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

eye is to be one of the fastest hunters of prey on Earth. The twenty two fleshy tentacles attached to the nose of the Star-nosed Mole are incredibly sensitive to touch and aid the mole in capturing prey. Just how beneficial is the snout of a Star-nosed Mole exactly? They could touch a pin head with their nose six hundred times at once. Crazy enough in a single day‚ this mole can consume up to its own body weight in worms and insects. They as well dig tunnels underground and are a valuable aspect to

10/19/2011 Akruti Patel Lab Report #4: Determination of a chemical formula: the empirical formula of Magnesium Oxide 1. Purpose: Determine the empirical formula of magnesium oxide from the percent composition (this can found using the Analytical Method and the Synthesis Method). 2. Introduction: In the late eighteenth century‚ combustion has been studied extensively. In fact‚ according to Steven and Susan Zumdahl‚ Antoine Lavoisier‚ a French Chemist‚ performed thousands of combustion experiments

reported on the financial statements. 1) Return on Equity: One of the most important profitability ratios is return on equity (ROE). ROE is the amount of net income returned as a percentage of shareholders equity. Return on equity measures a corporation’s profitability by revealing how much profit a company generates with the money shareholders have invested. The return on equity ratio is computed as follows: Return on Equity = | Net Income | | Average Shareholder’s Equity | Simply

substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately aged for delivery.2 The objectives of this experiment are to successfully perform an accurate acid-base titration‚ determine moles using molarity and volume‚ and use the total mass and moles of hydronium to determine the equivalent mass.

Current Ratio: The current ratio gauges how capable a business is in paying current liabilities by using current assets only. Current ratio is also called the working capital ratio. A general rule of thumb for the current ratio is 2 to 1. However‚ an industry average may be a better standard than this rule of thumb. So‚ according to the information that we got‚ in 2007 Beximco Pharmaceutical’s current ratio was 1.80 which declined to 1.10 in 2008 and ultimately in 2009 it boosted up to 2.97‚ that
