reasonable Lewis structure for the compound.

Yes, in HCO⁺ the proposed lewis structure is reasonable.

No, COCl₂ has the wrong number of valence electrons.

No, OH⁻ has the right valence electron but does not obey the octet rule.

The correct structure for the question can be seen in the image attached below.

In the proposed structure, the number of valence electrons in HCO⁺ is: ( 1 + 4 + (6-1) ) = 10e⁻

Thus, the atoms obey the octet rule and the number of calculated valence electrons corresponds with what we have in the given structure.

Yes, the structure is correct and reasonable.

In COCl₂, the central carbon bonding to the oxygen is supposed to be doubly bonded and not singly bonded.the number of valence electron in COCl₂ is: ( 4 + 6 + (7 × 2)) = 24e⁻

The calculated number of valence electrons is different from the given structure of 26e⁻, so we can say No, it has a wrong number of valence electrons.

In the third structure, oxygen is supposed to have three lone pairs of electrons in order to obey the octet rule.the number of valence electrons in the structure is: (6 + (1+1) = 8e⁻

But both H, as well as, O do not obey the octet rule. Therefore, we say No, it has the right number of valence electron but do not obey the octet rule.

Explanation:

The number of yeast cells in a laboratory culture increases rapidly initially but levels off eventually. The population is modeled by the function а n = f(t) = 1 + be-0.90 where t is measured in hours. At time t = 0 the population is 30 cells and is increasing at a rate of 24 cells/hour. Find the values of a and b. a = b = According to this model, what happens to the yeast population in the long run? O The yeast population will shrink to 0 cells. The yeast population will stabilize at 270 cells. The yeast population will stabilize at 135 cells. The yeast population will stabilize at 8 cells. O The yeast population will grow without bound.

Answers

Answer:

Explanation:

[tex]n=f(t)= \frac{a}{(1+be^{-.9t})}[/tex]

At t = 0

30 =  [tex]\frac{a}{1 + b }[/tex]

30 + 30 b = a

 [tex]\frac{dn}{dt} =f(t)= \frac{-.9abe^{-.9t}}{(1+be^{-.9t})^2}[/tex]

For t = o

[tex]\frac{dn}{dt} =f(t)= \frac{.9ab}{(1+b)^2}[/tex]

given

24 = [tex]\frac{.9ab}{(1+b)^2}[/tex]

24 = [tex]\frac{30\times.9b }{1+b}[/tex]

24 = 27b / 1 + b

24 + 24 b = 27 b

24 = 3 b

b = 8

a = 30 + 30 x 8 = 270

[tex]n=f(t)= \frac{a}{(1+be^{-.9t})}[/tex]

Put t = infinity

n = a = 270

So at infinite time yeast population will stabilise at number 270 .

Zinc has an average atomic mass of 65.37 amu. Jack is trying to figure out what the most abundant isotope of zinc is, but he doesn't have access to the internet, so the average atomic mass is the only information he has. Jack decides to made an educated guess as to the most abundant isotope of zinc by assuming there are only two isotopes of zinc. If Jack assumes there are only two isotopes of Zn, what he be most likely to decide is zinc's most abundant isotope?
Question 5 options:

Zinc-68


Zinc-66

Answers

Zinc's most abundant isotope : Zinc-65

Further explanation

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

Mass atom X = mass isotope 1 . % + mass isotope 2.%

To decide zinc's most abundant isotope, then choose the closest mass number

or we can check the difference with the average mass number, if the value is the smallest, then that isotope has the largest abundant

Zinc-64

[tex]\tt \dfrac{65.37-64}{65.37}=0.021[/tex]

Zinc-65

[tex]\tt \dfrac{65.37-65}{65.37}=0.005[/tex]

Zinc-68

[tex]\tt \dfrac{68-65.37}{65.37}=0.04[/tex]

Zinc-66

The closest = Zinc-65(the smallest)

A student mixed several different 12 mm plastic beads together by mistake. Luckily the beads had different densities. One group of beads had a density of 0.6 g/cm3; the other beads had a density of 1.2 g/ cm3. Describe a method the student can use to sort the beads.

Answers

Answer:

The answer is "Each student will get a glass of water and drop the bead into it  but the beads float 0.6 g / cm3 and slip down to 1.2 g / cm3

".

Explanation:

One's masses would've been dissimilar, even though their width and concentrations were also equal. Whenever the type-A mass is m,  then the type-B mass is 2 m. One should measure then, therefore.  

Water has a 1g / cm^3 density. Although Type A is higher than air, Type B is much more compact. it means will float if they place  it in water type-A where type-B sinks.

can someone explain what radioisotopes are?

Answers

Answer:

A radioisotope is a radioactive isotope.

Explanation:

On the Periodic Table, elements 92 and up are radioactive. So that is Uranium and any higher elements. Remember that radioactive elements love to decay and are dangerous.

Isotopes are different forms of an element. For instance, we could have different amount of neutrons in the same element (same number of protons).

We could have an element like He - 4 vs. He - 6, where He - 4 would have 2 neutrons and He - 6 would have 4 neutrons.

So a radioisotope would be an elemental isotope that is radioactive. A good example of this is Uranium.

We have thousands of different isotopes of Uranium, but 2 are well known: Uranium - 235 and Uranium - 238. Both are the same element with the same amount of protons, but both have a different amount of neutrons.

Answers

Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains.

Ribosomes are cell structures that make protein. They are the primary site of the synthesis of protein. They are made up of protein and RNA.

What are ribosomes?

Ribosomes are cell organelles scattered in the cytoplasm of the cell. They are tiny and round vesicles. They are present in both prokaryotic and eukaryotic cells. Furthermore, they are present freely in the cytoplasm. Ribosomes are also present near the endoplasmic reticulum.

Ribosomes are made up of RNA and protein, and they synthesize the protein in the cell. Ribosomes read the mRNA and by these codes of mRNA, it constitutes amino acids, that grow into a long chain of the protein.

Thus, ribosomes are the parts of cells that produce protein. They serve as the central location for protein production. They are composed of RNA and protein.
