* Chemical Formulas and Reactions . . . Midterm Objectives: * To balance chemical equations. * To interpret chemical reactions. * To understand equilibrium reactions and the factors that can affect them. * Molecular Mass / Formula Mass * Is the sum of the atomic masses of all the atoms present in one molecule of that compound. Example: the molecular mass of sodium bromide‚ NaBr‚ is 103‚ which represents the sum of the atomic mass of sodium (23) plus that of bromide (80)

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section

Chemical Engineering Chemical Engineering is the branch of engineering concerned with the design and operation of industrial chemical plants. I have been interested in chemical engineering at a young age because I have plenty of engineers in my family. I was influenced by my family to go into engineering because I witnessed how much my family worked‚ and how much it is able to support my family. Becoming an engineer ensures me of a stable job‚ and I will be financially stable. Chemical engineering

the normal range at around 5 seconds after hyperventilation started. The acid/base imbalance indicated by the pH value was respitory alkalosis 7. Did the PCO2 level change during the curse of this run? If so‚ how? Yes. Progressively dropped. 8. If you observed an acid/base imbalance during this run‚ how would you expect to renal system to compensate for this condition? Hypoventilation causes an increase in Pco2‚ generation of H+ causes a decrease in plasma pH‚ secretion of HCO3- into urine

1. You don’t have to be a chem whiz * Chemical engineering requires a basic understanding of chemistry‚ physics‚ math. You’re not required to memorize formulas‚ it’s more important to understand the principles and learn how to apply them to solve a problem/improve status quo. However after a few semesters‚ your brain WILLremember many formulas! * You do need to be analytical and have the ability to think critically. You must be able to look at the problem from a bigger viewpoint but
