Answer:
change in the total mass of substances
Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance.
"Function. The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle."

Answer: 
with four significant digits.
Explanation:
Given,
= 178.5 KJ/mole = 178500 J/mole (1kJ=1000J)
= 161.0 J/mole.K
According to Gibbs–Helmholtz equation:
= Gibbs free energy
= enthalpy change
= entropy change
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
As per question the reaction is spontaneous that means the value of is negative or we can say that the value is less than zero.
Thus
Significant figures are the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Thus the temperature is in kelvins above which this reaction is spontaneous.
