please help woth calculations with #3,4,5. thank you! Data: Original mass of candle: 30.81 Mass after 5 minutes of combustion: 369 Mass of candle lost to combustion: 0:16 Calculations: A typical wax used for making candles is paraffin wax, which has the molecular formula CisHs2. With this information, answer the following questions using the data you recorded for your candle. Show your work! 1. What is the molar mass of candle wax, CzHsz? 25(12.011) +52(1.008)= 352.69 g/mol 2. How many...

2. If we mix sodium bicarbonate with acid, carbon dioxide will be produced. If one mole of a gas occupies about 22 liters at standard temperature and pressure, how many milliliters of carbon dioxide would be produced from the reaction given at the top of page 143 (Williamson, 6th Ed.), if 50 mg of benzoic acid was converted to sodium benzoate?
Assume the volume occupied by one mole of gas is 22.4 L, and that all the ammonia gas produced from the reactions bubbled out from solution. Calculate the volume of gas produced from the reaction of 18 mL of 9 M NaOH with 7 g of NH4Cl (and 20 mL of deionized water) if the reaction proceeds to completion.
Consider the following reaction: 4NH3(g) + 7O2(g) à 4 NO2(g) + 6H2O (l) Is it a balanced or unbalance equation? How many liters of nitrogen dioxide gas is produced from 527 g of gaseous ammonia? Hint: At standard temperature & pressure, 1 mole gas occupies 22.4 Liters
. You have 1 mole of carbon dioxide at 400 K. You determine the volume of the gas at 30 atm is 1.03 L. Is carbon dioxide behaving as an ideal gas? If not, determine the second virial coefficient

I do not understand #5 1) Write the balanced chemical equation for the combustion of hexane, including physical states. Combustion reactions occur during burning, releasing heat and generally accompanied by light. Because of the heat, water will be produced as a vapor. 2 C6 H14 (g) + 19 02cg) 12 CO2 (g) + 14 H2O (9) Use the balanced chemical equation above and stoichiometry to solve the following problems. 2) Calculate the maximum number of moles of carbon dioxide that...
