What are the most common types of water contaminants

Which type of bonding involves the complete transfer of a valence electron from a less electrogrative atom to a more electronegative one

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

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)]
