Part 1. A chemist reacted 12.0 liters of F222F22 gas with NaCl in the laboratory to form Cl gas and NaF. Use the ideal gas law equation to determine the mass of NaCl that reacted with F at 280. K and 1.50 atm.
+ 2NaCl → Cl + 2NaF
Part 2. Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.

Which fact represents evidence for the big bang theory?

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
