Question

PROBLEMS Work the following problems systematically by writing the Units Scheme and the Conversion scheme showing that the dimensional analysis confirms that the conversion scheme is set up correctly and then inserting number into the Conversion Scheme Full credit will only be given for showing the steps. Some question requires balancing the equations. A periodic table is given on the last page for calculating molecular and atomic masse. Report e rs, with units, to the correct number of significant figures. 1. The combustion reaction of propane (CH) is its reaction with oxygen (Os), producing Co, and How many moles of Co, are theoretically produced in the combustion of 6.8 moles of propane? a) Write the balanced reaction equation C H + 700 Mg + OaCO+H2O b) Write the Units Scheme Write the Conversion Scheme with units only and perform dimensional analysis to show it is set up correctly d) Rewrite the Conversion Scheme inserting numbers and calculate the answer For the balanced chemical reaction equation below, how many grams of sodium nitrate will theoretically be produced from 3.46 moles of chromium (II) nitrate? 2 Cr(NO3h + 3 Nas → Crass + 6 NaNO, -) Write the Units Scheme Write the Conversion Scheme with units only and perform dimensional analysis to show it is set up correctly write the Conversion Scheme inserting numbers and calculate the answer

Answer 1

1 (a) CaMg +502 3 CO₂ + 4H₂O I mole of propane reacts with 5 moles of oxygen gas to produce 3 moles of co₂ (carbon dioxide) and 4 moles of H₂O (water). 1 mole of propane produces 3 moles of CO2 duce inol mo рраме I mole of propane 'x' moles of propane will produce (3 moles of cox - a moves on.com x 582) meies of propane x 'x' moles of propane 3 moles of 202 I mole of propane (d) Hese we are given with 6.8 moles of propane 6.8 moles of propane moles of co2 produces = 3 moles of CO2 X Imol of propane 20.4 moles of CO2 Kindly submit seperately!
