L1: What is a mole?
I CAN recognize and understand that when I have a mole of a substance it contains 6.02 x 10^23 particles and a mass that it equal to that found on the periodic table known as its molar mass.
L2A: How to use a mole to count in chemistry?
I CAN use the analogy of the Popcorn Counting Unit “PCU” and know that although the particle amount/ count is the same for every molar sample, the mass of 1 mole of any material is different due to the mass of the individual atom or compound.
L2B: How many moles are in everyday items?
I CAN use the knowledge that 1 mole is equal to 6.02 x 10^23 particles and the substance’s molar mass to convert from one unit to another using everyday atoms and compounds such as salt, sugar and water.
L3: Can I use this chemical counting system to determine chemical formulas?
I CAN use experimental data to determine the ratio of two elements that form a compound to determine the compound’s empirical formula because I understand that atoms are conserved in a chemical reaction.
L4: What is the meaning of a balanced chemical reaction?
I CAN use correct formulas within a balanced chemical reaction to show that mass of reactants and products are conserved in a chemical reaction.
L5: Can I use a balanced chemical equation to predict how much of a product will be produced?
I CAN use the given mass of a reactant to predict the mass of products made using the balanced chemical equation and stoichiometric ratios because of the law of conservation of mass.
L6: How is stoichiometry used to design an air bag?
I CAN use a balanced chemical reaction and stoichiometry to determine the correct amount of baking soda and vinegar to inflate my air bag to a safe volume.
L7: How do you quantify energy in a chemical reaction?
I CAN understand and use the information of temperature changes during a chemical reaction to know if the reaction is endothermic or exothermic. I can be use the understand that energy is required to break bonds and energy is released when a new bond is formed to determine if the overall reaction in endothermic or exothermic.
L8: What is a and how is it useful?
I CAN perform a titration and use the experimental data and my knowledge of mole to mole ratios to determine the concentration of an unknown acid.
