Which contains the largest number of atoms? a. 3.0 x 1022 molecules of nitrogen gas
b. 3.0 mL of CH, OH (density = 1.2g/mL)
C.) 3.0 moles of CO
d. 3.0 g of water

Which of these is not an example of chemical weathering? a. iron-rich mineral rusting b. feldspar turning into clay c. limestone reacting with acid d. granite breaking up into sand

Element before carbon on the periodic table

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)]
