Suppose a lab group reports a ppercent yield of sand of 105. is it really possible to collect more sand than was originally represented? what is the possible explanation for the extra product?

List the path of the respiratory system

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?
