What volume of O(2) at 2.00 atm pressure...

What volume of `O_(2)` at 2.00 atm pressure and `27^(@)C` is requried to burn 10.0 g of heptane `(C_(7)H_(16))` ?
`C_(7)H_(16) + 11 O_(2) to 7 CO_(2) + 8 H_(2)O`

Text Solution

Verified by Experts

`C_(7)H_(16)+11O_(2)to7CO_(2)+8H_(2)O`
11 mol of `O_(2)` is required to burn 1 mol of `C_(7)H_(16)`.
therefore, mole of `O_(2)` required to burn 10 g of `C_(7)H_(16)`
`(1)/(10)xx11=1.1mol`
Volume of `O_(2)=PV=nRT`
`thereforeV=(nRT)/(P)=13.5L`

What is the mass of water (in g) produced from 445 g of C_(57)H_(110)O_(6) in the following reaction? 2C_(57)H_(110)O_(6)(s) + 163 O_(2)(g) to 114 CO_(2)(g) + 110 H_(2)O(l)

Equal volumes of C_(2)H_(2) and H_(2) are combusted under identical conditons. The ratio of evolved in i.e. for C_(2)H_(2) and H_(2) is: H_(2)(g) + 1/2O_(2) (g) to H_(2)O(g), DeltaH=-241.8 kJ C_(2)H_(2)(g) + 21/2O_(2)(g) to 2CO_(2)(g) + H_(2)O(g), DeltaH = -1300 kJ
