You can ' t acid clean your aluminum auto parts for the same reasons : 2 Al + 6 HCl → 2 AlCl3 + 3H2 . If you were able to dissolve 10.0 mol of Al , how many many moles of hydrogen gas could you make ? NOTE : All numbers located immediately after elemental symbols should be considered subscripts
9 . Sodium and chlorine are very dangerous by themselves . However , when we combine them together in a chemical reaction , we eat it--it ' s table salt : 2Na + Cl2 → 2NaCl . If I want to make 100.0 g of my own salt ( because I can and that ' s how I roll ), how much elemental chlorine would I need ? NOTE : All numbers located immediately after elemental symbols should be considered subscripts
10 . Sodium and chlorine are very dangerous by themselves . However , when we combine them together in a chemical reaction , we eat it--it ' s table salt : 2Na + Cl2 → 2NaCl . If I want to make 50.0 g of my own salt ( because I can and that ' s how I roll ), how much elemental sodium would I need ? NOTE : All numbers located immediately after elemental symbols should be considered subscripts
11 . Alkali metals are extremely reactive with water . Suppose I give you a 55.50 g chunk of cesium and you throw it into a lake . When it reacts with water to form cesium hydroxide and hydrogen gas , how much hydrogen in grams is theoretically produced ? Write a balanced equation for the reaction and show all work clearly and in detail to receive credit . All numbers seen immediately following the elemental symbols are intended to be subscripts
12 . Consider the solubility rules and identify all of the spectator ions when the following chemicals react : A ) lead ( II ) nitrate and ammonium chloride B ) Barium bromide and potassium carbonate . You must show all work ( equations ) clearly and in detail to receive credit
