Question:

Can someone see if I'm right?

Aluminum hydroxide reacts with sulfuric acid according to the balanced equation 2 Al(OH)3 + 3 H2SO4 ? Al2(SO4)3 + 6 H2OIf you react 0.450 moles of aluminum hydroxide with 355 milliliters of 6.0 M sulfuric acid, which reagent is the limiting reactant? How many grams of Al2(SO4)3 can you make?365(1/197)(1/3)(342/1) 211.2135.1(1/78)(1/2)(342/1) 76.95is it Al(OH)3 and the most you could make is 76.05 grams

Answer:

Carbon fiber bikes are much lighter and stronger than aluminum bikes, but if you are only going to use it once in a while I suggest aluminum.
I have aluminum with carbon forks and seat post and I love it.
IMO if you're that far up the price range then go for the carbonCheck out the diamondback podium 5Super light carbon frame at a decent priceStock wheels are meh but that's an easy upgrade down the road
Honestly, it DOESN'T matter what frame material, just how well it's built and design, I have a caad10, super smooth ride, aluminum, better than a lot of carbon bikesBut you can have an aluminum bike from walmart that rides terrible and is complete trashSame goes with carbon, you have good carbon and bad carbonIf I were you, i'd try out as many bikes as possible and not worry about frame materialI mean rodriguez made a 14lb steel bike, and when cyclists hear the word steel they quickly associate it with heavySo don't worry about frame material, just worry about a bike that feels the most comfortable.
2 Al(OH)3 + 3 H2SO4 → Al2(SO4)3 + 6 H2O (0.355 L) x (6.0 mol/L) 2.13 mol H2SO4 2.13 moles of H2SO4 would react completely with 2.13 x (2/3) 1.42 mole of Al(OH)3, but there is not that much Al(OH)3 present, so Al(OH)3 is the limiting reactant( 0.450 mol Al(OH)3) x (1/2) x (342.1527 g Al2(SO4)3/mol) 77.0 g Al2(SO4)3 Your calculations would be correct if you had rounded correctly and reported the correct number of significant digits in the last line.
