Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

dividend of $40 for the current year‚ what is the approximate present value of this stock‚ given at discount rate of 5% and a dividend growth rate of 3%? Answer: P = $40/(0.05 - 0.03) = $40/0.02 = $2‚000 Topic 2: Supply and Demand 1) Suppose that the demand for oranges increase. Explain the long -run effects of the guiding function of price in this scenario. Answer: In the long run‚ the higher price of oranges will signal more firms to enter the orange market‚ as it will seem

Chapter 22 The Demand for Money T 1) Multiple Choice The quantity theory of money is a theory of (a) how the money supply is determined. (b) how interest rates are determined. (c) how the nominal value of aggregate income is determined. (d) all of the above. Answer: C Question Status: Previous Edition 2) Because the quantity theory of money tells us how much money is held for a given amount of aggregate income‚ it is also a theory of (a) interest-rate determination. (b) the demand for money

Quadratic Equations Equations Quadratic MODULE - I Algebra 2 Notes QUADRATIC EQUATIONS Recall that an algebraic equation of the second degree is written in general form as ax 2 + bx + c = 0‚ a ≠ 0 It is called a quadratic equation in x. The coefficient ‘a’ is the first or leading coefficient‚ ‘b’ is the second or middle coefficient and ‘c’ is the constant term (or third coefficient). For example‚ 7x² + 2x + 5 = 0‚ 5 1 x² + x + 1 = 0‚ 2 2 1 = 0‚ 2 x² + 7x = 0‚ are all

substance formed after a chemical reaction is called product. Chemical Equation: Representation of chemical reaction using symbols of substances is called chemical equation. Chemical Equation is a way to represent the chemical reaction in concise and informative way. Chemical equation can be divided into two types – Balanced Chemical Equation and Unbalanced Chemical Equation. Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both side. According to
