which of the following best describes a result of the polar nature of water molecules? water molecules repel each other. the volume of water decreases by nearly half when it is frozen. water molecules repel most other substances. ionic compounds dissolve easily in water.

Answers

Answer 1

In water, ionic substances dissolve quickly. This sentence outlines how water molecules are polar nature. A polar covalent molecule is water.

Due to the unequal sharing of electrons between the atoms and the molecule's (side) asymmetrical structure, a water molecule has two poles: a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole. The water molecule has a curved form, which means that the majority of the negative charge from the oxygen is on one side of the molecule and on the other atoms positive charge from hydrogen is present. As a result, the water molecule can be described as polar.

the absolute temperature of a sample of monatomic ideal gas is doubled at constant volume. what effect, if any, does this have on the pressure and density of the sample of gas?

Answers

The absolute temperature of a sample of monatomic ideal gas is doubled at constant volume. The effect, if any, does this have on the pressure and density of the sample of gas is doubled and remains the same.

The ideal gas equation is given that :

P V = n R T

where,

P = Pressure

V = volume

n = no. of moles

R = gas constant

T = temperature

it is clear from the above equation that if we doubled the temperature of the gas the pressure of the gas is also doubled because they are directly proportional to each other. the density is given as :

density = mass / volume

it is clear that density is only depends on the mass and the volume so, it will remains the same.

Answers

The molarity of the resulting solution is 0.65 M.

Which molarity is it?To be able to comprehend what we mean by the molarity of a solution, we must first go back in time. We are aware that molarity refers to the concentration of the component in the solution. In this situation, it's important to be aware that the molarity can only be represented in terms of moles per litre.The number of moles of the gas must now be determined, and this can only be done by applying the ideal gas equation, which is what we will be able to accomplish in this issue.

PV = nRT

Pressure is P.

Volume is V.

The number of moles is n.

Solvents can be categorized as organic or inorganic and in terms of chemical polarity. Polar solvents include water, alcohols, and other chemicals containing –OH, such as acetic acid, which have the ability to donate H+ and form hydrogen bonds. Polar solvents lacking the –OH group, including acetonitrile, dimethylformamide, and dimethylsulfoxide, are protophilic solvents and are used to dissolve less polar solutes.

The concomitant presence of a suitable amount of bromine in CCI, phase raises the rate and yield significantly.

The difference between the ranges of the strong nuclear force and the coulomb force that holds atomic nuclei together is the nuclear force, the tight force between nucleons.

At very short distances, nuclear forces repel, keeping protons and neutrons from getting too close to each other. The strong force holds together quarks, the elementary particles that make up the protons and neutrons of the atomic nucleus, and further holds the protons and neutrons together into the atomic nucleus.

As such, it is responsible for the underlying stability of matter. The nuclear force arises from the exchange of virtual optical mesons, such as virtual pions, and two types of virtual mesons with spin (vector mesons), rho mesons and omega mesons.

Answers

One mole or 180 g of glucose contains 72 g of carbon. Thus, 37.5 g of glucose contains 15 g of carbon.

What is glucose?

Glucose is the basic monomer sugar unit which polymerises to form carbohydrates. The formula of glucose is C₆H₁₂O₆. Glucose is formed by the combination of water and carbon dioxide.

The atomic mass of carbon = 12 g/mol

molar mass of C₆H₁₂O₆ = 180 g/mol.

C₆H₁₂O₆ contains 6 carbon atoms.

Thus, mass of 6 carbons = 6 × 12 g = 72 g

Hence, 180 g of  glucose contains 72 g of carbon.

Now the mass of glucose which contain 15 g of carbon is :

=  (15g × 180 g) / 72 g

For example, the electron configuration of Vanadium in its neutral state is [Ar] 3d^3 4s^2.

which types of fossil fuels emit the highest amounts of co2 per unit of energy produced? which types produce the least? geol 1305

Answers

Compared to burning natural gas or petroleum, coal combustion produces more carbon dioxide.

Natural gas produce the least CO2.

The primary source of most emissions of greenhouse gases (GHG) that are created by humans is the burning of fossil fuels like coal, natural gas, and petroleum for energy.

The basic components of fossil fuels are carbon and hydrogen. When fossil fuels are burned, oxygen reacts with both carbon and hydrogen to create CO2 and water (H2O). Coal emits the highest amount of CO2.

We use the heat produced by these reactions as energy. The fuel's carbon content determines how much CO2 is generated (emitted), while the fuel's hydrogen and carbon contents determine how much heat is generated.

Natural gas combustion creates less CO2 than burning other fossil fuels because natural gas, which is primarily composed of CH4, has a high hydrogen concentration.

if a small weather balloon with a volume of 42.0 l at a pressure of 1.00 atmosphere was deployed at the edge of typhoon odessa, what was the volume of the balloon when it reached the center?

Answers

The volume of the balloon at the center of the typhoon is 43.75L.

The low atmospheric pressure at the core of a tropical storm affects how powerful it is. Typhoon Odessa, which made landfall in the Pacific Ocean in August 1985, had winds that could reach 90 miles per hour and a pressure that was 40.0 mbar lower at the centre than the surrounding atmosphere. When Hurricane Andrew (shown), which had winds of up to 165 mph, struck south Florida, its central pressure was 90.0 mbar lower than its surroundings.

It is presumed that the temperature is constant because no variations were mentioned. Therefore, the new volume at the core of Typhoon Odessa is calculated using Boyle's law, which explains the relationship between pressure and volume. According to Boyle's law, P1V1 = P2V2 in mathematics.

If we assume that 1 bar = 1 atm, 1 mbar = 0.001 atm, and 40 mbar = 0.040 atm

P1=1.0 atm, V1=42.0 litres, P2=1 atm - 0.040 atm = 0.960 atm, and V2=?

Employing P1V1 = P2V2

V2 = P1V1/P2

V2 = 1.0 * 42.0 / 0.96

V2 = 43.75L

Consequently, the balloon at the typhoon's core has a 43.75 L volume.

What is the half-life of carbon 14?

Answers

5700 ± 30 years

Carbon 14 is an isotope of carbon, which has longest life amongst the three isotopes of carbon but very low abundance as compared to the other isotopes of carbon.

Carbon-14 nucleus has six protons and eight neutrons, for an atomic mass of 14.

It is a radioactive isotope of carbon.

Its half life is too high which makes it useful for dating in archaeology and to know age of fossils.

Carbon-14 decays slowly in a living organism. After the organism dies, it ceases to absorb carbon-14, such that the amount of the isotope in the tissues of decayed organisms decreases.

It has a half-life of 5,730 ± 30 years which means half of the amount of the isotope present at any instant will undergo disintegration during the next 5,730 years.

Carbon-14 decays at a constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its leftover  carbon-14.
