The reaction of 4.8 g sulfur and 5.4 g aluminum yields 4.5 g
Al2S3 in the reaction below:
35 + 2A1 - Al2S3
Determine the percent yield of Al2S3. (Molar mass of S = 32
g/mol, molar mass of Al = 27 g/mol)
Enter the answer

Match the acid base pairs by arranging the acid name with the conjugate base formula. hydrogen carbonate hydrogen phosphate carbonic acid read water sulfuric acid phosphoric acid a. co32- b. hso4- c. hco3- d. po43- e. h2po4- f. oh-

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
