The initial temperature of a bomb calorimeter is 28.50°
c. when a chemist carries out a reaction in this calorimeter, its temperature decreases to 27.45°
c. if the calorimeter has a mass of 1.400 kg and a specific heat of 3.52 j/(gi°
c., how much heat is absorbed by the reaction?

The answer is 5174400 J.

Explanation:

Here you have to keep in mind the equation to determine the amount of heat  (Q) that one body of mass m can take. The equation is : [tex] Q=mc\Delta T [\tex]

where m is the mass, c is the specific heat and [tex] \Delta T [\tex] the temperature variation. This way: Q=1400kg*3.52J/gºC*(28.5-27.45) ºC=1400000 g*3.52 J/gºC * (28.5-27.45)ºC=5174400J=5174.4 kJ=5.17 MJ.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
