Glucose, Sucrose, Fructose, and Amylose. Which carbohydrate listed can be hydrolyzed, and why?

Perhaps you recall that when table salt, NaCl, is added to water, the freezing point of water is lowered. Consider a system composed of a mixture of 2.5kg of ice and 50g of liquid water and a small, separate container of finely powdered salt. This physical system is contained in a fully insulated container that prevents all thermal interactions with the environment. Both the salt and the ice-water mixture are initially at the freezing point of water, 0 °C. The salt is then added to the ice-water mixture, and the system of ice-water and salt is allowed to come to thermal equilibrium. The final equilibrium temperature is less than 0 °C.

Use the Energy-Interaction Model Preview the document to predict if there will be a greater or lesser amount of ice in the final equilibrium state than in the initial state before the salt was added. Your explanation should include a complete Energy-System Diagram. [The simplest way to model this physical system is with one thermal energy system for everything and one bond energy system, i.e., in terms of the model, it is not useful to distinguish between the various chemical components in order to answer this particular question.]

A solution is made by combining 15.0 mL of 17.0 M acetic acid with 5.50 g of sodium acetate and diluting to a total volume of 1.50 L.

Molar Mass by Freezing Point Depression I am doing a latenite lab on Molar Mass by Freezing Point Depression. I have asked this question on Course Hero and twice on Chegg and the tutors keep giving me different answers. Sample 2 has a van't Hoff factor of 2. It began freezing at -3.6. I added 2 g of the unknown to 10 mL of water. I was given that the Kf for water is 1.86.

Calculate the molar mass of FP sample 2

The vapor pressure of liquid benzene is 17.7 kPa at 30 ºC and 37.7 kPa at 50 ºC. a) Calculate the enthalpy of vaporization of benzene. b) Estimate the vapor pressure at 10 ºC [use your answer from part (a)]. c) Estimate the normal boiling point of benzene (use a vapor pressure of 1 bar and use the result from part (a)]

1. Olive oil has a saponification value of 190 mg KOH per gram. This means that it takes 190 mg of potassium hydroxide to react completely with 1 g of olive oil.

(a) What is the mole ratio for the reaction of a triglyceride with KOH?

(b) Divide 0.190 g of KOH by its molar mass to calculate the number of moles of KOH that will react with 1 g of olive oil.

(c) Use the answers to (a) and (b) to determine the number of moles corresponding to 1 g of olive oil. Divide 1 g by this number of moles to calculate the average molar mass (g/mole) of olive oil.

1) Explain why there are so few metallic materials with one-dimensional bands. Naming and describe the type of distortion responsible for this.

2) Why are the superconducting critical temperatures of conventional superconductors often highest when the material has the apparently contradictory features of having strong bonds but poor orbital overlap between atoms associated with the conduction band?

calculate the mole fraction of a fractional distillation? How do I find the mole fractions of different distillations given only the refractive index, the temperature and which the distillation was acquired, and the makeup on the original solution before distillation?

the lab manual says to use P= (px * mol frac x)+(py * mol frac y)

but i don't know how I can find their partial pressure given that I don't know their mole fractions of the distillation since partial P=mole frac * vapor pressure.

The electro attractive inductive effect of the alkenyl and alkynyl groups has been attributed to the hybridization of unsaturated carbon with respect to that of saturated carbon. Discuss the rational basis of this idea.

Using standard electrode potentials calculate ΔG∘rxn and use its value to estimate the equilibrium constant for each of the reactions at 25 ∘C.

A. Cu2+(aq)+Zn(s)→Cu(s)+Zn2+(aq)

B. Br2(l)+2Cl−(aq)→2Br−(aq)+Cl2(g)

C. MnO2(s)+4H+(aq)+Cu(s)→Mn2+(aq)+2H2O(l)+Cu2+(aq)

Find K. All answers must have one significant figure. Please show all your work and equations used. Thank you!!

Calculate the percent ionization in a 0.1M solution of hydrofluoric acid (Ka=3.53*10^-4)

when the acid constants of tert-butyl alcohol and methanol are determined in the gas phase, tertiary alcohol is found to be a stronger acid. This result is opposite in aqueous medium. Consider the effects of solvation to explain these different results.

Calculate Percent Yield:

Palm oil was used for the creation of soap. The mass of the oil was 2.001 grams. The base used was 3 M of NaOH. After the experiment, the mass of the soap was 1.622 grams. What is the percent yield?

The average molar mass of the palm oil is 847.3 grams per mol. The average molar mass of the soap is 291.7 grams per mol. 3 mL of the base (NaOH) was used.
