The identity of the daughter nuclide from the positron emission of c-11/6 is option c)11/5-b
What is beta decay?
In the radioactive decay process known as beta decay, a parent nucleus emits an electron (or positron). An electron and a neutron can separate from certain neutrons in the parent nucleus. The parent nucleus will emit an electron, followed by the production of a further proton, increasing the atomic number. In terms of nuclear physics, some elements in group A can form daughter nuclei of elements that are next to them in the periodic table. Let's call it B in this situation.:
NZA→ 0−1e+NZ+1BZNA→ −10e+Z+1NB
where:Z is the atomic number,N is the mass number
If the emission is a positron, then the process is:
NZA→ 0+1e+NZ−1BZNA→ +10e+Z−1NB
So from the following equation we learn
11(top) 6(bottom) C ---> 0(top) 1(bottom) e + 11(top) 5(bottom) B
Therefore the identity of the daughter nuclide from the positron emission of c-11/6 is option c)11/5-b

Draw lewis structure for C5H12
The Lewis structure for C5H12 looks like this:
H - C - H
| | |
H - C - H
| | |
H - C - H
A Lewis structure is a way of representing the covalent bonds in a molecule. To draw the Lewis structure for C5H12, we first need to determine the number of valence electrons in the molecule. The valence electrons are the electrons in the outermost energy level of an atom, and they are the ones involved in chemical bonds.
In the case of C5H12, carbon has four valence electrons and hydrogen has one. This means that the molecule has a total of 5 x 4 + 12 = 32 valence electrons.
To draw the Lewis structure, we start by placing the five carbon atoms in the center of the structure, forming a pentagon. We then connect each carbon atom to the other four using single bonds, which represent two electrons each. This accounts for 20 of the 32 valence electrons.
Next, we add the remaining 12 valence electrons by placing hydrogen atoms on the outside of the pentagon, one on each side. Each hydrogen atom forms a single bond with a carbon atom, accounting for the remaining 12 valence electrons.

Why do some bodies in the Solar System maintain countless well-preserved indications of impacts on their surface
even after many millions of years? Give some examples and explain in detail how at least 2 factors contribute to this
Answer:
There are several factors that contribute to the preservation of impact craters on the surface of bodies in the Solar System.
One factor is the lack of erosion or weathering on these bodies. Many of the bodies in the Solar System, such as the Moon and many of the outer planets' moons, do not have atmospheres or hydrospheric systems (like oceans, lakes, or rivers) that can erode or weather the surface over time. This means that the surface of these bodies is not subjected to the same types of processes that can wear away or smooth out surface features on Earth. As a result, impact craters and other surface features can remain well-preserved for millions of years.
Another factor that can contribute to the preservation of impact craters is the presence of a surface layer of material that is resistant to erosion. For example, on the Moon, the surface is covered by a layer of fine-grained dust called regolith, which is made up of small rocks and particles that have been ground up by impact and other processes. This regolith layer is relatively soft and easily disturbed, but it also acts as a protective layer that can preserve the underlying surface features. Similarly, on some of the outer planets' moons, there may be a layer of ice or other materials that can act as a protective layer and preserve impact craters and other surface features.
Examples of bodies in the Solar System that have well-preserved impact craters include the Moon, Mars, and many of the outer planets' moons, such as Europa and Ganymede. The lack of erosion and the presence of protective surface layers on these bodies have allowed them to maintain countless well-preserved indications of impacts on their surfaces even after many millions of years.
Explanation:
To solve this, we must know each and every concept behind solar system. Therefore, impact craters enable scientists to investigate the geological history of a planet.
What is solar system?The Solar System is composed of the Sun and the objects that orbit it. It was created by the gravitational collapse of a massive interstellar molecular cloud 4.6 billion years ago. The Sun contains the vast bulk of the system's mass (99.86%)
Several processes contribute to the preservation of impact craters on the surfaces of Solar System worlds. The absence of erosion or weathering on these bodies is one cause. Another aspect that can aid in the preservation of impact craters is the existence of an erosion-resistant surface layer of material.

The study of how electromagnetic radiation is absorbed, emitted, and scattered by atoms and molecules-whether they are in the gaseous, liquid, or solid phase-is known as spectrum spectroscopy. Although the terms light, radiation, and electromagnetic radiation can all be used interchangeably, visible electromagnetic radiation is referred to as light. In Activities 1 and 2, you will learn about various characteristics of electromagnetic radiation. Understanding molecular characteristics and the outcomes of spectroscopic studies requires spectroscopy, which was essential in the development of quantum mechanics. To make the subject more tangible and less abstract and technical, it serves as a "stepping stone" to introduce us to the ideas of quantum mechanics and the quantum mechanical explanation of molecular features. A spectrum is a graph that shows how an atomic or molecular system responds to specific wavelengths of radiation or the intensity of the radiation at those wavelengths. An absorption spectrum shows how much light is absorbed by a material at each wavelength of radiation. The three most popular ways to visualize an absorption spectrum are as a plot with either the transmission (T), absorbance (A), or absorption coefficient on the y-axis and the wavelength on the x-axis. The optical density is another name for the absorbance. If we use the definitions of I0 (amount of light striking a sample), I (amount of light the sample transmits), and d (thickness of the sample).

Where is blood under greatest pressure? A) arteries B) capillaries C) veins D) lymph vessels
The greatest blood pressure is found in
A) Arteries
Arteries are the blood vessels that take oxygenated blood from the heart to other parts of the body. Though these are the primary blood vessels that carry blood and have a considerable diameter they have the highest blood pressure due to the force with which the blood is pumped by the heart
Capillaries have a diameter of 8-10μm such that only RBC's and small proteins are able to pass through them while the white blood cells (WBC's ) move around as extracellular fluid.
Veins are primary blood vessel that carry the deoxygenated blood from various parts of the body to the heart. The blood pressure present in veins is comparatively lower in comparison to that of arteries as they transport blood against the force of gravity.
Lymph vessels are primary vessels that allow for the transport of Lymphatic fluid. Though being similar to arteries they do not have high pressure due to the lack of the force exerted by the heart.

a mixture of 100 g of k2cr2o7 and 200 g of water is stirred at 60 oc until no more of this salt dissolves. the resulting solution is decanted (poured off) and cooled to 20 oc. what mass of k2cr2o7 crystallizes from the solution during the cooling?
A mixture of 100 g of K2Cr2O7 and 200 g of water is stirred at 60 OC until no more of this salt dissolves. 33% mass of K2Cr2O7 crystallizes from the solution during the cooling.
To solve this problem, you need to use the solubility curve for potassium dichromate (K2Cr2O7) in water. A solubility curve is a graph that shows the relationship between the temperature of a solution and the amount of a substance (in this case, potassium dichromate) that will dissolve in the solution. Since the mixture you have consists of 100 grams of potassium dichromate and 200 milliliters of water, you can use the solubility curve to determine how much potassium dichromate will dissolve in the mixture at 60 degrees Celsius.
At a temperature of 60 degrees Celsius, the solubility of potassium dichromate in water is approximately 150 grams per 100 milliliters of water. Since the mixture you have consists of 100 grams of potassium dichromate and 200 milliliters of water, you can use the solubility curve to determine how much potassium dichromate will dissolve in the mixture.
Since the volume of water in the mixture is 200 milliliters, this means that approximately 67% of the potassium dichromate in the mixture will dissolve at 60 degrees Celsius. The remaining 33% of the potassium dichromate will not dissolve in the mixture and will remain as a solid.
When the mixture is cooled to 20 degrees Celsius, the solubility of potassium dichromate in water decreases. This means that some of the potassium dichromate that was dissolved in the mixture at 60 degrees Celsius will crystallize out of the solution as the temperature decreases.
To determine the mass of potassium dichromate that crystallizes from the solution during the cooling, you can use the following equation:
Mass of potassium dichromate crystallized = (Mass of potassium dichromate in mixture - Mass of potassium dichromate dissolved at 60 degrees Celsius) x (1 - Solubility at 20 degrees Celsius / Solubility at 60 degrees Celsius)
Substituting in the values from the problem, we get:
Mass of potassium dichromate crystallized = (100 grams - (100 grams x 67%)) x (1 - (Solubility at 20 degrees Celsius / 150 grams)

What are polyprotic acids?
Polyprotic Acid is a chemical that can donate more than one proton. Diprotic and Triprotic are two distinct varieties of polyprotic acid that can, respectively, donate two and three protons.Depending on how frequently dissociation takes place, polyprotic acids have a variety of dissociation constants, including Ka1, Ka2, Ka3, and equivalence points.Given its ability to provide an aqueous solution with two hydrogen atoms, sulfuric acid (H2SO4) is a polyprotic acid. In particular, the fact that sulfuric acid has two hydrogen atoms available makes it a diprotic acid.A triprotic acid is orthophosphoric acid (H3PO4).To know more about polyprotic acids, click the link given below:

predict whether the so2 and so3 are polar or nonpolar molecules.
SO2 is polar and SO3 is non - polar because of substituent differences and especially because of geometry.
What are polar and non polar molecules?When things are different at each end then we call them as polar. Some molecules have both positive and negative ends, then we call them polar. If they don't have then we call them non-polar. Things that are polar attract and repel each other.
As SO2 is bent, therefore the dipoles do not cancel and the molecule is polar. The difference in electronegativity between sulfur and oxygen is enough for dipole moments to form but the geometry of sulfur trioxide cancels their effects, making the molecule a nonpolar.
