1.
Which is the standard enthalpy of formation equation for water?
2H2(g) + O2(g) → 2H2O(l)
H2(g) + ½O2(g) → H2O(l)
H+ + OH- → H2O
H2O(g) → H2O(l)
2.
Why do bond enthalpy calculations differ from experimental values?
Mean values are averages over many compounds
Bonds do not break
Hess's law fails
Temperature is too high
3.
25.0 g of water is heated by 10.0 K. Energy transferred is:
1045 J
250 J
418 J
104.5 J
4.
Enthalpy of neutralisation of ethanoic acid with NaOH is less exothermic than HCl with NaOH because:
Ethanoic acid is more concentrated
Energy is used to ionise the weak acid
Water is not formed
NaOH is weak
