I need to write a balanced ionic equation for Aluminum reacts with dilute sulfuric acid and the balanced ionic equation of aluminum reacts with dilute hydrochloric acidI have been stuck on these two problems for the last 2 hoursPLease can you give me the answers and tell me how you did it.
1st problem: Basic reaction: Al + H2SO4 - Al2(SO4)3 + H Then I balanced: 2Al + 3H2(SO4) - Al2(SO4)3 + 6H Then, cancel out the aqeuous ionsYou end up with: 2Al (s) + 6H+ - 2Al3+ (aq) + 6H Second problem: Basic reaction: Al + HCl - AlCl3 + H Then I balanced: Al + 3HCl - AlCl3 + 3H Then, cancel out the aqeuous ionsYou end up with: Al (s) + 3H+ (aq) - Al3+ (aq) + 3H ALWAYS REMEMBER THAT IF THE COMPOUND IS AQEUOUS, YOU CAN CROSS IT OUTIF IT'S SOLID, LEAVE IT ALONEHOPEFULLY THAT HELPS :)
You can't make it entirely with aluminum foil, but yes, it is possibleYou can make a coil - which is any metal wound on a cylindical fashionYou can make a capacitor which is too metal opposing each otherWhen you connect both of them in parallel, you get a resonance circuit - iedial on the radioFrom there, you can use a diode and (for simplicity sake, cutting out the details) extract the audioFeed that to a high-impedance earphonevoilaCrystal Radio! To make an aluminum foil capacitor, you put aluminum foil on a flat surfacePlace a sheet of plastic over itThen place another sheet of aluminum foil on top of itBasically you made a sandwhichWhen you slide the top foil, you change the part that overlaps the bottomCombined with a coil, you can tune to different station that wayYou need to look up (web search) on Crystal RadioYou can find lots of hitsThat's basically what you are making.
