5. Gasses
learning analysis
In this Unit we learned about formuals such as PV=nRT. P(ressure) V(olume) = n(mol)R(.0821)T(emperature) was really interesting and fun to do It taught us how to find the pressure, the amount of mols, the volume, or the temperature of a gas. In this unit we also learned about stoichiomestry and the law of conservation of matter. stoichiomestry is a chemical recipe that can tell you how many mols a chemical has if it is a compound of two or more chemicals. The law of conservation of matter says "what goes into a reaction must come out of the reaction." I thought this was very interesting and it lead us right into stoichiomestry.

We made caramel with acid. We added acid to the water so that wherever the water vapor goes, it is very hot. because it has a diapol-diapol molecular force, it does not want to be a liquid.
We mixed lead Iodine and KNO3 together to create a ion- diapol molecular force. When they were mixed it turned the lead iodine very yellow
We made a rocket out of a pringles can by adding calcium and water to create hydrogen. we balanced them out by putting 2 hydrogen's per one oxygen in the can and ten we lit it on fire.
These are our notes for PV=nRT and some equations we did using the formula. We used PV=nRT to find different measurements like volume or pressure in a container filled it gas.
These are our notes on the law of conservation of matter, which we used to help us transition into learning about stoichiomestry
These are our notes for when we studied stoichiomestry or "Cheical Recipes" in this section we used stoichiomestry to prove the law of conservation of matter, which says "What goes into a reaction must come out of a reaction
