a. How can you get to the empirical formula from percent composition or grams? Use 3.086 percent H, 31.62 percent P, and 65.31 percent O. 10. How do you find the real formula from the empirical formula? a. Use HO with a mass of 17 grams and a real molar mass of 34 g/mol as an example. e. Can you change a formula of a compound to balance an equation? 13. Using 2A 3B D, find the moles of compounds B needed when given 6 mol of compound A. a. Given the aluminum reactions balanced in question 11(h), calculate the amount of aluminum oxide produced when 41.0 g of aluminum are used in the presence of excess oxygen. 14. What is a limiting reagent? 15. Given an amount of substance A and B, how do you calculate which is the limiting reagent? a. Given the aluminum reaction balanced earlier, calculate the limiting reagent when 21.0 g of aluminum are used and 21.0 g of oxygen are used. 19. Write the formula to calculate percent yield. That is not many questions considering there were initially 278 questions (which by the way HAVE been book work questions or I would be in my book not asking you guys). I am going into chem and don't know these yet and am thus asking you guys. Thanks! I would really appreciate any help! Thank you for your help. I want to reassure you that this is only a few of the questions from 278 of them. It is summer hw, and these are the only ones I have left and the ones I wasn't sure about so thank you for helping me understand them Al O2 --> Al203 this is the missing equation to complete the questionIdeas for a school project board game?
I have to create a board game on halogens that teaches people about some concepts. I have the idea of using a periodic table as the game board. Also, there has to be 50 question cards. Does anyone have any good/original ideas that would make the game more interesting/fun/creative? And please don't say make it like Monopoly.
