which formula represents an asymmetrical molecule
Answer:
Explanation:
An asymmetrical molecule is a molecule that has non-superimposable mirror images. In other words, the molecule cannot be superimposed on its own mirror image.
One way to represent an asymmetrical molecule is with the formula R-L, where R and L represent different groups attached to a central carbon atom. This formula indicates that the molecule has a chiral carbon, which is a carbon atom that is bonded to four different groups. Because the groups attached to the carbon atom are different, the molecule is asymmetrical.
Another way to represent an asymmetrical molecule is with the formula (R,R)-(S,S), where R and S represent different groups attached to a central carbon atom. This formula indicates that the molecule has two chiral carbons, each of which is bonded to two R groups and two S groups. Because the groups attached to the carbons are different, the molecule is asymmetrical.
Overall, the exact formula for an asymmetrical molecule will depend on the specific groups attached to the central carbon atom(s) and the arrangement of those groups.

what are phosphorus and nitrogen primarily used for? explain why these elements are so important (5 points).
suggest a reason for why the addition of bromine to fumaric acid requires a high temperature while the other substrates tested reacted at room temperature?
Rising in temperature accelerates the formation of fumaric acid while decreasing the final yield. Thus, the addition of bromine to fumaric acid requires high temperature.
In the presence of a relatively small amount of bromate, maleic acid in aqueous sulfuric acid isomerizes catalytically to fumaric acid in the dark at room temperature. The concomitant presence of a suitable amount of bromine in CCI, phase raises the rate and yield significantly. The yield and rate of isomerization depend on the relative amounts of maleic acid, bromate, bromine, and sulfuric acid. For a favorable condition, nearly 90% yield can be obtained.
The presence of cumene or benzene inhibits the isomerization. Hypobromous acid is proposed to play a major role in catalyzing the isomerization. A mechanism is proposed to rationalize the experimental results.

Rubidium-87 to strontium-87 radioactive decay has a half life of 4.88 1010 years. According to nuclear chemistry analysis, a particular rock sample has 0.423 mmol of strontium-87 for every 1.000 mmol of Rb-87.
Strontium-87 is produced when the naturally occurring isotope rubidium-87 decays by beta emission. The theory behind a technique for dating rocks is based on this deterioration. There are detectable levels of rubidium (Rb) and strontium (Sr) in the majority of igneous, metamorphic, and sedimentary rocks. However, because they are nearly never present in amounts greater than 1%, these elements are rarely found in normal chemical analyses. Strontium does create a carbonate (strontianite) and a sulfate (celestite), which are found in some hydrothermal deposits and certain sedimentary rocks, particularly carbonates, but neither rubidium nor strontium is a substantial component in the common rock-forming silicate minerals.

117 grams of liquid water are in a cylinder with a piston maintaining 1 atm (101325 Pa) of pressure. It is exactly at the boiling point of water, 373.15 K. We then add heat to boil the water, converting it all to vapor. The molecular weight of water is 18 g/mol and the latent heat of vaporization is 2260 J/g.
What is the parameters?Let's state the parameters given.
Given that:
mass (m) = 117 gram
specific latent heat of vaporization (L) = 2260 J/g
Pressure (P) = 1 atm or 101325 Pa
Temperature (T) = 373.15 K

i.e we are to find the heat energy which is denoted by Q = mL
Q = 117g × 2260 J/g
= 264420 J
= 264.42 KJ
and the water vapor takes up some final volume
If we assume that the vapor is an ideal gas.
We can represent the parameters using the equation of an ideal gas:
PV=nRT
where;
P = 1 atm or 101325 Pa
n = no of moles of the water
n = mass/molecular weight
= 117/18
= 6.5 mole
R = 8.314
T = 373.15
= 0.199 m³
At Constant Pressure, the work done by the vapour in pushing on the piston can be calculated as:
W =(ΔV)
= 101.325 × (0.199 - 0)
= 101.325 × 0.199
= 20.16KJ
Let ΔU = water internal energy change
Q = Heat Energy
W = work done by the vapour in pushing on the piston
Q = ΔU + W
ΔU = - Q + W (by multiplying the left hand side with minus (-))
ΔU = Q - W
ΔU = 264.42 - 20.16

if a small weather balloon with a volume of 42.0 l at a pressure of 1.00 atmosphere was deployed at the edge of typhoon odessa, what was the volume of the balloon when it reached the center?
The volume of the balloon at the center of the typhoon is 43.75L.
The low atmospheric pressure at the core of a tropical storm affects how powerful it is. Typhoon Odessa, which made landfall in the Pacific Ocean in August 1985, had winds that could reach 90 miles per hour and a pressure that was 40.0 mbar lower at the centre than the surrounding atmosphere. When Hurricane Andrew (shown), which had winds of up to 165 mph, struck south Florida, its central pressure was 90.0 mbar lower than its surroundings.
It is presumed that the temperature is constant because no variations were mentioned. Therefore, the new volume at the core of Typhoon Odessa is calculated using Boyle's law, which explains the relationship between pressure and volume. According to Boyle's law, P1V1 = P2V2 in mathematics.
If we assume that 1 bar = 1 atm, 1 mbar = 0.001 atm, and 40 mbar = 0.040 atm
P1=1.0 atm, V1=42.0 litres, P2=1 atm - 0.040 atm = 0.960 atm, and V2=?
Employing P1V1 = P2V2
V2 = P1V1/P2
V2 = 1.0 * 42.0 / 0.96
V2 = 43.75L

How does the difference between the ranges of the strong nuclear force and the coulomb force affect the makeup of each atom’s nucleus?
The difference between the ranges of the strong nuclear force and the coulomb force that holds atomic nuclei together is the nuclear force, the tight force between nucleons.
At very short distances, nuclear forces repel, keeping protons and neutrons from getting too close to each other. The strong force holds together quarks, the elementary particles that make up the protons and neutrons of the atomic nucleus, and further holds the protons and neutrons together into the atomic nucleus.
As such, it is responsible for the underlying stability of matter. The nuclear force arises from the exchange of virtual optical mesons, such as virtual pions, and two types of virtual mesons with spin (vector mesons), rho mesons and omega mesons.

Carbon 14 is an isotope of carbon, which has longest life amongst the three isotopes of carbon but very low abundance as compared to the other isotopes of carbon.
Carbon-14 nucleus has six protons and eight neutrons, for an atomic mass of 14.
It is a radioactive isotope of carbon.
Its half life is too high which makes it useful for dating in archaeology and to know age of fossils.
Carbon-14 decays slowly in a living organism. After the organism dies, it ceases to absorb carbon-14, such that the amount of the isotope in the tissues of decayed organisms decreases.
It has a half-life of 5,730 ± 30 years which means half of the amount of the isotope present at any instant will undergo disintegration during the next 5,730 years.
Carbon-14 decays at a constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its leftover carbon-14.

This very useful relationship is often used in the working with gases. At STP, all gases occupy 22.4 liters. It is a very useful conversion factor that is very useful in gas law calculations.
If Vanadium lost an electron how would it's electron configuration change? Why?
Answer:
Vanadium is a transition metal, so it can lose an electron from its outermost energy level to form a positively charged ion.
If Vanadium loses an electron, its electron configuration would change to reflect the loss of an electron.
For example, the electron configuration of Vanadium in its neutral state is [Ar] 3d^3 4s^2.
If it loses an electron, its electron configuration would change to [Ar] 3d^3.
This is because the lost electron would come from the 4s orbital, which is the outermost energy level of Vanadium.
