Gay-Lussac's Law Directions: Show all of your work and cancellation of units to save points! (note \( 1 \mathrm{~atm}=760 \) Torr) 1.) If the pressure of a balloon is 870 Torr at room temperature \( \left(20^{\circ} \mathrm{C}\right) \), what is the temperature of the room if the pressure is changed to \( 10 \mathrm{~atm} \) ? \( \frac{F}{F} \) 2.) If the pressure of a balloon is \( 1 \mathrm{~atm} \) at room temperature \( \left(20^{\circ} \mathrm{C}\right) \), what is the pressure of the balloon if the temperature rises to \( 60^{\circ} \mathrm{C} \) ? 3.) If the pressure of a balloon is 780 Torr at room temperature \( \left(20^{\circ} \mathrm{C}\right) \), what is the pressure of the balloon if the temperature rises to \( 40^{\circ} \mathrm{C} \) ?

If Hydrogen Peroxide can be decomposed into Water and Oxygen gas, how many grams of water is formed if one \( 32 \mathrm{fl} \mathrm{oz} \) bottle has 8 moles of Hydrogen Peroxide (yes I did the math)? \( 2 \mathrm{H}_{2} \mathrm{O}_{2}(\mathrm{l}) \rightarrow 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{~g}) \) \( 11 \ln 0) \) How many moles of Nitric Oxide are formed in the following reaction if you start with 42 grams of Ammonia in a room filled with Oxygen Gas? (the molar mass of Ammonia is \( 17.04 \mathrm{grams} / \mathrm{mol} \) ) \[ 2 \mathrm{NH}_{3}(\mathrm{~g})+3 \mathrm{O}_{2}(\mathrm{~g}) \rightarrow 3 \mathrm{H}_{2} \mathrm{O}(\mathrm{l})+\mathrm{N}_{2} \mathrm{O}_{3}(\mathrm{~g}) \] (4.) How many grams of Chloroform \( \left(\mathrm{CHCl}_{3}\right) \) are formed if you have 30 grams of \( \mathrm{CH}_{2} \mathrm{Cl}_{2} \) and a room full of Chlorine gas? 2) \( \mathrm{CH}_{2} \mathrm{Cl}_{2}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \rightarrow \mathrm{CHCl}_{3}(\mathrm{l})+\mathrm{HCl} \) (g)

Given the equation: \( 3 \mathrm{Fe}(\mathrm{s})+4 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightarrow \mathrm{Fe}_{3} \mathrm{O}_{4}(\mathrm{~g})+4 \mathrm{H}_{2}(\mathrm{~g}) \) When 8 moles \( \mathrm{H}_{2} \mathrm{O} \) is mixed with 4 moles \( \mathrm{Fe} \), which is the limiting reagent? \( 4 \mathrm{H}_{2} \) 2.) Given the equation: \( \mathrm{SiO}_{2}(\mathrm{~s})+4 \mathrm{HF}(\mathrm{g}) \rightarrow \mathrm{SiF}_{4}(\mathrm{~g})+2 \mathrm{H}_{2} \mathrm{O} \) (l) (The Molar Mass of \( \mathrm{SiO}_{2} \) is \( 60.09 \mathrm{grams} / \mathrm{mol} \) ) If we start with 6 moles of \( \mathrm{HF}^{\prime} \) and 45 grams of \( \mathrm{SiO}_{2} \) which is the limiting reagent?
