Explanation:

a chemical reaction that absorbs energy is known to be endothermic since heat is being taken in by the reaction. The value of the transition state would be 150 because you have to subtract the product's enthalpy and the reactant's enthalpy to obtain it. A positive value for the transition state also corroborates that the reaction is endothermic.

Determine the mass of an object that has a volume of 88.6 ml and a density of 9.77 g/ml.

Nostrana [21]

Given:
The volume is V = 88 mL
Density, d = 9.77 g/mL

Because mass = volume * density, therefore the mass of the object is
$m = (88.6 \, mL)*(9.77 \, \frac{g}{mL} )=865.62 \, g$

Answer: The mass is 865.2 g or 0.865 kg
