Extracted text: Two chemicals A and B are combined to form a chemical C. The rate, or velocity, of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially, there are 100 grams of A and 50 grams of 8, and for each gram of B, 2 grams of A is used. It is observed that 25 grams of Cis formed in 9 minutes. How much is formed in 36 minutes? (Round your answer to one decimal place.) grams What is the limiting amount of C after a long time? grams How much of chemicals A and 8 remains after a long time? A grams grams At what time is chemical C half-formed? min
