Calculate how much heat energy is absorbed by 125 g of water if the water temperature increases from 22.5 °C to 30 °C. The specific heat for water is 4.18J/g °C.

A. 69.7 J

B. 224 J

C. 3.9 J

D. 3,900 J

Displacement is the slope of a velocity vs. time graph a. true b. false

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.

Na chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.
