Some theories of aging suggest that free radicals cause certain diseases and perhaps aging in general. as you know from lewis theory, such molecules are not chemically stable and will quickly react with other molecules. free radicals may attack molecules within the cell, such as dna, changing them and causing cancer or other diseases. free radicals may also attack molecules on the surfaces of cells, making them appear foreign to the body's immune system. the immune system then attacks the cells and destroys them, weakening the body. draw lewis structures for each of the following free radicals implicated in this theory of aging. a. o–b. o2–c. ohd. ch3oo (unpaired electron on terminaloxygen)

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night. when he took it out, its new volume was 322 milliliters, but its pressure was the same. if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is kelvins.
