1. Based on THE REACTION BELOW – Using the amount of fuel you calculated in grams to get you from school and back, how many grams of Carbon Dioxide is produced if there is an unlimited supply of oxygen? This reaction is assuming that your car burns fuel in a complete combustion reaction… which it probably doesn’t.. but do it anyways…
2 C8H18 (g) + 25 O2 (g) à 16 CO2 (g) + 18 H2O (g)
2. Based on THE REACTION BELOW – Generally cars burn fuel with an unlimited supply of oxygen gas in the atmosphere. Assuming for some silly reason there was only 10.00 grams of oxygen available. Your car would stop working when the oxygen runs out, but that would be the least of your worries! Based on the amount of fuel you calculated at the start, and the 10.00g of oxygen, how many grams of water would be produced?
2 C8H18 (g) + 17 O2 (g) à 16 CO (g) + 18 H2O (g)
3. Based off what happened above, how much gas in grams would be NOT used due to the lack of oxygen (solve for excess C8H18 in grams)
A laboratory conducts a study to examine the effect of difference levels of nitrogen on the yield of lettuce plants. Use the data shown here to fit a linear regression model. Test for possible lack of fit of the model. Use a = 0.05.
250 ml of solution were prepared by dissolving of 2.3 g of the non-electrolyte in water. Calculate the molar mass of solute if the osmotic pressure of solution at 27oC is equal to 249 Kpa.
1. In the reaction Mg(OH)2 + 2HCl → MgCl2 + 2H2 O, you were given 15
grams of Mg(OH)2 and 25 grams of HCl. Which of the two reactants is the
limiting reagent? How much MgCl2 will be produced in the reaction? (Mg(OH)2
= 58.32 g/mol, HCl = 36.46 g/mol, MgCl2 = 95.32 g/mol)
. Calculate the percent by mass of sodium hypochorite in her disinfectant solution. (
5Tbsp. of NaClO (sodium hypochlorite) and 3.8 liters of H2O (water). In units of grams
for both of the solute and solvent.
Based on the below reaction, how many moles of CO2 will be produced if 14.45 moles of O2 react completely with excess C3H8? Round your answer to 2 places after the decimal. You do not need to include units.
C3H8 + 5O2 --> 3CO2 + 4H2O
Based on the below reaction, how many moles of NH3 will be produced, if 28.23 moles of H2 react completely with excess N2? Round your answer to 2 places after the decimal.
N2 + 3H2 --> 2NH3
Based on the below reaction, how many moles of N2 are need to react completely with 10.42 moles of H2? Round your answer to 2 places after the decimal.
N2 + 3H2 --> 2NH3
1. In a 35.0 L automobile air bag, a sample of gaseous nitrogen has a pressure of 745 mm Hg. If this
sample is transferred to a 25.0 L bag at the same temperature, what is the final pressure of the gas?
A nitrogen sample has a volume of 6 litres at 35 degrees celsius and a pressure of 0,974.What volume will it occupy at STP
