Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

lobe of the brain can cause an individual to develop different impulses and as well impulsive behavior (Schwartz‚ 2012). There are even disorders and illnesses such as Depression‚ Schizophrenia‚ and Bipolar Disorder believed to be the result of chemical imbalances in the brain. However‚ biological factors can also determine decisions and actions. Pharmaceutical medications have shown that people make different decisions when on the medications versus when not on them. Individuals treated for attention

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

public taxes; the MLB as a whole brought in $132 million in 2005 of operating income‚ which jumped to $360 million of in 2006 (Orzanian). The overlapping schedules make the National Football League the most competition the MLB has for viewers. Key Issues: In 1994‚ the league tried to impose a salary cap on the professional players‚ this action resulted in a player strike. This strike lasted into the 1995 season‚ before the teams decided to impose a “luxury tax”‚ which taxes the teams who have an

CHM1022 Tutorial 2 – Semester 2‚ 2012 (Chemical Equilibria) 1. The reaction 2 HCl(g) +I2(s) [pic] 2 HI (g) + Cl2(g) has Kc = 1.0 x 10-34 at 25˚C. If a 1.00 L reaction vessel initially contains 0.100 mol of each HCl and solid I2‚ what are the concentrations of HI and Cl2 at equilibrium? 2. Consider the following gas-phase reaction and equilibrium constant at 25 oC: 4 HCl(g) + O2(g) [pic] 2 Cl2(g) + 2 H2O(g) The concentrations of all species were measured at a particular

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice

know is history and‚ as much as possible‚ it’s language‚” said by a filmmaker‚ Alanis Obomsawin. Ultimately in this novel‚ The Inconvenient Indian; A Curious Account of Indian People in North America by Thomas King‚ it illustrates how Natives are faced with many challenges throughout their lives. Colonialism displays how the Europeans were the start of affecting their history.

Chapter 6 - Answer Key to Section Review 1-3 Section Review 1 1. What is the main distinction between ionic and covalent bonding? Answer (A): Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms. Translation: -Ionic bonding happens between a metal and a non-metal (east coast and west coast) -One atom completely donates its valence electrons to another atom -Metals
