Question

4 gm propane and 48 gm o2 ard allowed to react to the maximum possible extent to form​

Answer 1

Answer:

The combustion change is as follows:

                                    C3H8+(7/2)O2→3CO+4H2Ol

Moles before reaction:  4443214

Moles after reaction:     0; [3214−444×27];443×4; 444×4

                                                                             (see mole ratio of reaction)

∴ Moles of CO formed = 44(3×4)

∴ Moles of CO formed = 44(3×4)×28=7.636 g.

Therefore, the nearest integer is 8.
