When a chemist collects hydrogen gas over water, she ends up with a mixture of hydrogen and water vapor in her collecting bottle if the pressure in the collecting bottle is 97.1 kilopascals and the vapor pressure of the water is 3 2 kilopascals, what is the partial pressure of the hydrogen?

Identify the limiting reactant when 9.65-g h2so4 reacts with 6.10-g of naoh. the equation is h2s04 + 2naoh = 2h2o + na2so4• what is the theoretical yield of na2so4, in grams? • how much of the excess reagent will remain after the reaction has been completed? • if 10.5-g of na2so4 are actually recovered experimentally, what is the percent yield?
