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

Introduction Career in mechanical engineering involves grappling with various aspects of the technical and practical work. The job of a mechanical engineer involves widespread handling of machines and components which have a direct relation with power by producing it‚ transmitting it or even making use of power. The major concern of mechanical engineers is bent towards ways and mechanisms through which natural energy sources are converted into uses of practical nature. As part of their work‚ mechanical

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

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.

Analysis of a Chemical Reaction Purpose: To observe a chemical reaction and to use qualitative and quantitative evidence to identify this reaction from among four possibilities. Hypothesis: I think the result is going to produce water. I think this is going to happen because there is hydrogen and oxygen inNaHCO3. Materials: -Test tube clamp - 150 mm test tubes (2) - burner - retort stand - clay triangle - iron ring - crucible Procedure: Part A: 1. Add 0.5 g of NaHCO3

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

Sound Engineering Technicians After looking into jobs in the field of audio and visual technology‚ I have found the job that I would like to look more into. Sound engineering is what makes all the songs we listen to everyday sound as clear and crisp. People in this career have to run sound boards‚ match lyrics to tracks‚ and enhance the sound so it sounds best.2 Employees also have to‚” confer with producers‚ performers‚ and others to determine and achieve the desired sound for a production

“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
