What Metal Oxide Has Been Formed? Final Lab Submission Purpose: The main purpose of this lab is to weigh and find out how oxidization has taken place along with calculations. Experimental Data: Mass of dry crucible = 31.373 Mass of metal = 0.0318 Mass of crucible and metal = 31.404 g Mass of crucible and metal after experiment = 31.418 Discussion: 1. Based on what you know about the...

Pestlab questions 1. Knowing what you do about magnesium and oxygen, what type of compound (lonie or covalent) should form between these two elements? If you expect an ionic compound, comment on what ions will be bonding together, and in what ratio you expect based on their charges. Also, if that wasn't the ratio you obtained in your experiment, comment on possible sources of error 2. A student starts with a 3.96 sample of manganese (Mn, molar mass is 54.94...

1) A fellow named Jim is trying to prank one of his coworkers, Dwight. Jim thinks it would be a good idea to use a thermite reaction to melt a hole through Dwight's car. Jim doesn't know much chemistry, so he just mixes together all of the aluminum powder and iron (III) oxide he has, which is 300 g 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...
