Chlorine gas reacts with fluorine gas to produce chlorine trifluoride.  The unbalanced reaction is Cl2 (g)  +  F2 (g)  --->  ClF3 (g) Balance the reaction and using atomic weight of Cl = 35.45 and F = 19.00, Determine how much ClF3 (in grams) will be produced by reacting 50.0 g of Cl2 with 60.0 g of F2. Write you answer to 3 digits - for example 15.6.  Do not include the word grams.

5. An organic compound containing only C, H, and possibly O was subjected to combustion analysis. A sample weighing 0.7585 g yielded 1.295 g CO₂ and 0.464 g H₂O. What is the empirical formula of the compound?

Cryolite, Na3AlF6(s),Na3⁢AlF6⁢(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. Balance the equation for the synthesis of cryolite. equation: Al2O3(s)+NaOH(l)+HF(g)⟶Na3AlF6+H2O(g)Al2⁢O3⁡(s)+NaOH(l)+HF(g)⟶Na3⁢AlF6+H2O(g)   If 15.2 kg of Al2O3(s),15.2 kg of Al2⁢O3⁡(s), 56.4 kg of NaOH(l),56.4 kg of NaOH(l), and 56.4 kg of HF(g)56.4 kg of HF(g) react completely, how many kilograms of cryolite will be produced?   mass of cryolite produced:     Which reactants will be in excess? a. Al2O3Al2⁢O3 b. NaOHNaOH c. HF What is the total mass of the excess reactants left over after the reaction is complete?   total mass of excess reactants:

Consider the following chemical reaction: CaO(s) + H2O(l) ----------> Ca(OH)2 (aq) if 1.00 g calcium oxide is mixed with 2.00 g water, calculate grams of the product. CaO = 56.08 g/mole,  H2O = 18.02 g/mole,  Ca(OH)2 = 74.10 g/ mole
