Use the balanced chemical equation to work the following problem. 2c4h10 + 13o2 → 8co2 + 10h2o how many grams of co2 (molar mass = 44.01 g/mol) would be formed from the total reaction of 5.00 g of c4h10 (molar mass = 58.1 g/mol)? 15.1 g 0.947 g 0.114 g 26.4 g

Dumbledore decides to gives a surprise demonstration. he starts with a hydrate of na2co3 which has a mass of 4.31 g before heating. after he heats it he finds the mass of the anhydrous compound is found to be 3.22 g. he asks everyone in class to determine the integer x in the hydrate: na2co3·xh2o; you should do this also. round your answer to the nearest integ
