A. Anna's chemistry class is going to be experimenting with AgNO, today, which can stain hands and clothes. Anna is concerned about her jewelry, so as she gets ready for school, she removes her gold (Au) ring and replaces it with a cheaper nickel (Ni) ring. Is this a good idea? Explain your answer. (4 points) i. Use the activity series of metals to determine what would happen if AgNO, spilled on Anna's nickel (Ni) ring. Explain your answer. (2 points)

ii. Using the activity series of metals, explain what would happen if AgNO, spilled on her gold (Au) ring. (2 points)​

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?

Acompound contains c, h, and o atoms. when 1.130 g of the compound is burned in oxygen, 1.064 g co2 and 0.3631 g h2o are produced. what is the empirical formula of this compound?

Arecipe calls for 1.2 cups of oil. how many liters of oil is this?
