H In a similar experiment, tin was burned in air. Calculate the empirical formula for the oxide of tin using the following data: Mass of crucible, cover and tin sample = 21.76g Mass of empty crucible with cover = 19.66g Mass of crucible, cover and sample after heating = 22.29g
Mass of empty crucible with cover Mass of crucible, cover, and tin Mass of crucible, cover, and sample after reaction and prolonged heating 19.66 g 21.76 g 22.33 g A similar experiment was used to determine the empirical formula of an oxide of tin (Sn). Use the data provided to answer the following question. Calculate the number of moles of tin in the oxide of tin sample. Gaseous ammonia (NH3) reacts with gaseous oxygen to form gaseous nitrogen monoxide and...
As a result of this procedure, anything that was in the crucible at the end of the experiment, along with the magnesium oxide product, would cause an error in the figure that is recorded as "mass of oxygen". Would extra mass it the crucible cause the "mass of oxygen" to come out too high or too low? Explain. Here are some data from a similar experiment, to determine the empirical formula of an oxide of tin. Calculate the empirical formula...
