i did 0.049x2/3=mole of CuCl2 then mole of cucl2/.99 then times by 2 to get 0.0660 but its wrong, the actual answer is 0.148. Can you double check this again why i did it wrong
chemistry
If 0.0490 mol of solid Al reacts stoichiometrically according to the balanced equation with 990 mL of aqueous Cl-, what molarity (M) of Cl- is required? 3 CuCl2(aq) + 2 Al(s) → 3 Cu + 2AlCl3(aq)
chemistry
since heat is added, so does that mean H is positive(endothermic)
chemistry
please check my answer(one with star). The solubility of borax is directly proportional to temperature. Therefore, the sign of H is A. negative* B. positive C. unknown with the given information since solubility shifts the reaction to the right, therefore it is exothermic so H...
