The above picture represents a lab that the Chemistry students did that had them mix 2 aqueous compounds to make yellow paint ( lead iodide). This experiment is called Golden Rain because the compounds switch places with each other to form a precipitate, the yellow you see above.
In the above picture, zinc switches places with copper. This is called a single replacement reaction. The catch is that the element must be more active than another to make this reaction work. Zinc is more active than copper so they switch places to make zinc nitrate and copper.
In the above picture, 4 different types of metals were put to the test to see if they would react with different compounds. The metals were aluminum, copper, zinc, and magnesium. The students had to predict which reactions would take place and why.
In the last experiment of the year, the students had to use their knowledge of moles, compounds, and ratios to predict how much baking soda and vinegar to add to different sizes of ziploc bags to make them explode as nonexplosive as possible. They had to use dimensional analysis and how much the different ziploc bags held with volume to accomplish this. They had to explode a sandwhich bag, quart bag, and a gallon bag.
