Answer:
C
Explanation:its right
The correct structure that corresponds to the name 2,2,3-trichloro-3-fluorohexane is both. Thus option C is correct.
What is chemical structure?Chemical structure is defined as the physical configuration of atoms within a molecule. The molecular geometry of the molecule is determined by its chemical structure. By illustrating how the atoms and chemical bonds are arranged in space within the molecule, chemical structure can be used to establish the molecular geometry of a product. Chemists can now see a crucial visual depiction of a chemical formula thanks to this.
2,2,3-trichloro-3-fluorohexane structure given is both are correct as one of the structure is trans form and the other is cis form of the structure. Option A is trans form while option B is cis form of structure.
Thus, the correct structure that corresponds to the name 2,2,3-trichloro-3-fluorohexane is both. Thus option C is correct.

what volume of a 0.25M solution can be prepared with 28.5g of k2s? (molar mass=110.26g)
Answer:
volume = 1.04 dm^3
Explanation:
Data:
volume = ?
Molarity, M = 0.25M
mass = 28.5g
Molar mass = 110.25g
Moles = ?
Solution:
First find number of moles,
moles = mass in gram / molar mass
= 28.5 / 110.25
= 0.258
≈ 0.26 moles
Now,
Molarity = [tex]\frac{no. of moles}{volume in dm^3}[/tex]
So,
Volume in dm^3 = [tex]\frac{no. of moles}{molarity}[/tex]
= 0.26 / 0.25
Volume = 1.04 dm^3
Which of the following quantities represents the greatest volume?
A) 300 microliters
B) 3.0x106 nanoliters
C) 3.0x104 deciliters
D) 3.0x10-12 kiloliters
E) 3.0 milliliters
The lowest and largest conversion factors are nanoliters and kiloliters, respectively. Among all the given options, the correct option is option C.
What is volume?A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Although there are many different units that may be used to indicate volume, the most common ones are liters, m³, gallons, milliliters, teaspoons, as well as ounces.
Gases have a volume equal to the internal capacity of the container since they fill their containers to the brim. Containers with a designated volume or one whose interior form is known are frequently used to measure liquids. Measuring cups, graded cylinders, flasks, as well as beakers are a few examples of the tools used to quantify liquid volume. 3.0x10⁻¹²kiloliters represents the greatest volume.
Therefore, the correct option is option C.

What is the mass of carbon monoxide (CO) gas if the gas occupies a volume of 4.1 L at 2.0 atm of pressure and -73oC?
Answer:
1.7
Explanation:
A truck tire at 82.0L at 32.5°C and 1.9 atm has a temperature change to-15.4°C and a pressure change to 770.0 mmHg. Calculate how much the volume of the
air in the tire will change.
Answer:
+ 47.68 Liter change in volume to final volume 129.68 L
Explanation:
P1V1/T1 = P2V2/T2 RE-ARRANGE TO:
P1V1/T1 * T2/P2 = V2 (T must be in Kelvin)
1.9 * 82 / (273.15 + 32.5) * (273.15-15.4)/ (770/760) = 129.68 L
129.68 - 82=47.68 L change

Answer:
1.The electonic configuration of elements and their position in the periodic table are related to each other, From the electronic configuration of the elements, we can determine the period and the group to which the element belongs
Let's consider, sodium with atomic number 11 and k, l, and M shells have 2,8,and 1 electrons. since, there are 3 principal energy levels so we concluded sodium belongs to third period M Shell(valance shell) has only 1 electrons. so sodium belongs to group 1.
2. Entire D-block elements are known as Transition Elements.
