![]() ![]() ![]() From this, I now know that I would need 3.914 moles of O 2, or 125.2 grams, to burn all of the B 2H 6:Ī great place to find basic information about a significant historical figure or event is Wolfram|Alpha. Wolfram|Alpha balances the equation and calculates the answer, which is displayed conveniently in a table. In this case, I just enter the following: I have 36.1g B 2H 6 and I need to calculate how many grams of O 2 would be necessary to burn all 36.1g of B 2H 6. To calculate a reaction’s stoichiometry, enter the reaction as well as the amounts you know.įor example, let’s use the reaction B 2H 6 + O 2 → B 2O 3 + H 2O. Thankfully, Wolfram|Alpha can also calculate stoichiometric problems-finding the amount of a substance needed to complete a reaction as well as the theoretical yields. Stoichiometry was for me one of the hardest parts of chemistry classes, and I’m sure I’m not alone. I hope you will find these to be useful both inside and outside the classroom! 1. Here are 15 applications of Wolfram|Alpha in topics beyond mathematics. Because I was a biology major, many of the areas in which I most frequently sought information were related to scientific fields such as chemistry, but Wolfram|Alpha can be a valuable resource in so many more areas. Thinking back on those late-night study sessions, I would have saved a lot of time if I had properly used Wolfram|Alpha as a study tool. I was up late at night making flashcards for tests and searching desperately through Yahoo! Answers, trying to find information like what exactly the alimentary system does (hint: it “functions in food ingestion and digestion absorption of water and nutrients secretion of water, acids, enzymes, buffers and salts waste excretion and energy storage”- thanks, Wolfram|Alpha!). Class lectures moved at a fast pace, and often my notes had gaps in them where I hadn’t finished writing down what the professor was saying before she moved on. I entered college as a biology major and was quickly overwhelmed with the amount of information I had to memorize. We all know Wolfram|Alpha is great for solving calculations and math problems, but not everyone knows about the full breadth of useful data it provides. ![]()
