We started out class with an experiment Mr. Lieberman did for the class.
He had a beaker of water and put some calcium carbide in it to produce acetylene gas.
After the reaction in the picture above, acetylene gas was produced.
The equation for this experiment was: CaC2 + H2O = C2H2 + CaO
Another experiment was done by taking a plastic tube and acetylene gas and oxygen was put in. After Mr. Lieberman pushed a button on the tube, it produced a large pop sound as carbon dioxide and water was produced.
This reaction is shown by: C2H2 + 5/202 = 2CO2 + H20
This part of the experiment didn't always work every time and give the pop sound.
This experiment was done to show that you need the correct mole to mole ratio in the substances among an equation so that the experiment can be successful. (Like the paint can experiment we did before!)
The Basics of Stoichiometry:
1. Foundation of stoichiometry-molar ratio or A.K.A. mole:mole ratio
2. molar ration is (Moles wanted/moles given) from balanced equation
3. To solve problems, think of it similarly to dimensional analysis
Homework: mole-mole worksheet and quiz on stoichiometry tomorrow
The next scribe will be...Autumn K.
