~RALLY~

today we ahd the last rally of the year called the "homegoing"rally. it was fun, because it had plenty of dancing acts and a lot of cheering. the coolest dance groups were "encore" and "academy of villans". the academy of villans are a proffesional dance group that were featured in Americas best dance crew! Amazing right!! THe rally was really kool for the last one evar! well peace out!!!

Oxidation of Magnesium

Yesterday we did a lab in which we oxidized magnesium and ended up with MgO, or magnesium oxide. we burned a magnesium ribbon that was 25.3cm inside a crucible and we ended up with MgO. We were supposed to get .60MgO left, but i only got .50 so watev my group ended up doing it right anyway so no sweat the lab was fun.

solutions and pH test

This particular test on Solutions a pH was pretty hard, because it involved a lot of math, and setting up equations. It was mostly algebra. We used the GxCF to find our answers, which does evolve a lot of thinking, so it was indeed challenging. But it gets easier once you learn how to do it.

solutions and ph

we are learning about ph levels, i know that ph levels 1-6 are acids and ph levels 8-14 are bases. 7 is neutral, and water has the ph. this seems easy but when we did a lab on it it was sort of challenging, because there were specific directions that you needed to follow or you automatically did it wrong. but it is cool none-the-less..... we also learned how certain color represent certain ph levels. yea so this is what we have a test on tomorrow...PEACE OUT FROM THE CHEESER!!

Like Dissolves Like

In Chemistry we are learning about dissolving.
Dissolving is when a solute breaks down in a solvent, to create a solution.
"Like Dissolves Like" is a saying, that chemists use to say that "polar" solutes best dissolve in "polar" solvents, and "nonpolar" solutes dissolves best in "nonpolar" solvents. One cool thing we learned was that water is the universal solvent. We are also learning how to find the %, pph, or ppm of a solute, solvent or solution. ITS PRETTY AWESOME i guess...............

MOLES!!!!!!!!!!!!!!!!!!!!!!!!!!

No not the mole your thinking not the animal or the thing on ur body. Im takin bout the mole in chemistry yes a mole is 6.02x EE23. yes it is a very large number......yes HUGE! my teacher has a video on this term and he is singing a song about it "mole song with c" the song is entertaining. using the mole in equations is pretty hard, but i feel like im getting the hang of it.

Cool lab

we did a lab that involved rubbing a rod with a wool cloth. then we put the rod next to some liquids, the liquids were water kerosine and two other liquids that i dnt remember. the liquids either didnt do nything or they became attracted toward the rod and the liqued curved it was actually pretty cool. the lab overall went by reawlly fast and it was pretty kool.
