If 15.0 liters of neon at 25.0oc is allowed to expand to 45.0 liters, what must the new temperature be in celsius to maintain constant pressure? (3 sig figs for answer)

Answers

Answer:

621.3°C

Explanation:

To find the new temperature of the neon gas after it expands from 15.0 liters to 45.0 liters, you can use the Ideal Gas Law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. If the pressure is constant, then P remains constant, so the relationship between volume and temperature can be expressed as:

V1/T1 = V2/T2

where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.

Substituting the initial values:

V1 = 15.0 liters

T1 = 25.0°C + 273.15 = 298.15 K

And the final values:

V2 = 45.0 liters

We can solve for T2:

T2 = T1 * (V2/V1) = 298.15 K * (45.0 liters / 15.0 liters) = 894.5 K

Finally, we can convert T2 back to Celsius:

T2 = 894.5 K - 273.15 = 621.3°C

In conclusion, if 15.0 liters of neon at 25.0°C is allowed to expand to 45.0 liters, the new temperature must be 621.3°C in order to maintain constant pressure.

to what volume should you dilute 130 ml of an 7.90 m cucl2 solution so that 50.0 ml of the diluted solution contains 4.53 g cucl2 ?

Answers

To dilute 130 mL of 7.90 M CuCl2 to 1257 mL to obtain a solution that contains 4.53 g of CuCl2 in 50.0 mL of solution.

What is molarity?

Molarity is a unit of concentration that is widely used in chemistry. It is defined as the number of moles of solute per liter (L) of solution.

Calculation

To dilute 130 mL of a 7.90 M CuCl2 solution so that 50.0 mL of the diluted solution contains 4.53 g CuCl2, you need to determine the moles of CuCl2 in 50.0 mL of the diluted solution and then calculate the final volume of the solution.

First, convert 4.53 g of CuCl2 to moles:

4.53 g / (111.00 g/mol) = 0.0407 moles

Next, calculate the molarity of the diluted solution:

0.0407 moles / 0.05 L = 0.814 M

Finally, multiply the initial volume (130 mL) by the ratio of the initial molarity (7.90 M) to the final molarity (0.814 M) to find the final volume:

130 mL * (7.90 M / 0.814 M) = 130 mL * 9.68 = 1257 mL

While a low PaCO2 indicates alveolar hyperventilation, an increased PaCO2 indicates alveolar hypoventilation. The pH will be changed by abrupt changes in PaCO2. In general, a respiratory acidosis is indicated by a low pH and a high PaCO2, whereas a metabolic acidosis is indicated by a low pH and a low PaCO2.

Answers

The vapor pressure of a solution of 0.114 mol of cholesterol in 6.72 mol of toluene at 32 degree is 40.6Torr.

The Raoult's Law equation may be used to determine the solution's vapour pressure:

Vapor Pressure of Solution = (Mol Fraction Cholesterol * Vapor Pressure Cholesterol) + (Mol Fraction Toluene * Vapor Pressure Toluene)

Mol Fraction Cholesterol =[tex]\frac{0.114}{ (0.114 + 6.72) }= 0.016[/tex]

Vapor Pressure Cholesterol = 0 (Cholesterol has no vapor pressure)

Mol Fraction Toluene =[tex]\frac {6.72}{(0.114 + 6.72)} = 0.984[/tex]

Vapor Pressure Toluene = 41 Torr

Vapor Pressure of Solution =[tex](0.016 * 0) + (0.984 * 41) = 40.6 Torr[/tex]

Therefore vapour pressure of solution is 40.6Torr.

one cheeseburger has 340 kcal and 25 grams of fat. what percentage of total kcal comes from fat? (round to the nearest whole number)

Answers

Percentage of total kcal ( total calories ) comes from fat is 66%

To determine the percentage of total calories that come from fat in a cheeseburger, we first need to calculate the number of calories from fat. Fat has 9 calories per gram, so 25 grams of fat would provide 25 x 9 = 225 calories.

Next, we divide the number of calories from fat by the total number of calories in the cheeseburger and multiply by 100 to find the percentage:

(225 / 340) * 100% = 66.18%

Rounding to the nearest whole number, we can say that 66% of the total calories in a cheeseburger come from fat.

a solution is made by mixing of acetone and of methanol . calculate the mole fraction of acetone in this solution. round your answer to significant digits.

Answers

The mole fraction of acetone in this solution is 0.31 to 2 significant digits. The mole fraction of a solute in a solution can be calculated as the number of moles of the solute divided by the total number of moles of both solute and solvent in the solution.

First, we need to calculate the number of moles of acetone and methanol:

moles of acetone = 90 g / (58.08 g/mol) = 1.54 mol

moles of methanol = 108 g / (32.04 g/mol) = 3.36 mol

Next, we add up the moles of both solute and solvent:

total moles = 1.54 mol + 3.36 mol = 4.90 mol

Finally, we can calculate the mole fraction of acetone as follows:

mole fraction of acetone = (1.54 mol of acetone) / (4.90 mol) = 0.31

So the mole fraction of acetone in this solution is 0.31 to 2 significant digits.

A homogenous mix comprising two or more parts with particles less than 1 nm is referred to as a solution. Solutions can take various forms, including soda water, salt and sugar solutions, and others.

Let's name the initial solution's percentage "C1."

The intensity of the reaction solution is when 2.00 ml of initial sample is moved to a 100.00 ml of volumetric flask to 100.00 with water.

(2.00 ml) / (100.00 ml + 2.00 ml) * C1 =

When 5.00 ml of this solution is then diluted to 100.00 ml, the concentration of the final solution is

(5.00 ml) / (100.00 ml + 5.00 ml) * (0.0195 * C1) =

0.0476 * 0.0195 * C1 =

0.000158 M.

So, we can find the original concentration, C1, by rearranging the above equation:

C1 = (0.000158 M) / (0.0476 * 0.0195)

the ph of the stomach can influence the ionization of drugs such as aspirin (aka acetylsalicylic acid or hasp). given that at equilibrium the ph of a 0.1 m aspirin is 2.24, what is the pka of aspirin?

Answers

The ph of the stomach can influence the ionization of drugs such as aspirin (aka acetylsalicylic acid or hasp). given that at equilibrium the ph of a 0.1 m aspirin is 2.24. So the pKa of aspirin is approximately +∞.

The pKa of aspirin can be calculated from the pH of a 0.1 M solution of aspirin at equilibrium using the following equation:

pKa = pH + log([A-]/[HA])

where,

[A-] and [HA] = the concentrations of the aspirin ionized (A-) and non-ionized (HA) forms, respectively.

At a pH of 2.24, the concentration of the ionized form of aspirin is much higher than that of the non-ionized form,

so we can assume that

[A-] ≈ 0.1 M

[HA] ≈ 0.

Substituting these values into the equation, we get:

pKa = 2.24 + log(0.1/0) = 2.24 + log(infinity) = 2.24 + +∞ = +∞

So the pKa of aspirin is approximately +∞.

Answers

we can use this principle law of conservation of mass: 25 g + 26 g = 17 g + x g, where x represents the mass of d produced. Solving for x, we find that x = 34 g, so 34 g of d are produced.

The law of conservation of mass states that mass is conserved in a chemical reaction, meaning that the total mass of reactants must equal the total mass of products.

In a chemical reaction, the law of conservation of mass states that the total mass of reactants must equal the total mass of products. Using this principle, we can solve for the unknown mass of a product in a reaction. In this hypothetical reaction, 25 g of a and 26 g of b react to produce 17 g of c and some amount of d. We can write an equation to represent the relationship between the masses of reactants and products: 25 g + 26 g = 17 g + x g, where x represents the mass of d produced. To find the value of x, we can solve the equation: 25 g + 26 g = 17 g + x g, so x = 25 g + 26 g - 17 g = 34 g. Therefore, 34 g of d are produced in this reaction.

an electron in a 3s orbital penetrates into the region occupied by core electrons more than electrons in a 3p orbital?

Answers

Answer:

Explanation:

The penetration of an electron into the region occupied by core electrons is determined by the electron configuration and the energy of the orbital.

Electrons in 3s orbitals are lower in energy than electrons in 3p orbitals and are therefore closer to the nucleus. As a result, electrons in 3s orbitals penetrate more deeply into the region occupied by core electrons. This means that electrons in 3s orbitals are more strongly attracted to the positively charged nucleus, and have a higher probability of being found closer to the nucleus compared to electrons in 3p orbitals.

In contrast, electrons in 3p orbitals are higher in energy and have a more diffuse distribution, meaning they are less likely to penetrate into the region occupied by core electrons and are more likely to be found farther away from the nucleus.

In conclusion, electrons in a 3s orbital penetrate more deeply into the region occupied by core electrons than electrons in a 3p orbital.
