vinegar the IC

45 From noon until three in the afternoon darkness came over all the land. 46 About three in the afternoon Jesus cried out in a loud voice, “Eli, Eli,[a] lema sabachthani?” (which means “My God, my God, why have you forsaken me?”).[b]

47 When some of those standing there heard this, they said, “He’s calling Elijah.”

48 Immediately one of them ran and got a sponge. He filled it with wine vinegar, put it on a staff, and offered it to Jesus to drink. 49 The rest said, “Now leave him alone. Let’s see if Elijah comes to save him.”

50 And when Jesus had cried out again in a loud voice, he gave up his spirit.

51 At that moment the curtain of the temple was torn in two from top to bottom. The earth shook, the rocks split

A common symbol for acetic acid is AcOH (or HOAc), where Ac is the pseudoelement symbol representing the acetyl group CH3−C(=O)−; the conjugate base, acetate (CH3COO−), is thus represented as AcO−. Acetate is the ion resulting from loss of H+ from acetic acid. The name "acetate" can also refer to a salt containing this anion, or an ester of acetic acid. (The symbol Ac for the acetyl functional group is not to be confused with the symbol Ac for the element actinium; context prevents confusion among organic chemists). To better reflect its structure, acetic acid is often written as CH3−C(O)OH, CH3−C(=O)−OH, CH3COOH, and CH3CO2H. In the context of acid–base reactions, the abbreviation HAc is sometimes used, where Ac in this case is a symbol for acetate (rather than acetyl).

Specific enthalpy

The specific enthalpy of a uniform system is defined as h = H / m 

⁠ , where m is the mass of the system. 

E = m*C^2 ==> m = E/C^2

Its SI unit is joule per kilogram. It can be expressed in other specific quantities by h = u + p v , where u is the specific internal energy, p is the pressure, and v is specific volume, which is equal to ⁠
