Suppose that when you wake up in the morning, you are very hungry. you go to the refrigerator and remove an egg. on the way to the stove, you drop the egg on the floor and the egg breaks. you get a second egg from the refrigerator, break the egg shell, and drop the egg into the frying pan. you notice that some eggshell pieces have fallen into your egg, so you pick out the eggshell pieces by hand. you stir the egg to make a scrambled egg. you then turn on the stove and cook the egg. when cooked, you eat the egg. which of the italicized items are physical changes and which are chemical changes? tell whether the following are chemical or physical changes. 1- you drop the egg on the floor and the egg breaks 2- pick out the eggshell pieces by hand 3- stir the egg 4-cook the egg 5-eat the egg

Idon't really understand this can you me and show your work.☺☺[ chemistry b] subject [ electron transfer in lonic bonds]grade( 12)

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?
