nitrogen
glucose (sugar)
carbon dioxide
chlorophyll
What is one negative effect of producing more ethanol for use as fuel?
An increase in air pollution
People buying fewer cars
Rising prices of certain food
Having to import more oil from abroad
The formulae of molecules present in biodiesel are most likely to be in the range:
C6H14 to C8H18
C8H18 to C21H44
C17H34O2 to C19H38O2
C6H12O2 to C10H20O2
Methane and methanol will both burn in air. The reactions are described by the following equations:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l); Δ H= -890kJ/mol
2CH3OH(g) + 3O2(g) → 2 CO2(g) + 4H2O(g); Δ H= -1452kJ/mol
If two moles of methane and two moles of methanol are completely burnt in separate experiments, which experiment will release the most energy?
(a)
Methane and methanol will both burn in air. The reactions are described by the following equations:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l); Δ H= -890kJ/mol
2CH3OH(g) + 3O2(g) → 2 CO2(g) + 4H2O(g); Δ H= -1452kJ/mol
If each of the above reactions is used to produce 1000kJ of energy, which one will release the most carbon dioxide? Justify your response.
