31.5 grams of an unknown substance is heated to 102.4 degrees celsius and then placed into a calorimeter containing 103.5 grams of water at 24.5 degrees celsius. if the final temperature reached in the calorimeter is 32.5 degrees celsius, what is the specific heat of the unknown substance?

show or explain the work needed to solve this problem, and remember that the specific heat capacity of water is 4.18 j/(°c x g). (2 points)

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

answer: mole of the gas

answer: mole of the gasexplanation:
