__**Mendeleev: Predicting the Future?**__


 * Purpose**: The purpose of this lab was to predict the density of an element we had not previously measured.


 * Data:**
 * __Element__ || __Trial__ || __Mass(g)__ || __Volume change(mL)__ || __Density(g/mL)__ || __Average density(g/mL)__ ||
 * || 1 || 2.58 || 1.9 || 1.36 ||  ||
 * __**Lead**__ || 2 || 3.82 || 2.4 || 1.59 || 1.66 ||
 * || 3 || 6.37 || 3.1 || 2.05 ||  ||


 * __Element__ || __Trial__ || __Mass(g)__ || __Volume change(mL)__ || __Density(g/mL)__ || __Average density(g/mL)__ ||
 * || 1 || 5.65 || 1 || 5.65 ||  ||
 * **__Tin__** || 2 || 7.11 || 1.2 || 5.93 || 5.99 ||
 * || 3 || 9.59 || 1.5 || 6.39 ||  ||


 * __Element__ || __Trial__ || __Mass(g)__ || __Volume change(mL)__ || __Density(g/mL)__ || __Average Density(g/mL)__ ||
 * || 1 || 9.95 || 1 || 9.95 ||  ||
 * __**Silicon**__ || 2 || 19.32 || 2 || 9.66 || 9.49 ||
 * || 3 || 26.86 || 3 || 8.95 ||  ||


 * Conclusion:** With our percent errors we were not able to accurately predict germanium. But with the the right results this element density can be easily predicted.

Purpose: The purpose of this lab was to see if matter was conserved, created or destroyed.
 * Products || Mass (g) ||
 * Mass of beaker A & filter with compound || 30.6761 ||
 * Mass of compound recovered in beaker A || 2.3501 ||
 * Mass of beaker B+ compound || 32.4142 ||
 * Mass of recovered compound in beaker B || 1.2345 ||
 * Total mass of both A & B compounds || 3.5846 ||

Conclusion:no, our results did not confirm the conversation of mass. We had more mass in the compounds after the reaction than before it. We had a 84% error. The average error of other groups was 94%.
 * Reactants || Mass (g) ||
 * Mass of empty beaker A || 28.8326 ||
 * Mass of compound in beaker A || .7504 ||
 * Mass of empty beaker B || 31.1796 ||
 * Mass of compound in beaker B || 1.2002 ||
 * Total mass of compounds in both beakers || 1.9506 ||
 * Mass of clean filter paper || .8885 ||

The killer would have most likely been Penelope page. When you plug in 9.8 for y, it comes out to 63 inches. Since her height was 5 foot 4 inches, it was the closest height shoe size that fit the range of the description (9.8 to 11 inches) the best.
