Answer to Question #67979 in General Chemistry for Julia

Question

1. Calculate the magnitude of the heat energy (Joules) gained by a 360 g sample of ethanol that goes from a temperaturenof 30.1 degrees celsius to 75.5 degrees celsius.
2. Calculate the initial temperature (degrees C) of a 2.50 g sample of aluminum that has a final temperature of 33.3 degrees celsius and lost -25.9 J or heat energy.
3. Calculate the specific heat capacity (J/g*degrees Celsius) of iron, if a 33.4 g sample gained 52.5 J of heat energy in going from an initial temperature of 6.10 degrees C to a final temperature of 9.60 degrees C.
