Sodium hypochlorite is the active ingredient in most household bleach products. One method of preparing this compound is as follows: Cl2(g) + 2N2OH(aq) → NaOCI (aq) + NaCl(aq) + H2O(1) In a certain experiment, 50.0 g chlorine was reacted with 50.0 g sodium hydroxide to yield 37.8 g sodium hypochlorite. (a) Calculate the theoretical yield (b) Calculate the percent yield.

Barium hydride reacts with water to produce barium hydroxide and hydrogen gas. BaH₂ (s) + 2 H₂O(1)→ Ba(OH)2 (aq) + H₂(g) If 6.389 g BaH2 is combined with 64.000 g H₂O, the reaction proceeds until all the BaH₂ is consumed. The hydrogen gas escapes to the environment, and the final weight of the flask is 70.204 g. The remaining water is evaporated, leaving 7.856 g Ba(OH)2.
