Today we finished the chemical change lab since so many of you left early to take your math SOLs. Then I introduced the end of year project. Here are some resources: Instruction Sheet Storyboard Template How to tell a good story with examples of simple movies! Ideas: (everyday chemistry site – many topics from this […]
Last lab of the year! The point of this lab is for you to connect chemical symbols with what is physically happening in chemical reactions, to review writing, balancing, classifying reactions, determining state symbols, writing formulas.
Warm-up: What is the volume of 1 mole of gas at STP? How many molecules are there in 1 mole? Write the a balanced reaction for the following Aqueous Copper (II) nitrate reacts with aqueous sodium phosphate to produce copper (II) phosphate precipitate and soluble sodium nitrate. Answers: 3 Cu(NO3)2(aq) + 2 Na3PO4(aq) –> Cu3(PO4)2 […]
Important Info: Quiz Next Class: Friday, May 13 (on writing, classifying reactions and stoichiometry) – no review guide. Use the worksheets we’ve done in class. – write reactions given reactants and products (must remember naming for ionic and covalent and acids) – write state symbols (solid, gas, liquid, aqueous) – balance reactions -classify reactions (synthesis, […]
Important Info: Next Quiz: Friday, May 13 (on balancing, classifying reactions and stoichiometry) Warm-up: Magnesium reacts with aqueous sodium chloride, what type of reaction is it? What will the products be for the reaction in #1? Magnesium hydroxide reacts with hydrochloric acid, what type of reaction is it? What will the products be? What are […]
