- The human body converts sugar into carbon dioxide and water at body temperature (98.6F, or 37.0C). Why are much higher temperatures required for the same conversion in the laboratory?arrow_forward1. Why is chemical potential analogous to temperature and pressure?arrow_forward1 The accepted density of water at room temperature is approximately 1.0 g/mL. Melody and Margaret were told by their professor to measure 7.0 mL of water, which should theoretically weigh 7.0 grams. They first measured the volume of water in a graduated cylinder to be 7.0 mL and then the students weighed the water and they obtained a mass of 6.85 grams. First, calculate the density of their sample of water and then calculate their percent error for density. 2. A science teacher tells her class that their final project requires the students to measure a specific variable and determine the velocity of a car with no more than 2.5% error. Jennifer and Johnny work hard and decide the velocity of the car is 34.87 meters/second. The teacher informs them that the actual velocity is 34.15 meters/second.

Explain.arrow_forwardNanotechnology, 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 23 nanometers. A) What is the volume of one nanocontainer? (Ignore the thickness of the nanocontainer's wall.) B)Suppose that each nanocontainer could contain pure oxygen pressurized to a density of 85 g/Lg/L . How many grams of oxygen could be contained by each nanocontainer?…arrow_forward
