Answer the following questions/problems showing appropriate work (in the space provided or on back of paper.<br> <br> 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.<br> <br> <br> 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.<br> <br> <br> 3) Hydrogen gas and nitrogen gas react to form ammonia (N<sub>1</sub>H<sub>3</sub>) gas. How many grams of nitrogen gas (at 62°C and 83.2l <nowiki>KP</nowiki>a) is needed to form 91.3g of ammonia gas?<br> <br> <br> 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 <b>of carbon dioxide gas</b> (at 571mmHg and 83°C)?<br> <br> <br> 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)?<br> <br> <br> <br> Answers:<br> <br> 1) 4.44g H<sub>2</sub>O<sub>1</sub><br> 2) 4.86L H<sub>2</sub><br> 3) 75.2g N<sub>2</sub> (suppose to ask for volume,89.9L or 90.0L N<sub>2</sub>) <br> 4) 10.7 L CO<sub>2</sub><br> 5) 0.129L or 129mL<br> <br> <br>
