As you answer the following questions, write explanations for why your current answer is correct

An aqueous solution of sodium bisulfate (NaHSO4) is acidic. Sodium bisulfate dissociates in water to form the bisulfate ion (HSO4-) and the sodium ion (Na+). This reaction can be represented by the following chemical equation:

NaHSO4 (s) → Na+ (aq) + HSO4- (aq)

The bisulfate ion is a weak acid, and it dissociates further in water to form the sulfate ion ([tex]SO4^{2-}[/tex]) and the hydrogen ion (H+):

HSO4- (aq) → H+ (aq) + SO42- (aq)

This additional dissociation of HSO4- increases the concentration of H+ ions in the solution, making the solution acidic. The presence of H+ ions in the solution means that the solution has a pH of less than 7, which is the definition of an acidic solution.

What is an aqueous solution?

An aqueous solution is a sort of mixture in which one or more solutes have been dissolved in water as the solvent. Any kind of material, including salts, acids, bases, and sugars, can serve as solutes. The word "aqueous" describes a solution's water content. These kinds of solutions are prevalent in biology and chemistry and are essential to numerous industrial and natural processes.

An aqueous solution is one in which water serves as the solvent. In chemical equations, it is often represented by adding to the appropriate chemical formula. For instance, Na⁺ + Cl⁻ might be used to depict a solution of table salt, or sodium chloride, in water.

Water, which makes up around 70% of the mass of the human body and is necessary for life, serves as the solvent in aqueous solutions.

The reaction will begin to favor products at a temperature of 38.7 K in this experiment.

ΔG. ΔG = ΔH – TΔS, where ΔH is the change in enthalpy, T is temperature, and ΔS is the change in entropy.

For this particular reaction, the change in enthalpy is 10.37 kJ/mol and the change in entropy is 268 J/mol K. Therefore, the Gibbs free energy is -10.14 kJ/mol.

This means that the reaction will begin to favor products when the temperature is high enough to offset the negative change in Gibbs's free energy.

To calculate the temperature at which the reaction will favor products, we use the equation

ΔG = 0 = ΔH – TΔS.

Solving for T, we get

T = ΔH/ΔS = 10.37 kJ/mol/268 J/mol K = 38.7 K.

The amount of substance removed from the sassafras tree's bark was 40.5 mg, while the amount of CO2 produced was 110.0 mg.

obtained water mass = 22.5g

Calculation of C, H, and O percentages

12 g of Carbon is present in 44 g of CO2. Similarly 2 g of H is present in 18 g of water. Using this we calculate

Percentage of C = 12/44 x Mass of CO2 / Total mass of Compound X 100 = 12/44 x 110.0/40.5 x 100 = 74.07

Percentage of H =2/18 x Mass of H2O / Mass of compound = 2/18 x 22.5/40.5 x 100 = 6.17

Percentage of O =100-6.17-74.07=19.76    ( As compound contains only C H and O)

The percent yield for a reaction can be calculated as follows:

% yield = (actual yield / theoretical yield) x 100

First, we need to find the theoretical yield of FeCl2. To do this, we need to determine the number of moles of Fe that reacted with the HCl. The balanced chemical equation for this reaction is:

Fe + 2HCl → FeCl2 + H2

From the given information, we know that 3.37 g of HCl was used in the reaction. We can use the molar mass of HCl (36.46 g/mol) to convert this mass to moles:

3.37 g HCl / 36.46 g/mol = 0.0927 moles HCl

Since two moles of HCl react with one mole of Fe, the number of moles of Fe used in the reaction is half of the number of moles of HCl:

0.0927 moles HCl / 2 = 0.04635 moles Fe

Next, we can use the molar mass of FeCl2 (126.90 g/mol) to determine the theoretical yield of FeCl2:

0.04635 moles FeCl2 x 126.90 g/mol = 5.89 g FeCl2

Finally, we can calculate the percent yield:

% yield = (4.20 g FeCl2 / 5.89 g FeCl2) x 100 = 71.56%

The total pressure of a mixture of gases is equal to the sum of the partial pressures of each gas. The partial pressure of a gas is proportional to the number of moles of that gas present in the mixture. In this case, we can use the ideal gas law, PV = nRT, to find the partial pressures.

First, we need to find the molar gas constant R:

R = 8.31 J/mol * K

Next, we need to find the temperature in Kelvin:

T = 200 K

Now, we can calculate the partial pressure of each gas in the mixture:

P N2 = (122 moles . R . T) / (75.0 L) = 122 . 8.31 . 200 / 75.0 = 735.72 kilopascals.

P C3H8 = (137 moles . R . T) / (75.0 L) = 137 . 831 . 200 / 75.0 = 807.69 kilopascals.

P CO2 = (212 moles . R . T) / (75.0 L) = 212 . 831 . 200 / 75.0 = 1307.48 kilopascals.

Finally, we can find the total pressure of the mixture:

Ptotal = P N2 + P C3H8 + P CO2

Ptotal = 735.72  + 807.69 + 1307.48

Ptotal = 2850.89 kilopascals

So, the total pressure of the gas is 2850.89 kilopascals, and the partial pressure of CO2 is P CO2 = 1307.48 kilopascals.

Both redistribution to acceleration in all other types of motion. If car A is traveling 20 mph and is hit from behind by Car B (approximately the same mass) traveling 60 mph, Car A will spontaneously combust from impact.

Therefore, the correct option is option D.

Answer:

Car A will accelerate in the direction of motion.

Explanation:

If a car driving slowly was hit from behind by a car going 3 times its speed, car A will be pushed forward in result.

The relative error is calculated by taking the difference between the actual titration volume and the expected titration volume, dividing by the expected titration volume.

Titration is a laboratory process used to measure the precise concentration of a solution. It is a quantitative analytical technique that involves the controlled addition of a reagent (titrant) to a sample solution until a specific endpoint is reached. This endpoint is identified by a chemical reaction that signals that the titrant has been completely consumed. By measuring the amount of titrant added and the concentration of the sample solution, the concentration of the sample can be accurately determined.

And then multiplying by 100. In this case, the actual titration volume is 60.00 ml and the expected titration volume is 0.02 ml, so the relative error is Relative Error = (60.00 - 0.02) / 0.02 * 100 = 2,999,900% .This indicates that the titrant volume was too large by a factor of 2,999,900%. This large of a relative error indicates that something went wrong in the titration process and the titrant was added too quickly or in too large of an amount.

The pH of the solution when 50.0 mL of a 0.10 M solution of fully protonated glycine (glycine hydrochloride) is titrated with 50.0 mL of 0.10 M NaOH is approximately 8.72.

This is because NaOH is a strong base and will completely neutralize the glycine hydrochloride. To calculate the pH, we can use the equation pH = -log[H3O+], where [H3O+] is the concentration of the hydronium ions in the solution. In this case, the concentration of hydronium ions is equal to the concentration of the NaOH, which is 0.10 M. Taking the negative log of this gives us a pH of 8.72.
