My freezer broke,so I had to empty $500 of ruined food from the 390 liter freezer Now that my freezer is empty, room temperature,and waiting for the haul-away,if I were to fill it with 100% nitrogen gas instead of food, how many moles of nitrogen would fill a 390 liter freezer at STP?

Please draw missing products. I need drawings!! Thank you ( please step by step answer please )

A physician request 2.5 L of a35% solution the pharmacy has 12.5% and 45% solution in stock what volume of the 45% and 12.5% solution are needed to fill this order?

A person (70kg) eating locally caught fish from water contaminated with 100ppb TCE and 100ppb aniline. The bioconcentration value for TCE and aniline in fish is the same at 1.06mg TCE (or aniline) per kg fish, respectively. Fish is only exposed to these contaminants in its environment. About 54g of fish is consumed in 350days/yr for 30years. Assume bioavailability value of 1. The potency factor for TCE is 1.1 × 10$# kg.day/mg and reference dose is 1.00 × 10$% mg/kg.day. Whereas the potency factor for aniline is 5.7 × 10$* kg.day/mg and reference dose (based on drinking water) is 1.60 × 10$& µg/L. Unlike aniline, TCE is not a carcinogenic compound. There are 70yrs in a lifetime and 365day/yr. a) Using chronic daily intake calculation, determine the non-cancer risk (number of people in one million) for the above case. b) Calculate the cancer risk (number of people in million) for the above case.

An average man requires 2.00 mg of riboflavin (Vit. B₂) per day. How many pounds of cheese would a man have to eat per day, if this were his only source or riboflavin and if the cheese contained 5.5 microgram Riboflavin per gram?

The hydrolysis of a substrate, S, by an enzyme has been studied in the lab. The following initial rates, vo, were recorded at different concentrations. [S] (M) Vo (M/min) 2.10-10-4 1.20.10-6 4.20-10-4 3.10.10-6 9.30-10-4 6.30-10-6 1.42-10-3 9.10-10-6 A. Determine the rate constants for degradation of the substrate B. What is the rate of reaction at [S] = 1.1.104 M? C. Explain, why enzymes can make reactions go faster? Does enzymes also catalyse the reverse reaction from product to substrate?
