Weekly Blog : Victor N. 7A Image Location Summary This week, we have learned many things. For example, we learned how to balance chemical equations and learned about different chemical reactions. On Monday, we did experiment. We combined baking soda and water together, it became colder. We combined sodium chloride together, it became warmer. When combining the two, it became room temperature. For the next two class periods, we had this worksheet that helped us practice. I learned that you first have to list out the variable, and draw boxes around the chemical formula. In this list, we compare how many atoms on the reactant and the product side. Since I am good at math, it was kinda easy for me to find the greatest common factor. The next two class periods, we did the chemical reactions. We learned about 4 reactions, synthesis, decomposition, single and double displacement. I learned that synthesis is when two or more elements combine into a more complex compound, decomposition

Weekly Blog : Victor N.  7A Image Location Summary This week, we have learned many things. This week, we had block schedule due to testing, so only had this class Tuesday, Wednesday, and Friday. On Tuesday, we finished up some notes about the organizations of the periodic table. I learned that there are 8 groups. For group 1 that has 1 electron in the outer shell, it goes to group 8 with 8 electrons. We then completed a worksheet, while completing a game. In the game, there are hints that you have find out the element. For example, if this element is stable, and has 3 electrons etc.. On Wednesday, we did a worksheet about mixtures, compound, substances, and elements. This worksheet, was kind of review from when we did the Matter Classification Chat. A compound is made of 2 or different elements. A mixture is a substance made by more than 1 type of atom. An element is a substance made entirely of 1 type of atom.A pure substance is a substance made by one type of atom. On Fri
