Question
- K2C2O4is reacted with KMnO4 according to the following chemical equation.
K2C2O4 (aq) + 2 KMnO4 (aq) + 8 H2O → 7 CO2 (g) + 2 Mn(OH)2 (s) + 2 KOH (aq)
- How many grams of K2C2O4is needed to react with 50.0 g KMnO4?
- How many grams of CO2is produced?
- A freezer containing 2.0 kg of ice had a temperature of -5.0 oC initially. Suddenly, a power interruption occurred. Right before the power returned, only 250 g ice was left. Calculate the heat flow of the water during the blackout.
- The industrial method currently used to produce butanol is the hydration of butene.
C4H8(g) + H2O(g) → C4H10O(g)
The enthalpy values for the following reactions are:
4C(s) + 4H2(g) → C4H8(g) ΔH = – 7·1 kJ mol–1
4C(s) + 5H2(g) + ½O2(g) → C4H10O(g) ΔH = – 292·8 kJ mol–1
2H2(g) + O2(g) → 2H2O(g) ΔH = – 483·6 kJ mol–1
Using the data above, calculate the enthalpy change, in kJ mol–1, to produce butanol by hydration of butene.
