Learning Goal 4: Use molar relationships in a balanced chemical reaction to predict the mass of product produced in a simple chemical reaction that goes.
Thermochemistry. Specific Heat Formula c p c p = Specific Heat Q Q = Energy (heat) lost or gained T T = Temperature change m m = Mass.
Unit 3B. 09. An experiment was carried out to prepare iodoethane, CH 3 CH 2 I. Procedure 1. Put some solid, moist red phosphorus into a flask. 2. Add.
Moley, moley, mole… Objective: SWBAT perform stoichiometric conversions from mole to mass, from mass to mass Catalyst: What is.25 of a dozen?
6.02 X 10 23 representative particles The Mole (also known as Avogadro’s number!)
Chemical Quantities: Stoichiometry. Mole Ratios Intro Analogy Let’s make some sandwiches. 2 pieces bread + 3 slices meat + 1 slice cheese 1 sandwich.
