The enthalpy of formation of C2H5OH is -238.7 kJ/mol. What information does this reveal about the bonds in the molecule? A. Bond Formation in C2H5OH from its elements absorbs energy.
B. Bond formation in C2H5OH from its elements does not occur.
C. Bond formation in C2H5OH from its elements releases energy.
D. Bond formation in C2H5OH from its elements only occurs in cold temperatures.

explanation:

i think option no d is the correct answer

i dont know the answe

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
