HIGHER LESSON. (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Today’s lecture. Introduction. Definitions . (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Lecture 1 – Thursday 1/10/2013. 2. Introduction. Stoichiometry. Stoichiometry. Goal. Calculate quantities of reactants and products needed in chemical rxns using balanced chemical equations.. Using an Equation as a Recipe . Ingredients: . F. rame, . They tell us how much of each substance is involved in a chemical reaction. 2H. 2. + O. 2. .  2H. 2. O. 2 moles of hydrogen react with 1 mole of oxygen to make 2 moles of water. This is useful because now we can use it to work out what mass of hydrogen and oxygen we need and how much water is made. The Mole. REVISION. Formulae tell you how many of each atom are in a molecule.. Different atoms have different masses.. Level 4. NEW LEARNING. Formulae and balanced equations. Formula Mass and the mole. (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Lecture 1 – .

Definitions . conquer the Chemistry EOC: Balancing Equations and Stoichiometry Chemistry TEKS 8 (A) define and use the concept of a mole; 8 (B) use the mole concept to calculate the number of atoms, ions, or molecules in a sample of material; A. General Features of Physical and Chemical Changes. A chemical change (a . chemical reaction. ) converts . one substance into another.. Chemical reactions involve:. Breaking bonds in the . reactants . Use . the coefficients to predict the amount of reactant consumed or product formed. The ratio of the coefficients is a ratio of the moles taking part in a reaction.. Reactants (on the left of the arrow) are consumed. Chapter Objectives. Describe the chemical processes used in biomass production and conversion to biofuels.. Explain balancing a chemical reaction as an application of the . law of conservation of mass. COURSE OUTCOME . :. To . understand the basic units and unit operations in . chemical . engineering. .. Specific Outcome . 1.1.1 . Explain the various systems of units . 1.1.2 . Explain the difference between fundamental and derived units .
