Activity 1 Introduction to Chemical reactions by Trish Loeblein httpphetcoloradoedu Learning Goals Students will be able to Relate the realworld example of making sandwiches to chemical reactions. By: . Shaimaa. . Soarkati. , . CHBE446. Section: 0301. James Clark School of Engineering. Constant Stirred Tank Reactor (CSTR). Steady-state continuous flow of reactants (A) and Products (B). Well-mixed reactor, so exit stream has the same composition as reactants in the tank. Refrigerate leftovers immediately! Do not allow them tocool first on the kitchen counter! Leftovers shouldn Author: Wesley Tung. Technical Things. A chemical equation of a reaction uses mole ratios to describe the production of products from reactants.. In . , hydrogen and oxygen are reactants, and water is a product.. Parts of a chemical equation:. Reactants. : a substance present at the beginning of a chemical reaction. (Left side). Products. : a substance that is produced during a chemical reaction (Right Side). Equilibrium. When a reaction is at a state of equilibrium, the rate of the forward reaction __________ the rate of the reverse reaction.. is equal to. is slower than. is faster than. is the reverse of. by Trish Loeblein . . http://phet.colorado.edu.

Never marinate meat at room temperature. Always keep meat refrigerated until it’s ready to be cooked.. Never reuse a marinade; once it has touched the raw meat it is contaminated. .

Identify the limiting reactant in a chemical equation. Identify the excess reactant and calculate the amount remaining after the reaction is complete. Calculate the mass of a product when the amount of more than one reactant is given. . When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium. This equilibrium is .
