A) –7.8944×10-13 J/atom
Explanation:
Mass defect of a radionuclide (m)
[tex]=-8.7839[/tex]×[tex]10^{-30} kg[/tex]
Formula for binding energy
[tex]E=mc^{2}[/tex]
[tex]=(-8.7839x10^{-30} kg)(3x10^{8} m/s)^{2}[/tex]
[tex]E=-7.8944x10^{-13} J/atom[/tex]
If the mass defect for a radionuclide is – 8.7839 × 10⁻³° kg, the binding energy per atom will be –7.8944 × 10⁻¹³ J/atom. The correct option is A.
What is radionuclide?A radionuclide is an unstable nuclide because it contains so much charge. The excess energy is used by the gamma radiation by the nucleus, the electron uses energy to move to another orbital.
Radionuclides are particles that are used to scanning or monitor the radioactive chemicals that are in the body due to swallowing or inhaling.
The binding energy per atom can be calculated by the formula
The mass of defect of a radionuclide (m) is – 8.7839 × 10⁻³° kg
E = mc²
E = – 8.7839 × 10⁻³° x 3 x 10⁸ m/s
E = –7.8944 × 10⁻¹³ J/atom.
Thus, the correct option is A. –7.8944×10-13 J/atom.

Explain why people tend to wear light- colored clothing during the warmer months of the year. Use evidence and scientific reasoning to support your answer
Answer:
because dark colours like black attract light (sun) and heat. light colors reflect more light, (it absorbs less energy and heat from the sun)
Answer:
Because Black color absorbs light better than light-colored.
for example have you ever seen the black car on the road if you touch it very hotter than white car
1. White is the most reflective color. Does not absorb heat like black Make the house not hot.
2. White has the least radiation exposure. Therefore, during the winter night, it will help retain heat for a while. 3. Because white absorbs light as little as possible. Causing the pigment to deteriorate slowly Unlike black that absorbs light well. Causing the color to deteriorate and fade quickly until noticeable
4. If the house next to you is painted white during the day, it will help reflect light into the house.
Why that black color absorbs heat? Even though it abosrbs the light? It comes from the principle that (Substance or material) Black is what absorbs (absorbs) light in every technology.
It absorbs all widths of light, including infrared light. (The infrared itself is hot.)
Black repels self-heating the most because of all colors of light. But there is justice.

Explanation:
Reza has a glass ball filled with water that contains tiny plants and shrimp that eat those plants. No material can get in or out, but light can get through the glass when it is placed in sunlight.
The number of energy storage molecules in the plants and shrimp started out high, but then the glass ball was moved, and the number of energy storage molecules decreased. Was the glass ball moved into the light or into the dark? What happened to the amount of carbon in the water?
The glass ball was moved into the dark and the amount of carbon increased in water as there is no photosynthesis taking place.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

A mixture of He, Ar, and Xe has a total pressure of 2.40 atm. The partial pressure of He is 0.300 atm, and the partial pressure of Ar is 0.250 atm. What is the partial pressure of Xe?
Express your answer to three significant figures and include the appropriate units.
The partial pressure of Xe in the mixture is 1.850 atm. (partial pressure of Xe = Total pressure - Partial pressure of He - Partial pressure of Ar = 1.850 atm).
To find the partial pressure of Xe, we need to subtract the partial pressures of He and Ar from the total pressure.
Total pressure = partial pressure of He + partial pressure of Ar + partial pressure of Xe
Given:
Total pressure = 2.40 atm
Partial pressure of He = 0.300 atm
Partial pressure of Ar = 0.250 atm
Let's solve for the partial pressure of Xe:
Partial pressure of Xe = Total pressure - Partial pressure of He - Partial pressure of Ar
Partial pressure of Xe = 2.40 atm - 0.300 atm - 0.250 atm
Partial pressure of Xe = 1.850 atm
Therefore, the partial pressure of Xe in the mixture is 1.850 atm.

Write the overall balanced equation for the reaction:
N2O4(g) + CO → NO(g) + CO2(g)+NO2(g)
Answer:
This reaction has infinite ways to be balanced
Explanation:
To balance this equation we can use the algebraic method:
N2O4(g) + CO → NO(g) + CO2(g)+NO2(g)
Where we write each molecule as a letter:
A + B → C + D + E
Then, we write the equations according the number of atoms of each molecule. That is:
Oxygen → 4A + B = C + 2D + 2E (1)
Nitrogen → 2A = C + E (2)
Carbon → B = D (3)
Then, we have to give 1 arbitral number for a letter. For example:
B = 1; D = 1
(1) 4A + 1 = C + 2 + 2E
4A = C + 2E + 1
2A = C + E (2) Twice (2):
4A = 2C + 2E
Subtracting (1) in (2)
C + 2E + 1 = 2C + 2E
C + 1 = 2C
1 = C
Si 1 = C:
4A + 1 = 1 + 2 + 2E
4A = 2 + 2E (1)
y:
2A = 1 + E (2)
Twice:
4A = 2 + 2E

The pressure on 200 milliliters of a gas at constant
temperature is changed from 380 torr to 760 torr. The new
volume of the gas is
answerA) 100 mL
Explanation:
At constant temperature and number of moles, Using Boyle's law
Given ,
V₁ = 200 mL
V₂ = ?
P₁ = 60 kPa
P₂ = 120 kPa
The new volume of the gas is 100mL
Boyle's law is use to calculate the volume of a gas in relation with its pressure. The Boyle's law equation is as follows:
P1V1 = P2V2
Where;
P1 = initial pressure of the gas (torr)
P2 = final pressure of the gas (torr)
V1 = initial volume of the gas (mL)
V2 = final volume of the gas (mL)
According to the information of this question, the pressure on 200mL of a gas changed from 380 torr to 760 torr. Hence;
V1 = 200mL
V2 = ?
P1 = 380torr
P2 = 760torr
Using P1V1 = P2V2
V2 = P1V1/P2
V2 = (380 × 200) ÷ 760
V2 = 76000 ÷ 760
V2 = 100mL

Consider pure water separated from an aqueous sugar solution by a semipermeable membrane, which allows water to pass freely but not sugar. After some time has passed, the concentration of sugar solution: a. will have decreased b. will be the same on both sides of the membrane c. might have increased or decreased depending on other factors d. will not have changed e. will have increased
Answer:
it will be the same on both sides of the membrane
When the pure water is separated from the aqueous sugar solution when the sugar cannot pass through the semipermeable membrane. So the water moves through the membrane to the sugar solution. Therefore, the concentration of sugar solution will be decreased.
What is osmosis?Osmosis can be described as the spontaneous net movement or diffusion of solvent molecules through a permeable membrane from a region of lower solute concentration to a higher solute concentration in a direction that tends to balance the solute concentrations on both sides.
A physical process in which any solvent moves across a selectively permeable membrane separating two solutions of different concentrations.
Osmotic pressure can be described as the external pressure needed to be applied so that there is no net movement of a solvent across the membrane. Osmotic pressure can be defined as a colligative property because it depends on the molar concentration of the solute but not on its identity.
Therefore, option (A) is correct.

Answer:
26.9L of SO2
Explanation:
The reaction between Sulphur and oxygen is as follows:
[tex]S_2 + 2O_2 \to 2SO_2[/tex]
This implies that:
2 moles of oxygen reacts with 1 mole of sulphur to produce 2 moles of SO₂
2 moles of oxygen also yields 2 moles of SO₂
The number of moles of oxygen given is determined as:
[tex]= 26.9 \ L \ of \ O _2 \times (\dfrac{1 \ mol \ of O_2 }{22.4 \ L}) \\\\ = 1.20 \ mol \ of \ O_2[/tex]
