Experiment to determine the ity of a free-falling object. Data
are presented in the table.
If the accepted value of acceleration due to gravity is
9.8 m/s2, how would you describe Clara's data?
Measurement
O precise but not accurate

9.3 m/s2
7.3 m/s2
7.5 m/s2
8.9 m/s2
Ok

lol for the pointsss

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.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
