In the reaction :
`2Al_((s)) + 6 HCl_((aq)) rarr 2Al_((aq))^(3+) + 6 C bar(l)_((aq)) + 3H_(2(g))`

Options

A. `6L HCL_((aq))` is consumed for every 3L `H_(2)` produced.
B. 33.6 mL `H_(2(g))` is produced regardless of temperature and pressure for every mole Al that reacts.
C. 67.2 `H_(2(g))` at STP is produced for evey mole Al that reacts.
D. 11.2 L `H_(2(g))` at STP is produced for every mole `HCl_((aq))` consumed.

Answer

A, B, C, D

Explanation

`2Al_((s)) + 6 HCl_((aq)) rarr 2Al_((aq))^(3+) + 6 C bar(l)_((aq)) + 3 H_(2(g))`
6 mole HCl reacts to produce 3 mole `H_(2)`
6 mole HCl reacts to produce `3 xx22.4 L H_(2)` at STP
`:.` 1 mole HCl reacts to produce `11.2L xx L H_(2)` at STP
