Chemical Formula Principles Chemical Formula is a system of chemical notation that was invented in 181 by John Jakob Berzelius. The system is based on the law of definite proportions”‚ states that all samples of a given chemical compound have the same elemental composition. It is also a way of expressing information about the proportions of atoms that constitute a particular chemical compound‚ using a single line of chemical element symbols‚ numbers‚ and sometimes also other symbols‚ such as

Factors Influencing Rate of Reaction Aim To investigate several effects believed to influence rate of reaction‚ concentration of a substance and temperature‚ and observe the effects. Hypothesis Concentration and temperature will both increase the rate of reaction in accordance with collision theory. Introduction The reaction rate or rate of reaction for a reactant or product in any given reaction can be defined as the speed with which a reaction occurs. For example‚ the oxidation of iron

PROFITABILITY RATIOS RETURN ON INVESTMENT (ROI): The prime objective of making investments in any business is to obtain satisfactory return on capital invested. Hence‚ the return on capital employed is used as a measure of success of a business in realizing this objective. Return on Investment establishes the relationship between the profit and the capital employed. It indicates the percentage of return on capital employed in the business and it can be used to show the overall profitability

Mole Fraction Return to Solutions Menu The mole fraction is: moles of target substance divided by total moles involved The symbol for the mole fraction is the lower-case Greek letter chi‚ χ. You will often see it with a subscript: χsolute is an example. Example #1: 0.100 mole of NaCl is dissolved into 100.0 grams of pure H2O. What is the mole fraction of NaCl? Solution: 100.0 g / 18.0 g mol¯1 = 5.56 mol of H2O Add that to the 0.100 mol of NaCl = 5.56 + 0.100 = 5.66 mol total Mole fraction

Chemical Reactions The idea of chemical reactions was investigated about two hundred and fifty years ago‚ when a man named Antoine Laurent Lavoisier wanted to know about the importance of chemical changes. Also‚ in the 19th century‚ John Dalton made the atomic theory. Dalton said that bonding atoms together makes new substances‚ which is a chemical reaction (History of chemical reactions). The definition of chemical reaction is‚ “the processes in which substances undergo chemical changes‚ which
