Consider the equation for the formation of a kidney stone. 2Na3 PO4 (aq) + 3CaCl2 (aq) =
Ca3(PO4)2 (s) + 6NaCl (aq)

Is each reactant bonded ionically or covalently?

How do you know?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
