Answers

Answer 1

The required partial pressure of neon in mmHg) in the tank is 272 mmHg.

The partial pressure of neon in the tank is 152 mmHg.A mixture of neon, argon, and helium gases are contained in a tank. The total pressure in the tank is 600. mmHg, while the partial pressures of neon and argon are 120 torr and 0.20 atm, respectively.To calculate the partial pressure of neon in mmHg, we need to convert the pressure of argon to mmHg:0.20 atm x 760 mmHg/atm = 152 mmHgNext, add the partial pressures of neon and argon:120 torr + 152 mmHg = 272 mmHg

Therefore, the answer is 272 mmHg, option (b) is correct.

Your friend works in a bookstore where lab books for science are assembled. Each lab book uses 2 covers, 50 sheets of lined paper, 25 sheets of graph paper and 3 staples. Her inventory includes 150 covers, 7500 sheets of lined paper and 3000 sheets of graph paper and 250 staples. What is the “limiting reactant?” How many complete lab books can be made? How much of each of the other reactants remain in excess?

Answers

Answer:

The limiting reactant is the covers.

We are left with 3750 sheets of lined paper, 1125 sheets of graph paper and 25 staples.

Explanation:

the reaction is:

B - book

C - cover

Sl = sheet of lined paper

Sg - sheet of graph paper

St - staple

1B = 2C + 50Sl + 25Sg + 3St

We have covers for 150/2 = 75 books

We have lined paper for 7500/50 = 150 books

We have graph paper for 3000/25 = 120books

We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.

Because we only have covers for 75 books, covers are the limiting reactant.

After making 75 books we are left with:

0 covers

7500 - 75*50 = 3750 sheets of lined paper

3000 - 75*25 = 1125 sheets of graph paper

250 - 75*3 = 25 staples

The limiting reactant should be the covers.

We are left with 3750 sheets of lined paper, 1125 sheets of graph paper, and 25 staples.

Calculation of the limiting reaction:

The reaction should be like:

B - book

C - cover

Sl = sheet of lined paper

Sg - sheet of graph paper

St - staple

Now the equation should be

1B = 2C + 50Sl + 25Sg + 3St

We have covers for 150/2 = 75 books

We have lined paper for 7500/50 = 150 books

We have graph paper for 3000/25 = 120books

We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.

Now the left should be

7500 - 75*50 = 3750 sheets of lined paper

3000 - 75*25 = 1125 sheets of graph paper

250 - 75*3 = 25 staples

C) CH3OH < CH3CH3 < H2C=O
D) H2C=O < CH3OH < CH3CH3

Answers

The correct answer is D) H2C=O < CH3OH < CH3CH3Explanation:Viscosity is the measure of the resistance of a liquid to flow.

It is the ratio of shear stress to shear rate, which is a measure of how fast the fluid is moving between the plates. It can be measured in different units such as poise or centipoise.The viscosity of a liquid is affected by the attractive forces between the molecules, which depend on the type of molecules and their intermolecular forces. The stronger the intermolecular forces, the more viscous the liquid.In this case, CH3OH (methanol), CH3CH3 (ethane), and H2C=O (acetone) are the compounds to be ranked. Methanol is a polar molecule with hydrogen bonding and has a higher viscosity than ethane, which is nonpolar and has weak van der Waals forces. Acetone is a polar molecule with dipole-dipole interactions that are intermediate between methanol and ethane. The order of increasing viscosity is therefore H2C=O < CH3OH < CH3CH3.

A 0.100 M oxalic acid, HO₂CCO₂H, solution is titrated with 0.100 M KOH. Calculate the pH when 25.00 mL of oxalic acid solution is titrated with 35.00 mL of NaOH. Ka1 = 5.4 × 10−2 and Ka2 = 5.42 × 10−5 for oxalic acid is 1.94.

Oxalic acid is a dicarboxylic acid with the chemical formula HO₂CCO₂H, with a pKa1 of 1.25 and a pKa2 of 4.14. A titration is a process in which a solution of known concentration is added to a solution of unknown concentration until the equivalence point is reached.

The goal of a titration is to determine the concentration of the unknown solution. A 0.100 M oxalic acid solution is titrated with 0.100 M KOH. The pH is calculated when 25.00 mL of oxalic acid solution is titrated with 35.00 mL of NaOH. Ka1 = 5.4 × 10−2 and Ka2 = 5.42 × 10−5 for oxalic acid. Here is how to calculate the pH when 25.00 mL of oxalic acid solution is titrated with 35.00 mL of NaOH:

Step 1: Calculate the moles of oxalic acid

moles of oxalic acid = concentration x volume

moles of oxalic acid = 0.100 M x 0.025 L

moles of oxalic acid = 0.0025 mol

Step 2: Calculate the moles of NaOH

moles of NaOH = concentration x volume

moles of NaOH = 0.100 M x 0.035 L

moles of NaOH = 0.0035 mol

Step 3: Determine which species is in excess

0.0025 mol of oxalic acid reacts with 0.0025 mol of KOH

0.0010 mol of oxalic acid reacts with 0.0035 mol of KOH

0.0010 mol of oxalic acid is consumed in the reaction

The excess moles of NaOH = 0.0035 - 0.0010 = 0.0025 mol

Step 4: Calculate the concentration of the remaining OH- ions

Concentration of OH- ions = moles of OH- ions / volume

Concentration of OH- ions = 0.0025 mol / 0.060 L

Concentration of OH- ions = 0.0417 M

Step 5: Calculate the concentration of H+ ions

Ka1 = [H+][C₂O₄₂-]/[HC₂O₄-]

5.4 x 10^-2 = x^2 / (0.100 - x)

Assuming that x is much smaller than 0.100, x = [H+] = 0.115 M

Step 6: Calculate the pH

pH = -log[H+]

pH = -log(0.115)

pH = 1.94

which of the following is true of carbon? select all that are correct. group of answer choices it can form a maximum of four covalent bonds with other elements. it can form a maximum of three covalent bonds with other elements. it is highly electronegative. it can form both polar and nonpolar bonds. it can only form polar molecules.

Answers

Based on the given options, the following statements are true of carbon: It can form a maximum of four covalent bonds with other elements and It can form both polar and nonpolar bonds.

Carbon is an element with atomic number 6, meaning it has six protons in its nucleus. It has four valence electrons, which are the electrons involved in bonding with other atoms.

Carbon's electron configuration allows it to form four covalent bonds by sharing its valence electrons with other atoms. This property is known as tetravalency and is a fundamental characteristic of carbon.

Additionally, carbon can form both polar and nonpolar bonds depending on the atoms it is bonded to and the electronegativity difference between them.

When carbon bonds with atoms of similar electronegativity, such as hydrogen, the bond is nonpolar because the electrons are shared equally. However, if carbon bonds with atoms of higher electronegativity, such as oxygen or nitrogen, the bond becomes polar due to the unequal sharing of electrons.

In summary, carbon can form a maximum of four covalent bonds with other elements due to its tetravalent nature. It is not highly electronegative itself but can form both polar and nonpolar bonds depending on the atoms it is bonded to. Therefore, the correct statements are:

It can form a maximum of four covalent bonds with other elements.

It can form both polar and nonpolar bonds.

Answers

The dissolution of gases in water is exothermic therefore oceans will dissolve less CO2 as their temperatures rise.

What is  effervescence?

The term  effervescence refers to the rise of a gas in a system or simply put, it is the evolution of gas. When an  effervescent tablet is placed in the water under each inverted glass, a gas will rise in each glass.

The air space in the hot glass  is greater than the air space in the cold glass  We can see that the gas has a lower solubility in hot water than in cold water. This is because, solubility of gases is exothermic.

The bottle that is left in the hot sun will have more fizzing because the CO2 does not dissolve owing to the higher temperature.

The rise in ocean temperature means that the oceans will dissolve less CO2 in the future and reduce the CO2 holding capacity of the oceans.

if you mix equal volumes of 1 m hf and 1 m koh, is the resulting solution acidic , basic, or neutral?

Answers

The resulting solution is neutral when equal volumes of 1 M HF and 1 M KOH are mixed.

When equal volumes of a strong acid and a strong base are mixed, the resulting solution is neutral. In this case, 1 M HF (hydrofluoric acid) and 1 M KOH (potassium hydroxide) are both strong acids and bases, respectively.

When the HF and KOH react, they undergo a neutralization reaction:

HF + KOH → KF + H2O

The reaction between a strong acid and a strong base forms a salt (KF in this case) and water. Since KF is a neutral salt and water is neutral, the resulting solution will be neutral.

A transition metal complex has a a maximum absorbance of 610.7 nm. What is the crystal field splitting energy, in units of kJ/mol, for this complex? Express your answer using at least three significant figures.

Answers

The crystal field splitting energy for the transition metal complex with a maximum absorbance of 610.7 nm is approximately 53.8 kJ/mol.

The absorbance maximum at 610.7 nm corresponds to the energy of the absorbed light, which can be calculated using the equation E = hc/λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Rearranging the equation to solve for the crystal field splitting energy (Δ), we get Δ = hc/λ. Plugging in the values, Δ = (6.626 x 10^-34 J·s * 3.00 x 10^8 m/s) / (610.7 x 10^-9 m). The result is approximately 3.23 x 10^-19 J. To convert this to kJ/mol, we need to multiply by Avogadro's number (6.022 x 10^23) and divide by 1000, giving us a crystal field-splitting energy of approximately 53.8 kJ/mol. This value is obtained by calculating the energy of the absorbed light using the equation E = hc/λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. By rearranging the equation and plugging in the values, we can determine the crystal field splitting energy, which represents the energy difference between the d-orbitals in the complex.
