Consider the following reactioin, 2Al(s) + 6HCl(aq) to 2Al^(3+)(aq) + 6Cl^(-)(aq) + 3H_(2)(g) Which of the following statements is incorrect?

Answer»

6 L HCl (AQ) is consumed for EVERY `3LH_(2)`(g) produced
33.6 L `H_(2)`(g) is produced regardless of temperature and pressure for every MOLE of Al that reacts
67.2 L `H_(2)` L `H_(2)`(g) at STP, is produced for every mole of AI that reacts
11.2 L `H_(2)` (g) at STP, is produced for every mole of HCl (aq) consumed

Solution :2 moles of Al produce `=3xx22.4L`of `H_(2)` GAS
`therefore`1 mole of Al will produce `=(3xx22.4)/(2)=33.62L` of `H_(2)` gas
