5.00 g of molten nacl is at its melting temperature. the salt is added to 25.00 ml water at 25.0 °c in a coffee cup calorimeter. the salt becomes solid and the temperature of the water increases to 47.9 °c. a) calculate the amount of heat transferred.

heat absorbed by water = 2.39 KJ

Explanation:

given,                                    

mass of molten NaCl = 5 g

mass of  water = 25 g                    

Temperature of water = 25.0 °C

Temperature increased to = 47.9 °C

heat absorbed by water = m S ΔT

 S is specific heat in J/gm °C                

 Specific heat of water = 4.184 J/gm °C

 m is mass of water                                            

heat absorbed by water = 25 x 4.184 x (47.9-25)

                                         = 25 x 4.184 x 22.9

                                         = 2395.34 J

heat absorbed by water = 2.39 KJ

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
