How many grams of the reactant water is needed to make 800.00g of calcium carbonate? The balance equation is:
CaCN2+3H2O -> CaCO3+2NH3

What is the mass of 0.46 mol of mgcl2

All motion is caused by force? true or false

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)]
