Answer the following questions/problems showing appropriate work (in the space provided or on back of paper.
1) Hydrogen gas and oxygen react to form water (initially as gas). How many grams of water will I produce if I consume 7.1L of oxygen at 347mmHg and 47°C? Please write complete balanced chemical reaction first.
2) What volume (at 21.5psi and 78°C) of hydrogen gas that needs to be added to the oxygen gas from the Question #1 so that each react "runs out" (called Stoichiometric amounts) at the same time.
3) Hydrogen gas and nitrogen gas react to form ammonia (N1H3) gas. How many grams of nitrogen gas (at 62°C and 83.2l KPa) is needed to form 91.3g of ammonia gas?
4) Using the balanced chemical reaction from the Adding Some Bubbles to the Kicked Bestest Sugared Drink, if I react 721mL of a 0.382M sodium bicarbonate solution to excess citric acid, what will be the volume of carbon dioxide gas (at 571mmHg and 83°C)?
5) If I decided to use a 0.712M solution of citric acid to supply the citric acid instead of the solid acid to Question #4, what volume of this solution would I need for Stoichiometric amounts (i.e. so both reactants "run out" at same time)?
Answers:
1) 4.44g H2O1
2) 4.86L H2
3) 75.2g N2 (suppose to ask for volume,89.9L or 90.0L N2)
4) 10.7 L CO2
5) 0.129L or 129mL
