CHEMISTRY TOPIC 11 CHEMICAL CALCULATIONS CHEMICAL CALCULATIONS INTRODUCTION The first part of this ‘Chemical Calculations’ topic will help us to work out QUANTITIES involved in a reaction; For example‚ a manufacturer might want to know‚ How much ammonia will I produce from 20 tonnes of nitrogen in the Haber Process? To do these calculations you will need to be familiar with the term Ar (relative atomic mass)‚ Mr‚ Molar mass and Mole. Relative Atomic

Describing friend’s character. I have a friend‚ his name is Dima. I know him about five years. He amazed me by his intelligence and brainy. He knows the answer on any question. Even if he doesn’t know the correct answer‚ he’ll find the way to explain it. I appreciate his optimism and indifference at the same time. When something bad has happened‚ he is always determined. He says that next time he would be more sense and had learned a lot from that situation. And next day he behaves as if nothing

velocity of the stream using Equation 1. (Eqn. 1) Where is the flowrate in m3/s and A is the cross-sectional area of the pipe. To find the flowrate‚ we multiply the flowmeter reading by the constant and convert from gallons to cubic meters as follows: The cross sectional area of the 7.75mm pipe is Plugging these values into Equation 1‚ we obtain a bulk velocity . With the bulk velocity value‚ we can find the Reynolds number of the flow using Equation 2. (Eqn. 2) Plugging

The media equation is a theory developed by two professors of communication‚ Byron Reeves and Clifford Nass‚ at Stanford University. The theory is simple. They state that people treat the media as if they were real‚ hence the equation: media = real life. Basically Reeves and Nass are saying that people on an unconscious level perceive the media as real. People view objects of the media are talking to them personally. Reeves and Nass view things such as computers‚ televisions‚ radios‚ and other

This article is about quadratic equations and solutions. For more general information about quadratic functions‚ see Quadratic function. For more information about quadratic polynomials‚ see Quadratic polynomial. A quartic equation is a fourth-order polynomial equation of the form. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. Monomial – is a polynomial with only one term. Binomial
