Why does c14 have 8 neutrons?

Answers

Answer 1

C14 have 8 neutrons, because C have 6 atomic number and it have 14 atomic mas , where atomic mass is total of proton and neutron so the neutron of C14 is 8.

It is commonly known that Carbon-14 is an isotope of carbon. It is also known as a neutral atom. Additionally, the ratio of neutrons to protons varies among different isotopes.

The total number of protons that make up an atom's nucleus is represented by the atomic number of that atom, as is well known. We know that carbon has an atomic number of 6, a mass number of 14. It is common knowledge that mass is the product of protons and neutrons. There will thus be = 14 - 6 = 8 neutrons.

Be as explicit as you can in describing how the covalent bond between an atom of Chlorine and an atom of Iodine forms. (What happens to the electrons, which electrons are involved, and what allows this to happen MUST all be part of your answer to receive full credit.)

Answers

When two atoms of chlorine and iodine join together to form a covalent bond, their outermost electrons interact to form a chemical bond.

What is a Covalent bond?

A covalent bond is a type of chemical bond that involves the sharing of a pair of electrons between two atoms. Covalent bonds are formed when two atoms come together to share their electrons in order to reach a more stable electron configuration. As a result, the two atoms become bonded together by the attraction of their shared electrons.

The chlorine atom has seven valence electrons, while the iodine atom has seven as well. Both atoms will want to complete their octets, so the two atoms share their outermost electrons with each other. During the formation of the covalent bond, the chlorine atom will donate one of its electrons to the iodine atom, while the iodine atom will donate one of its electrons to the chlorine atom. This sharing of electrons allows the two atoms to form a single bond and fill their octets, forming a covalent bond.

What is molar ratio?

The difference between the moles (or molecules) of reactants consumed and the moles (or molecules) of products produced in a chemical reaction is known as the molar ratio.

i) Now given the molar ratio of CV : NaOH is 1:1 . That means Equal moles of CV and NaOH are present in the solution. That means all the CV and NaOH molecules will react to form equal number of products.

So in this case, no reactant will be left as all of them have been converted to product after completion of reaction.

ii) In this case, the given NaOH : CV = 1000 : 1. That means per 1000 moles of NaOH, we have only 1 mole of CV. Now since 1 mole of CV can react with only 1 mole of NaOH, then after the reaction of this 1 mole CV, there will be no CV left . And only 999 NaOH molecules will be left in the solution

So here % CV left = 0%

A sample of nitrogen is heated from STP to 100°C at constant pressure. Calculate the volume at 100°C.

Answers

Considering the Charles' law and STP conditions, the volume at 100°C is 30.60 L.

Charles' law

Charles' law establishes the relationship between the volume and the temperature of a sample of gas at constant pressure and establishes that when the temperature is increased the volume of the gas also increases and that when cooling the volume decreases.

Mathematically, Charles's law is expressed as:

V÷T=k

where:

V is the volume.

T is the temperature.

k is a constant.

Analyzing an initial state 1 and a final state 2, it is fulfilled:

V₁÷T₁= V₂÷T₂

STP conditions

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Volume at 100°C

In this case, you know:

V₁= 22. 4 LT₁= 0°C= 273 KV₂= ?T₂= 100 °C= 373 K

Replacing in Charles' law:

22.4 L÷ 273 K= V₂÷ 373 K

(22.4 L÷ 273 K)× 373 K= V₂

30.60 L= V₂

Answers

Lystrosaurus and Glossopteris are two pieces of fossil evidence support the idea of continental drift.

One of the geologist's first theories about how continents moved over time was continental drift.  The science of plate tectonics has been largely supplanted the hypothesis of the continental drift. Alfred Wegener has been most closely associated with the continental drift idea. Wegener released a paper in the early twentieth century describing his notion that continental landmasses were "drifting" across the Earth, occasionally ploughing through seas and into one other. He developed the term "continental drift" to describe this process.

Wegener found similarities in the coasts of eastern South America as western Africa and hypothesised that those countries had originally been part of a supercontinent called Pangaea, which had separated and travelled many kilometres away over geologic time. He also mentioned nearly comparable fossil creatures and rock layers that happened on vastly different continents. Colbert discovered Lystrosaurus fossils in the Transantarctic Mountains of Antarctica. Such fossils belonged to something like a species previously discovered in Africa, proving that the world's two most distant continents were formerly linked.

Answers

The estimated time of death is approximately 10:30 pm the night before.

Estimating the time of death (TOD) can be a complex process, and the methods used will depend on the specific circumstances of the case. Some of the factors that may be taken into consideration include:

The stage of decomposition of the body: As a body decomposes, it will go through several distinct stages, each of which can provide information about the TOD.The temperature of the body: As a body cools after death, the temperature will drop at a predictable rate. By measuring the temperature of the body at different points in time, it may be possible to estimate the TOD.The body's position: The position of the body can provide clues about the time that has passed since death. For example, if a body is found lying on its back, it may indicate that it has been dead for a longer period of time than if it is found on its stomach.The presence of insects or animals: Certain insects and animals are attracted to dead bodies at different stages of decomposition. By examining the presence of these insects or animals, it may be possible to estimate the TOD.Scene examination: The scene examination and any possible evidence collected can give a rough estimate of the time of death.

It is important to note that estimating the TOD is not an exact science and there are often significant margins of error. A professional forensic examination is typically needed to determine the TOD.

Avogadro's constant, 6.022 1023, and the molar mass of the material are used to calculate the number of molecules in a given mass of the substance. Aspartame's molecular formula is C14H18N2O5.

Aspartame has a molecular mass of 294 (12 * 14 + 1 * 18 + 14 * 2) + 16 * 5)

Let's convert the 10 mg mass supplied to aspartame moles as follows:

Amount of moles =

= 0.034 × 10 ⁻⁵ mole

We may convert this number to molecules using Avogadro's constant as follows:

= 0.034 × 10 ⁻⁵ (6.022 × 10²³)

= 0.034 × 10¹⁹

Force between dipoles:                                                                                     Hydrogen chloride (HCl), hydrogen fluoride (HF), and water are all examples of dipole-dipole (H2O) forces shown below. HCl (hydrogen chloride): HCl is a permanent dipole. Chlorine atoms are partially negatively charged and hydrogen atoms are partially positively charged. Dipole-induced dipole force:                                                                  Reaction of hydrogen chloride (HCl) and argon (Ar). In this type of interaction, positively charged hydrogen (H) atoms of one HCl molecule attract electrons from Ar atoms, and negatively charged Cl atoms of another molecule attract Ar nuclei. As a result, Ar develops a dipole moment.                                                                                           Other examples: water with xenon, water with oxygen.                                             London Dispersion Force:                                                                   Consider the London dispersion force between two chlorine molecules. Here both chlorine atoms are connected by a covalent bond. A covalent bond is formed by sharing the valence electrons evenly between two chlorine atoms.                                                                                                      Other examples: Ne, Ar.

Consider the feedback loop that occurs when you je rk your hand away from something hot. How does this reflex help to maintain homeostasis?

Answers

Considering the feedback loop that occurs when you quickly remove your hand away from something hot, this reflex helps to maintain homeostasis by ensuring that the body is free from danger and thus maintains the internal condition of the body.

What is homeostasis?

The stable internal, external, and chemical conditions that are maintained by living systems are known as homeostasis. In order for the organism to function at its best, a number of factors, including body temperature and fluid balance, must be maintained within predetermined ranges.

The body's reflexes help to maintain homeostasis in the body such as heart rate, breathing rate, blood pressure, and digestion.

Some reflexes that maintain homeostasis in the body include:

swallowing,sneezing,coughing, andvomiting
