Answer:
D
Explanation:
The graph of Boyle's law is known as pressure-volume graph or PV curve. It is as follows:
As observed from the graph above, pressure increases with a decrease in volume, and vice versa. Thus, pressure is inversely proportional to volume. Other parameters (temperature and amount of gas) are constant in the graph above.
Volume is on the x-axis and pressure, on the y-axis. The equation of the curve is PV = k, which is the equation of Boyle's law. The curve is hyperbolic in nature having two asymptotes: P = 0 (horizontal) and V = 0 (vertical).
As volume tends to positive infinity, pressure tends to zero, and we get the horizontal asymptote, P = 0.
Horizontal asymptote, P=0
When volume approaches zero, pressure approaches infinity, and it results in the vertical asymptote, V = 0.
The graph which shows the pressure-volume relationship expected for an ideal gas is: C) Graph D.
Boyle's states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyle's law is given by the formula:
[tex]PV = k[/tex]
Where;
P is the pressure of an ideal gas.V is the volume of an ideal gas.For the illustration of Boyle's law using a graph, volume is represented on the x-axis while pressure is represented on the y-axis.
Generally, the graph of Boyle's law is a hyperbolic curve with two asymptotes:
P = 0 (horizontal axis).V = 0 (vertical axis).Find more information: https://brainly.com/question/1437490

What do you have to do to break a molecule?
Answers
Answer:
Heat the molecule
Explanation:
Since most bonds require energy to form, they also give off energy when they are broken. But before most bonds break, the molecule has to be heated. Then the atoms start to move, and when they move too much, the bond breaks. Molecules that require less energy to break than they give off when broken are called fuels.
Which isomer of 1-bromo-2-tert-butylcyclohexane reacts faster when refluxed with potassium tert-butoxide?Draw the structure of the expected major product from the faster reacting compound.
Answers
Answer:
See explanation and image attached
Explanation:
The reaction of 1-bromo-2-tert-butylcyclohexane with potassium tert-butoxide is an elimination reaction that occurs by E2 mechanism.
The E2 reaction proceeds faster when the hydrogens are in an antiperiplanar position at an angle of 180 degrees.
This is only attainable in the trans isomer of 1-bromo-2-tert-butylcyclohexane. Hence trans 1-bromo-2-tert-butylcyclohexane reacts faster with potassium tert-butoxide

Answers
Answer:
The reaction that takes place in a nuclear fission reactor is answer D.
Explanation:
Step-by-step explanation:
Nuclear fission reactions involves the process by which large atomic nuclei are bombarded with energetic particles and release of an enormous amount of nuclear energy, which mainly ends up as heat energy.
So now, consider the nuclear reaction from D, after the uranium nucleus absorbs the neutron its split into two smaller nuclei (often radioactive themselves), Krypton and Barium and releases more neutrons (or energy).

Explanation:
Two isotopes of hypothetical element X exist with abundances of 30.00% 100X and 70.00% 101X. What is the approximate atomic mass of X (in atomic units, amu)?
(A) 100.3
(B) 100.5
(C) 100.7
(D) 101.0
Answers
Answer:
C. 100.7 amu
Explanation:
Isotopes of an element are atoms of an element with the same atomic number but different atomic masses. Each atomic mass of an isotope is known as an isotopic mass. An element that exhibits isotope, that is, that have two or more isotopes has a relative atomic mass that is not a whole number.
Relative atomic mass of X is the sum of the products of the relative abundances of each isotope and its isotopic mass.
For Isotope ¹⁰⁰X: 30% × 100 = 30 amu
For Isotope ¹⁰¹X: 70% × 101 = 70.7 amu
Relative atomic mass of X = (30 + 70.7) amu = 100.7 amu
Therefore, the approximate atomic mass of X is 100.7 amu
Taking into account the definition of mass number, isotopes and atomic mass of an element, the average mass of hypothetical element X is 100.7.
First of all, all atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them. Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged (electrons).
On the other hand, the mass number tells us the total number of particles in the nucleus. That is, the mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus.
The same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element.
Finally, the atomic mass of an element is the weighted average mass of its natural isotopes.
In other words, the atomic masses of chemical elements are usually calculated as the weighted average of the masses of the different isotopes of each element, taking into account the relative abundance of each of them.
In this case, two isotopes of hypothetical element X exist with abundances of 30.00% 100-X (the atomic mass is 100) and 70.00% 101-X (the atomic mass is 101). Then, the average mass of X can be calculated as:
100×0.30 + 101×0.70= 100.7
Finally, the average mass of hypothetical element X is 100.7.

Answer: MM = 16.55 g/mol
Explanation: Freezing point depression is a phenomena that explains why adding a solute to a solvent decreases the solvent freezing point: when a substance begins to freeze, its molecules slows down and rearrange itself forming a solid. If a solute is added, the molecules from the solvent interfere in the formation of the solid. To guarantee the transformation, the solution has to cooled down even more.
Freezing point and molality concentration is related by
[tex]\Delta T=T_{f}_{(solvent)}-T_{f}_{(solution)}=K_{f}.m[/tex]
where
ΔT is freezing point depression
[tex]T_{f}_{(solvent)}[/tex] and [tex]T_{f}_{(solution)}[/tex] are freezing point of solvent and solution, respectively
[tex]K_{f}[/tex] is freezing point depression constant
m is molality concentration
Dibenzyl ether is the solvent and has the following properties: [tex]K_{f}=[/tex] 6.27 and [tex]T_{f}[/tex] = 3.6°C.
Molality concentration is
[tex]m=\frac{T_{(solvent)}-T_{(solution)}}{K_{f}}[/tex]
[tex]m=\frac{3.6-1}{6.27}[/tex]
m = 0.415
Molality concentration is moles (n) of solute dissolved in a mass, in kilogram, of solvent.
[tex]m=\frac{moles}{mass(kg)}[/tex]
n = m(mass of solvent in kg)
n = 0.415(0.035)
n = 0.0145
Molar mass (M) is the weight of one sample mole and can be calculated as
[tex]n=\frac{m}{M}[/tex]
M = [tex]\frac{m}{n}[/tex]
m in grams
Molar mass of compound X is
[tex]M=\frac{0.24}{0.0145}[/tex]
M = 16.55
Molar mass of molecular compound X is 16.55g/mol
A system performed 145 kJ of work on the surroundings and absorbed 105 kJ of heat from the surroundings. What is the change in energy of the system?
Answers
Answer:
250 kJ
Explanation:
Step 1: Given data
Work performed by the system (w): 145 kJ (By convention, when the system performs work on the surroundings, w > 0)Heat absorbed by the system (q): 105 kJ (By convention, when the system absorbs heat from the surroundings, q > 0)Step 2: Calculate the change in the internal energy of the system
The internal energy of a thermodynamic system is the energy contained within it. We can calculate the change in the internal energy (ΔE°) using the following expression.
ΔE° = q + w
ΔE° = 105 kJ + 145 kJ = 250 kJ
