How many moles of Fluorine are in 3.0 moles of CaF2?

The enthalpy of formation of water is -285.8 kj/mol. what can be inferred from this statement?

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?

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)]
