Fresh orange juice contains approximately 10 wt% solids (sugar, citric acid, etc.) and the remainder water, while frozen concentrate contains approximately 42 wt% solids and 58 wt% water. the frozen concentrate is obtained by evaporating water from the fresh juice to produce a mixture that is approximately 65 wt% solids. however, so that the flavor of the concentrate will closely approximate that of fresh juice, the concentrate from the evaporator is blended with fresh orange juice to produce a final concentrate that is approximately 42 wt% solids. assume a basis of 100 kg fresh juice fed to the process (a) draw and label a flowchart of this process, neglecting vaporization of everything in the juice but water. then perform a degree of freedom analysis for the overall system, the evaporator, the mixing point and the splitting point. (20 points) (b) calculate the amount of product (429% concentrate) produced and the fraction of the feed that bypasses the evaporator. (40 points) (c) most of the volatile ingredients that provide the taste of the concentrate are contained in the fresh juice that bypasses the evaporator. you could get more of these ingredients in the final product by evaporating to 90% solids instead of 65%; you could then bypass a greater fraction of the fresh juice and thereby obtain an even better tasting product suggest possible drawbacks to this proposal.

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
