Please show and explain the work to figure out these questions 1. you react 3.50 g of solid sodium metal with water to produce hurdogen gas and sodium hydroxide. if at the end of the reaction there is 6.8 l of solution, what is the concentration of sodium hydroxide? Answer: 0.022 M NaOH 2. an excess of aqueous calcium chloride is reacted with 350 ml of .650 M aqueous sodium carbonate. if 10g of a solid is produced, what is the percent yield Answer: 43.8%
