The combustion of what volume of ethane (C2H6) measured at 24.6 degrees C and 756mmHg would be required to heat 849g of water from 26.8 degrees C to 98.9 degrees C?
Glauber's salt, sodium sulfate decahydrate (Na2SO4 * 10H2O) undergoes a phase transition (that is melting or freezing) at a convenient temp of 32 degrees C Na2SO4 * 1o H2O(s) yields Na2SO4 * 10 H2O(l) Change H = 74.4 kJ/mol As a result this compound is used to regulate the temperature in homes. It is placed in pl ...continues
