You need to calculate the enthalpy change (AH) of the reaction A + B → C.
How can the enthalpies given for the reaction steps below be combined to
give the overall change in enthalpy?
A+
BD
C+ B+D
Дн.
O A. AH = AH 2 - AHA
B. AH = AH-AHO 2
C. AHO = AH , + 2A HP 2
O D. AHO AHO, +AH2

explanation:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

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
