explain the steps you would follow to make 500mL of a 0.5 mol/ L solution of sodium chloride (NaCl) in the lab.

Three of the primary components of air are carbon dioxide, nitrogen, and oxygen. In a sample containing a mixture of only these gases at exactly one atmosphere pressure, the partial pressures of carbon dioxide and ni- trogen are given as PCO2 = 0.285 torr and PN2 = 629.702 torr. What is the partial pressure of oxygen?

In a particular reaction between copper metal and silver nitrate, 12.7 g Cu produced 38.1 g Ag. What is the percent yield of silver in this reaction?

Metallic silver can be prepared by the reaction of hydrogen gas with silver oxide.



Silver oxide is a very expensive reactant compared to hydrogen gas. If you were to carry out this reaction in the lab in the most cost effective way to produce a high yield, which of the reactants should be used in excess?
