Question
Please don't provide handwritten solution ......
Transcribed Image Text:The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment
Lavoisier found that mercury (11) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas.
1. Write a balanced chemical equation, including physical state symbols, for the
decomposition of solid mercury(11) oxide (HgO) into liquid mercury and gaseous
dioxygen.
0
2. Suppose 28.0 mL of dioxygen gas are produced by this reaction, at a temperature
of 150.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide
that must have reacted. Be sure your answer has the correct number of significant
digits.

- 1. Develop a detailed separation scheme for the separation and determination of the percent composition of your sample which will be a mixture of NaCl, NH.CL, and sand. You are expected to use the properties of the components listed below and some of the techniques listed in the table in the pre-lab queries (and used in Separations I). Keep in mind that any chemistry student should be able to pick up your scheme, understand it, and use it to complete the separation and calculation of % composition. Place the scheme on a separate sheet of paper.
