Calculate the [H3O1+] and pH of a 550. mL aqueous solution made from 0.0130 moles of HCl.

In apex! a liquid heated beyond a certain temperature becomes

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)]

37.0 °c = °f (human body normal temperature)
