The answer is A.<span>Boron and carbon are likely together in one period because they have very close atomic numbers, while gallium and germanium are likely together in another period because they have very close atomic numbers.

The element that  are most likely in the same period of periodic table is

<em> Boron  and carbon  are likely together in one period  because they  have  very close  atomic   number, while  gallium and germanium  are likely  together  in another period  because  they  have  very  close atomic  numbers ( answer A)</em>


<u>Explanation</u>

  • Element  in   same period  have the  close atomic  number .
  • The   atomic number of  an element is determined by number of protons the element have.
  • The number of proton are equal to number of electrons

Therefore   boron is in atomic number  5  with  2.3  electronic  configuration  while  carbon  is in atomic number 6 with 2.4  electron  configuration

since both  boron  and carbon  have two  energy level  they are in period 2.


Gallium  is in atomic number 31 with  2.8.8.8.5  electron configuration while Germanium (Ge)  is in atomic number 32 with  2.8.8.8.6  electron configuration.

Since  both gallium  and germanium  has 5  energy level they are in  same period (period 5)


  • for example  Aluminum,boron  and gallium are in group (iii)  since they have  3 valence electrons.

Reagent needed to convert sulphur dioxide to Sulphur
Harman [31]
<span>6 + x = 12. To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.</span>

Write the structure of the following compound:<br>=&gt; 3-(4-chlorophenyl)-2-methylpropane
Rudiy27

Answer:

See explanation and image attached

Explanation:

The IUPAC system of nomenclature enables the structure of molecules to be written seamlessly from the name of the compound. Hence it is commonly called the systematic nomenclature.

The parent chain here is propane. It is substituted at the 2- position by a methyl group and at the 3-position by 4-chlorophenyl group as we can see in the image attached to this answer.

If you obtain 3.0 grams of aspirin from an experiment that could make no more than 3.14 grams, what is the percent yield?
Masteriza [31]

Answer:

96%

Explanation:

To find the percent yield, we can use this equation

\frac{Actual}{Theoretical} *100

The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.

\frac{3.0}{3.14} *100\\\\ =96

Thus the percent yield is 96%

;)
