Im working on some problems in class and I'm finding them difficult. If someone can help that would be appreciated.
A. The real reaction occurring is 2 C2H6 + 5 O2 --> 4 CO2 + 6 H2O. What is the reaction type?
B. You are trying to vaporize 20.5 g of water to make steam. How much energy will you get out of the vaporization process?
C. You found out that a temperature change of 20.0°C caused 16.25g of liquid water to produce energy. How much energy did that temperature change produce?
D. You figured out that 11.2g of liquid water can release 13333 J of energy. What was the temperature change for this reaction?
E. Based on the following reaction, calculate the amount of heat that would be produced from reacting 2.56 mol of iron (II) nitrate with zinc. Fe(NO3)2 + Zn --> Zn(NO3)2 + Fe ΔH= -706.1 kJ
