Question 36 options: A chemistry student at GGC synthesized a new sulfonamide (S7) drug to help treat malaria. Using a spectrophotometer the student observed that S7 converts to a colorless molecule in the presence of malaria parasite called Plasmodium falciparum. To study the rate of reaction, the student recorded the absorbance/amount of S7 at a wavelength of 570 nm. The results are summarized in the table below: Time (s) Absorbance/Amount of S7 0 0.80 5 0.63 10 0.50 15 0.40 20 0.32 25 0.25 30 0.20 Determine the half-life of S7. Include units in your answer.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
