Best ResponseYou've already chosen the best response.0Which of the following pairs does not share the same empirical formula? C2H6 and C4H12 C3H6O3 and C2H4O2 C3H8O and CH2O C2H6 and CH4? Chemistry ASAP

Best ResponseYou've already chosen the best response.0Yes, your first question is D. Because Zn is less reactive than Ba. You can check it in the activity series list.

Best ResponseYou've already chosen the best response.0So Zn will never replace Ba

Best ResponseYou've already chosen the best response.0If 4.0 miles of X and 4.0 moles of Ay react according to the hypothetical reaction below, how many miles of the excess reactant will be left over at the end of the reaction? 2X + 3Y ==> Xsub2Y sub 3 1.3 y left over 2.7 y leftover 1.3 x left over 2.7 x left over I'm thinking C but I'm not sure

Best ResponseYou've already chosen the best response.0In the second one you just have to simplify. a) C2H6  C4H12 / They both come from the same empiric formula CH3 (see if i multiply CH3 by 2, i get the first formula and if do it by 4 i get the other one) b) C3H6O3 C2H4O2 / Empiric formula for this pair is CH2O, 1st is multiplied by 3 and 2nd is multiplied by 2 Feel free to do the other one. Hint: U can't simplify 1 atom. Like i didnt keep reducing CH2O or CH3

Best ResponseYou've already chosen the best response.0Ok so D does not reduce right?

Best ResponseYou've already chosen the best response.0I don't think you're even trying. About your third question Indeed, 1.3 moles of X are left over, and Y is the limiting reactant, because if you wanted to react 4 mol of X you would need 6 mol of Y, which you dont have.

Best ResponseYou've already chosen the best response.0Go for C, since they maybe made a mistake at D and typed C2H6 instead of C2H8.

Best ResponseYou've already chosen the best response.0Your right! These are the choices. 1. C2H6 & C6H18 2. C3H6O3 & C2H4O2 3. C3H6 & CH4 4. CH2O & C3H6O3
