4. A block with a volume of 12 cm has a density of 3 g/cm2. The block is cut into two pieces. One plece has a volume of 8 cm", and the other piece has a volume of 4 cm. What are the densities of the two pieces?
O A. The larger piece has a density of 2 g/cm and the smaller piece has a density of 1 g/cm?
OB. The smaller piece has a density of 2 g/cm and the larger piece has a density of 1 g/cm?
O C. The two blocks both have densities of 1,5 g/cm
O D. The two blocks both have densities of 3 g/cm?

i believe that it is a exoplanet

the answer is d. 74.02

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

i belive it is water
