Pre-Laboratory Assignment 1. Why shouldn't you look directly at burning magnesium? 2. A compound composed of N and O has 2.5 moles of O for every mole of N. Write the empirical formula for this compound. 3. A student used the Procedure of this experiment to determine the empirical formula for an oxide of tin (Sn). He collected the following data: 22.36 mass of crucible, cover, and Sn, g mass of crucible, cover, and tin oxide,g 24.67 24.98 (a) Calculate...

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...

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...

3. A student used the procedure described in this module to determine the empirical formula of an oxide of titanium (Ti). A crucible and crucible cover were heated to a constant mass of 34.749 g. The mass of the crucible, crucible cover, and a sample of Ti was 36.383 g. Following the reaction of the Ti metal with O2, the crucible, crucible cover, and contents were heated to a constant mass of 37 472 g (1) Determine the mass of...

When determining the empirical formula experimentally, you will not know the number of moles directly since we do not have instrumentation that can measure the quantity of moles. Instead the mass can be used. In an experiment it is found that an aluminum oxide sample contains 1.35 g of aluminum and 1.20 g of oxygen. a. How many moles of aluminum...
