Stoichiometry involves using balanced chemical equations to relate the quantities of reactants and products in a chemical reaction. By applying stoichiometry, one can predict the amounts of products formed in a reaction based on the amounts of reactants used. This helps in determining the theoretical yield of a reaction.

Where did stoichiometry originate?
It could be argued that the concept of stoichiometry was first formally stated by John Dalton, who stated as part of his Atomic Theory that:Atoms of different elements combine in simple whole-number ratios to form chemical compoundsIn chemical reactions, atoms are combined, separated, or rearrangedTaken together, these statements pretty much describe the concept of stoichiometry.
What is the history of stoichiometry?
The word stoichiometry derives from two Greek words: stoicheion (meaning "element") and metron (meaning "measure"). Stoichiometry deals with calculations about the masses (sometimes volumes) of reactants and products involved in a chemical reaction. It is a very mathematical part of chemistry, so be prepared for lots of calculator use. Jeremias Benjaim Richter (1762-1807) was the first to lay down the principles of stoichiometry. In 1792 he wrote: "Die stöchyometrie(Stöchyometria) ist die Wissenschaft die quantitativen oder Massenverhältnisse zu messen, in welchen die chymischen Elemente gegen einander stehen." [Stoichiometry is the science of measuring the quantitative proportions or mass ratios in which chemical elements stand to one another.]
What is the definition of stoichiometry?
Stoichiometry is the calculation of relative quantities of reactants and products in chemical reactions based on the principles of conservation of mass and the molar ratios of the substances involved. It helps determine the amount of each substance needed or produced in a chemical reaction.
How do you solve stoichiometry?
You don't solve stoichiometry. The questions and answers that arise in stoichiometry are merely manipulations of permanent relationships between things (e.g. there are approximately 70.9 grams in one mole of chlorine gas). The conversions needed to report an answer of a stoichiometric problem are the part that take work to overcome mentally. One has to evaluate the units that a value starts with and the units the final answer requires and think about what conversions are needed in between.
What number do you place to the left of the formula for a substance taking part in a reaction?
The number placed to the left of a formula in a chemical equation is the coefficient, which represents the stoichiometry or the ratio of moles of each substance involved in the reaction.

How marketing research is part of marketing strategy?
Marketing research is necessary to effectively continue and justify the deployment of a marketing plan into a specific geographic or demographic market. You need research to predict outcomes of marketing efforts.

What is the ratio of the number of equally likely outcomes in an event to the total number of possible outcomes?
You find the total number of outcomes by adding the first part of the odds to the second part of the odds. For example: 1:1 The total number of outcomes would be 2. To find the ratio of equally likely outcomes to the total number, find the number of outcomes, and put it on the left of the semicolon. Then put the total number on the right side. For the same example: (outcomes)->1:2<-(total)
What is the purpose for the NIH Stroke Scale?
The NIH Stroke scale is a tool used by medical professionals to evaluate a patient's neurological deficits following a stroke. This tool is used in part to predict what the patient's short and long term outcomes will be.
