8. A sample of cobalt (specific heat of Co=0..418 J/gºC) at 200.0°C is dropped into a calorimeter containing 50.0 mL of water at 21.1°C. The final temperature of the water/cobalt mixture was 67.1°C. What was the mass
of the sample of cobalt?
(Hint: 1 mL of water has a mass of 1 gram)

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

i think its 100

i hope this !
