The specific heat of liquid water is 4.184 j/g-k. the latent heat of melting (ice to liquid is 6.0102 kj/mol. define q100-0= the amount of heat released by water when it is cooled from boiling to freezing. define freeze = the amount of heat released during the freezing of water. estimate q ratio ? q100-0/qfreeze

An ideal spring has a spring constant (force constant) of 2500 n/m, is stretched 4.0 cm, how much elastic potential energy does it possess? (a) 3j (b) 0.00j (c) 1j (d) 2j (e) 4j

How many molecules are present in 3 mols of silicon dioxide (sio2)?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
