Explanation:A neutral atom has an equal number of electrons and protons. When an electron is lost, the atom becomes positively charged and is called a cation. On the other hand, when an electron is gained by an atom, it becomes negatively charged and is called an anion. The distance of the nucleus of an ion and the valence electron is referred to as the ionic radius.

Answer:

V₂ = 0.5 L

Explanation:

Given that,

Initial volume, V₁ = 2.5 L

Pressure, P₁ = 350 kPa

New pressure, P₂ = 1750 kPa

We need to find the new volume if the temperature remains constant. The mathematical relation between P and V is :

\(P\propto \dfrac{1}{V}\\\\or\\\\\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\)

Where

V₂ is new volume

So,

\(V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{350\times 2.5}{1750}\\\\V_2=0.5\ L\)

So, the new volume is equal to 0.5 L.

The Ag\(_{2}\)CO\(_{3}\)   is formed when 25.0 ml of 0.200M AgNO\(_{3}\) is mixed with 50.0 ml of 0.800 M Na\(_{2}\)CO\(_{3}\) is 0.68 g.

According the question , the chemical equation is give by :

2AgNO\(_{3}\)   +   Na\(_{2}\)CO\(_{3}\)  ------->   Ag\(_{2}\)CO\(_{3}\)     +      2NaNO\(_{3}\)

Given that :

volume of silver nitrate = 25.0 ml or 0.025 L

molarity M =  0.200 M

volume of sodium carbonate = 50.0 ml or 0.050 L

molarity = 0.800 M

now, no. of moles of silver nitrate  =  0.025 × 0.200 = 0.005 moles

no. of mole of sodium carbonate = 0.050 × 0.800 =  0.04 moles

the no. of moles of silver carbonate ,  =  0.5 × 0.005

                                                                =  0.0025 moles

molar mass  of Ag\(_{2}\)CO\(_{3}\) = 275.7 g/mol

therefor, the mass of Ag\(_{2}\)CO\(_{3}\) =   0.0025 moles × 275.7 g/mol

                                                 =0.68 g

The chemical pathway appears to be important both in some types of psychotic behavior and in the reinforcing properties of various drugs is  Mesolimbic dopamine pathway.

The reinforcing and addictive qualities of substances like nicotine are greatly influenced by the mesolimbic dopamine system.

Dopamine serves a variety of functions and is both a neurotransmitter and a hormone.

These mesolimbic pathways aid in the distribution of dopamine throughout the body. The nucleus accumbens receives dopamine from the ventral tegmental region via the mesolimbic dopamine pathways.

Dopamine produces a sense of reward and pleasure in the nucleus accumbens.

Dopamine flows from the ventral tegmental region to the nucleus accumbens anytime there is a sense of rewarding or pleasurable stimuli. Dopamine provides a sense of positive feeling, which leads to addictive behavior ( ie, drugs).

To determine the pH of a solution using a pH indicator paper, you need a color chart or a color scale that corresponds to different pH values.

This color chart or scale is used to compare the color of the pH indicator paper after it has been immersed in the solution. The pH indicator paper is impregnated with a universal pH indicator, which is a chemical compound that changes color depending on the acidity or alkalinity of the solution.

The indicator undergoes a chemical reaction with the hydrogen ions (H+) or hydroxide ions (OH-) present in the solution, resulting in a color change.

By comparing the color of the pH indicator paper with the color chart or scale, you can determine the approximate pH of the solution. The color chart usually provides a range of colors corresponding to different pH values, allowing you to match the observed color to the nearest pH value.

In the hypothesis mentioned, the aim is to calibrate a cabbage pH indicator using the pH values obtained from a universal pH indicator. Therefore, in addition to the pH indicator paper and color chart, you would also need a range of solutions with known pH values to establish a calibration curve specific to the cabbage pH indicator.

In summary, to determine the pH of a solution using a pH indicator paper, you need a color chart or scale that correlates the observed color of the pH indicator paper with different pH values. This chart or scale serves as a reference for interpreting the color change and determining the pH of the solution.

That the pressure doubles when the gas's volume is cut in half.

If gas volume and temperature are maintained constant, the formula demonstrates that pressure and volume are inversely proportional.

This implies that if volume decreases, pressure must increase. This implies that if pressure doubles, volume must be half, and if pressure is halved, volume must be doubled in order to maintain the K value.

If the volume is doubled and the pressure is tripled, the effect on the temperature will be 3 2 = 6 times. This is because for perfect gases, the temperature is directly related to both the volume and the pressure.

The product of the complete combustion of the molecule C3H8 is carbon dioxide and water.

C3H8 is the chemical formula for propane, a common fuel used in many applications such as heating, cooking, and transportation. When propane is burned in the presence of oxygen, it undergoes complete combustion, producing carbon dioxide and water as the only products. The balanced chemical equation for the complete combustion of propane is:

C3H8 + 5O2 → 3CO2 + 4H2O

In this equation, the coefficient of C3H8 is 1, indicating that one molecule of propane is needed for the reaction to occur. The coefficient of oxygen is 5, indicating that five molecules of oxygen are required. The products of the reaction are three molecules of carbon dioxide and four molecules of water, which are released as gases.

In summary, the complete combustion of propane, represented by the chemical formula C3H8, produces carbon dioxide and water as the only products, with the balanced equation C3H8 + 5O2 → 3CO2 + 4H2O.

The amounts of concentrated HCl, water, and acetone needed can be calculated based on the desired final concentration of HCl and the volume and composition of the solvent.

To prepare 100 mL of solvent with 1.2 M HCl in 65% acetone, we need to use the following formula:

% acetone/100 × volume of solvent = volume of acetone

% HCl/12 M × volume of solvent = volume of concentrated HCl

volume of water = volume of solvent - volume of acetone - volume of concentrated HCl

Substituting the given values into the formula:

65/100 × 100 mL = 65 mL acetone

1.2/12 M × 100 mL = 10 mL concentrated HCl

Volume of water = 100 mL - 65 mL - 10 mL = 25 mL water

Therefore, to prepare 100 mL of solvent with 1.2 M HCl in 65% acetone, we need 10 mL concentrated HCl, 65 mL acetone, and 25 mL water.

This problem is describing a mixture composed by diethyl ether and actic acid, in which it is desired to extract the latter somehow.

In this case, it turns out relevant to recall the concept of polarity, hydrogen bonds, and, in general, intermolecular forces. Acetic acid is a highly polar compound, able to have both dipole and hydrogen-bonding interactions, which are by far stronger than nonpolar-based London dispersion forces.

In such a way, since diethyl ether and actic acid are able to interact via dipole-dipole interactions, they latter is able to be dissolved in the former; however, when it is desired to extract the acid, it would be necessary to add a substance able to form H-bonds with acetic acid, which are stronger than the dipole interactions.

Therefore, the best solvent for this extraction will be water due to its higher polarity and superior capacity to form H-bonds.
