What is the atom with 10 kernel electrons and 5 valence electrons?
and
What has a + 1 charge and has 8 valence electrons in the third major energy level?

Answer:

1,103.47 milliliters

Explanation:

The total percentage of alcohol from solution A and solution B is 29. In a solution that is a mixture of solution A and B, the percentage of alcohol that would be contributed by solution A would be:--

                   11/29 x 100% = 37.93%

--while the percentage of alcohol that would be contributed by solution B would be:

               18/29 x 100 = 62.07%

Hence, if a mixture of A and B has 320 milliliters of alcohol, the amount of alcohol contributed by B would be:

                     320 x 62.07/100 =  198.624 milliliters

Now, remember that solution B is 18% alcohol. This means that the 18% alcohol content of solution B is 198.624 milliliters. Thus, the total volume of solution B would be:

                 198.624 x 100/18 = 1,103.47 milliliters.

Therefore, the total milliliters of solution B Amanda used would be 1,103.47.

The brightness of a glow stick is not directly correlated with the reaction rate of the chemicals inside the stick. Glow sticks operate based on a chemical reaction called chemiluminescence.

This reaction involves the mixing of two chemicals, usually hydrogen peroxide and a phenyl oxalate ester, with a fluorescent dye. When these chemicals mix, they react and release energy in the form of light without producing heat. The brightness of the glow stick is determined by the amount of light produced by the reaction.

The reaction rate of the chemicals inside the glow stick is affected by various factors such as temperature, concentration, and the presence of a catalyst. The reaction rate determines how quickly the chemicals react and produce light.

However, the brightness of the glow stick is not necessarily directly related to the reaction rate of the chemicals. The brightness can also be influenced by other factors such as the type and concentration of fluorescent dye used in the stick. Some dyes produce more intense colors and therefore a brighter glow, while others produce less intense colors and a dimmer glow.

In summary, while the brightness of a glow stick is a result of the chemiluminescent reaction occurring inside it, it is not directly correlated with the reaction rate of the chemicals. Other factors, such as the type and concentration of fluorescent dye used in the stick, can also influence the brightness of the glow stick.

Answer:

Liquids have characteristic properties based on the molecules they are made of. Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids. Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.

Explanation:

The identity of the noble gas is c. Ne (Neon).

To determine the identity of the noble gas, we can use the ideal gas law equation under standard temperature and pressure (STP):

PV = nRT

Where:

P = pressure (atm) at STP, which is 1 atm

V = volume (L)

n = number of moles

R = ideal gas constant (0.0821 L atm/mol K)

T = temperature (in Kelvin) at STP, which is 273.15 K

Rearranging the equation to solve for n:

n = PV / RT

Plugging in the given values:

P = 1 atm

V = 14.09 L

R = 0.0821 L atm/mol K

T = 273.15 K

n = (1 atm * 14.09 L) / (0.0821 L atm/mol K * 273.15 K)

n = 0.5827 mol

Now we need to determine the molar mass of the noble gas using the given mass and moles:

Molar mass = Mass / Moles

Plugging in the given mass:

Mass = 12.69 g

Molar mass = 12.69 g / 0.5827 mol

Molar mass ≈ 21.80 g/mol

Comparing the molar mass to the molar masses of different noble gases, we find that the noble gas with a molar mass close to 21.80 g/mol is Neon (Ne).

Therefore, the identity of the noble gas is Ne (Neon). Therefore, the correct answer is option c.

The solve this problem, we need to use the ideal gas law equation PV = north. Since we are dealing with the same temperature and pressure for both gases, we can set up a ratio using the number of moles of each gas, which is proportional to their respective masses.

The First, we need to calculate the number of moles of helium using its mass and molar mass n(He) = 12.0 g / 4.00 g/mol = 3.00 mol Next, we can use the same equation to solve for the volume of the helium PV = north V(He) = n(He)RT / P V(He) = (3.00 mol) (0.0821 Latam/Molk)(T) / (P) We don't know the exact temperature or pressure, but we can assume that they are constant for both gases. Therefore, we can eliminate them from the equation and use the ratio of the number of moles. V(Ne) / V(He) = n(Ne) / n(He) n(Ne) = 24.0 g / 20.18 g/mol = 1.19 mol V(Ne) / 14.3 L = 1.19 mol / 3.00 mol V(Ne) = (1.19 mol) (14.3 L) / 3.00 mol V(Ne) = 5.67 L Therefore, the volume that a 24.0-g sample of neon gas would occupy at the same temperature and pressure as the 12.0-g sample of helium gas is 5.67 L.

Answer:

Because of gravity and as a result, created planets and stars.

(Likely by a nearby supernova shockwave also)

Although I'm not an expert, I seem to recall reading that solar systems often begin with clouds of unorganized matter measuring 20 parsecs (65 light years) across. Most of them are hydrogen molecules. The pressure required to hold the molecules together increases with temperature, but because the typical temperature is around 12 k, the pressure is negligible. It originates from the gravity of the cloud itself. Material from novas, colliding neutron stars, and high-speed material jets emerging from stars and black holes all contribute to the continuous enrichment of such clouds. That adds those heavy elements—like gold—that can only be produced by the rapid neutron capture (rNC) process as opposed to the simple nuclear fusion process (slow neutron capture). These clouds spontaneously emerge from floating pieces of material, hold together for millions of years, and eventually disperse. A component of the cloud condenses along the route for a variety of causes, including localized concentrations of greater density or shock waves from supernovae. Unbalances in the cloud lead it to split up when condensation takes place. Then those fragments shatter once again, leaving you with barely enough for a solar system. It would have been within 3.5 light years of the initial cloud for our galaxy. The contraction up to this point has been isothermal, which means that heat is being radiated so quickly that temperature stays mostly unchanged. The creation of a Bonnor-Ebert sphere comes next. Although such zones frequently appear in photographs in a faint manner, this is only a hypothetical area in which there is a certain amount of mass. The First Hydrostatic Core is located here (FHSC or First Core). The First Core can be imagined as a pre-proto Sun with an interior temperature of roughly 300 k and a radius of 1 AU (the same as the Earth's orbit) (26.85 C or 80.33 F). Although it first begins off chilly, it ultimately warms up to 300 k and then grows even hotter over the course of years. The friction of falling materials and adiabatic contraction provide the heat (the kind that makes things hotter). Hydrogen molecules start to break down into atomic hydrogen, which is more dense and falls to the center, at temperatures between 1500 k and 2000 k, on average. Eventually, the atomic hydrogen coalesces into a protostar-sized Second Core. Because the entire system is rotating swiftly and because momentum is being lost in some areas owing to gas shooting off, an accretion disk has already formed. Although in our instance it would have also been a protoplanetary disk, the disk is a protostellar disk. The protostar is regarded as a star until it becomes hot and brilliant enough to begin ejecting the gas and dust. (Prior to it, infalling gas and dust are still adding mass to the protostar.)

In the nebular hypothesis, the collapse of the nebula is believed to have been triggered by a disturbance or shock wave, such as a nearby supernova explosion or the gravitational influence of a passing star or gas cloud.

This disturbance caused the nebula, which was a large and diffuse cloud of gas and dust in space, to start collapsing under the force of its own gravity. As the nebula contracted, its particles came closer together, and the conservation of angular momentum caused it to spin faster.

The collapse and spin eventually led to the formation of a rotating protostellar disk at the center, which eventually evolved into a young star, while the surrounding material formed planets and other celestial bodies through accretion and gravitational attraction.

Answer:

Resource distribution plays a significant role in shaping the world we live in. Uneven distribution of resources such as food, water, energy, and raw materials can lead to various consequences such as population distribution, human migration, and trade.

Population distribution: The uneven distribution of resources can lead to the unequal distribution of people. People tend to settle in areas where resources are abundant, such as near water sources, fertile land, and mineral-rich regions. For example, many coastal cities have high population density due to easy access to water, fishing, and shipping opportunities. On the other hand, areas with scarce resources such as deserts, mountains, and polar regions have lower population density.

Human migration: Resource distribution is also a significant factor that drives human migration. People move from one place to another in search of better opportunities, such as jobs, education, and a better quality of life. For instance, rural people may migrate to urban areas in search of jobs, while people in resource-poor regions may migrate to resource-rich areas to improve their livelihoods. Climate change and natural disasters may also cause migration, such as people moving from drought-affected regions to regions with better water availability.

Trade: The distribution of resources also affects trade between regions and countries. Countries with abundant natural resources such as oil, gas, and minerals can export them to other countries, generating revenue and creating jobs. On the other hand, countries with scarce resources may import them from other countries, creating trade relationships. Trade allows countries to specialize in producing goods and services in which they have a comparative advantage and trade them for goods and services they do not produce efficiently.

In conclusion, the distribution of resources has a significant impact on various aspects of our lives, including population distribution, human migration, and trade. Unequal distribution of resources can lead to inequality and conflict, while a balanced distribution can promote economic growth and stability.

Mitosis is conventionally divided into 5 phases, which include prophase, prometaphase, metaphase, anaphase and telophase and cytokinesis.

Interphase

Before coming into mitosis, a mobile spends a length of its increase underneath interphase.

Prophase

Prophase straight away follows the S and G2 levels of the cycle and is marked by way of condensation of the genetic fabric to form compact mitotic chromosomes composed of  chromatids attached at the centromere.

Prometaphase

In the prometaphase, the nuclear envelop disintegrates. Now the microtubules are allowed to extend from the centromere to the chromosome.

Metaphase

At this level, the microtubules start pulling the chromosomes with equal pressure and the chromosome ends up in the center of the cell. This area is referred to as the metaphase plate.

Anaphase

The splitting of the sister chromatids marks the onset of anaphase. These sister chromatids end up the chromosome of the daughter nuclei.

Telophase

The chromosomes that cluster at the two poles start coalescing into an undifferentiated mass, because the nuclear envelope begins forming round it.
