have inspired humanity as much as aerospace engineering. Many of the technological advances that are now part of our daily lives‚ such as handheld calculators and non-stick pans‚ were initially developed to aid in space flight. Today’s aerospace engineers are still working to help us view the edges of the universe as well as improve the way that we live our lives right here on planet earth.” (Peterson’s staff) This quotation proves that Aerospace engineering has changed the world for the better.

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

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

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

is so important in developing software systems‚ software engineers have chance to do good‚ cause harm‚ or to allow others to do bad things. To ensure that they work for the good side‚ software engineers must commit themselves to making software engineering a beneficial and respected profession. In the software world‚ like in ethical world‚ if a good belief exists‚ such as everything will be perfect‚ things can fall completely on the other side. People think‚ and make different decisions‚ but understanding

“A scientist discovers that which exists. An engineer creates that which never was.” It was this quote by Theodore von Karman in my high school physics book that sparked my interest in engineering. Engineering allows for the designing and constructing of structures that most people could only dream of but they could not live without. From bridges spanning oceans to connect countries to artificial islands on which building complexes can provide housing for thousands of people. This notion is what
