For the reaction represented by the equation 2H2 + O2 -> 2H20, how many grams of water are produced from 12.12g of hydrogen?
a. 2.000 g
b. 6.000 g
C. 54.00 g
d. 108.0 g

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)]

Why can water dissolve many ionic compounds
