Concentrated hcl has a concentration of 12.0m hcl. what volume in ml of this solution would one need to get 0.425 mol of hcl?
a) calculate liter of solutions from molarity and the moles of solute
b) convert l to ml

One does not belong why? ice, gold ,wood ,diamond and table salt

What is true for a substance that releases energy

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)]
