At constant volume, the heat of combustion of a particular compound is − 3550.0 kj / mol. when 1.075 g of this compound ( molar mass = 154.74 g / mol ) was burned in a bomb calorimeter, the temperature of the calorimeter, including its contents, rose by 4.073 ∘ c. what is the heat capacity (calorimeter constant) of the calorimeter?

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
