Chem 160 A

An experiment is run where a silvery substance exhibiting metallic properites was heated at 500°C. After heating for 5 minutes a new powdery substance with non-metallic properties was formed. The new non-metallic substance is known as Tron. The mass of the new non-metallic substance, Tron, is less than the original metallic substance. Based on this experimental information answer the following questions. 


a. Which substance was more likely an element?


b. Explain why you think that substance is an element.

  • I need helppp with my AP chem lab

    Purpose: To calculate the amount of AgNO3 present in an unknown solution of water through the process of gravimetric analysis with NaCl.   Background: Have you ever had difficulty lathering soap or find that the scum in your shower constantly needs to be removed? These are signs of “hard water.” Soap does not lather well in hard water because metal ions, such as Ca2+, form precipitates, creating “soap scum.” A precipitate is an insoluble compound that forms when soluble ions in...

    Objective Find the ratio of moles of reactant to moles of a product for the reaction below. Compare mass and mole amounts of reactants to determine the amount of products that can be/are made. Background Chemical reactions are represented by balanced chemical equations. Proper interpretation of an equation provides a great deal of information about the reaction it represents and about the substances involved in the reaction. For example, the coefficients in a balanced equation indicate the number of moles...

    than other labs. These are toxicity, volatility, and flammability. We routinely use toxic organic solvents like methanol and acetone that are volatile (have low boiling points), but even solid organic materials can produce vapors that may be toxic. Furthermore, organic materials are flammable, and solvent vapors in the air can and do produce explosive mixtures. You should take some general precautions when doing organic chemistry: Do not get solutions on your skin. You do not need to always wear gloves...
