To identify types of reactions and then choose the appropriate materials to perform those reactions while obtaining qualitative and quantitative data.
We believe that sodium bicarbonate will decompose when heated in a crucible.
Crucible (start weight – 10.37g)
1g Sodium bicarbonate (start weight – 11.37g)
The crucible slowly became red hot as we began to heat it. We also noticed that the sodium bicarbonate began to turn yellow and also began to shrink as time passed. The crucible
After the final weigh in, the crucible with the sodium bicarbonate weighed 11.05g (original weight: 11.37g). The sodium bicarbonate decomposed .32g and transformed into carbon dioxide, water vapor, and sodium carbonate.
1g zinc, 13 drops Hydrochloric acid, well plate
We believe that when a metal meets an acid it will bubble due to the hydrogen gas being released.
Little bubbling halfway through and pieces of metal turned a black-ish color.
Zn + 2HCl --> ZnCl2 + H2
Gather a gram of zinc and a drop of hydrochloric acid
Place the zinc into a well plate
Place 13 drops of hydrochloric acid into well plate
