Learning how to master multiple choice questions on the AP Chemistry exam is a massive boon to a test taker's confidence and success. Learn about the multiple-choice section of the exam, how to prepare for the test, strategies for taking the test, and tips for solving math-based problem...
In chemistry, if you don't understand stoichiometry and how to convert units to each other, every calculation will be difficult for you. This doesn't apply as strongly in other subjects like history, which tends to be composed more of modular units. Even though I mentioned above that you ...
Calculating how many grams of a substance that you have is important for successfully completing experiments in the laboratory and for solving chemistry problems. The number of grams refers to the mass of the compound. When you are presented with a probl

also,Fe + O2 + H2O---> Fe(OH)3--is this one even possible?? its supposed to be the rusting of iron or something! ive worked so hard! Does your teacher give you steps on how to do these equations? If not then i can give you the steps to solve REDOX reactions. Logged ...
That gives you two equations in two unknowns, solve and you know concentrations of both acid and conjugate base. Then it is just a matter of calculating how many moles of both you need per - say - 1 liter. Logged ChemBuddy chemical calculators - stoichiometry, pH, concentration, buffer ...
To solve the constrained optimization problem, we employed the real-coded genetic algorithm (GA) named IS-SR-REXstar/JGG (see Section 4.3 of Supplementary Information). We performed the parameter estimation on the supercomputer Shirokane3. A single run for the parameter estimation took 12 h ...
