several properties of the element magnesium are shown. which one is a chemical property?
a.
has a density of 1.7 g/cm3
b.
melts at 650°c
c.
conducts electricity
d.
has a silvery-white color
e.
burns when exposed to heat

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)]
