The equivalence point occurs when [h+] = [oh-]. true false

-

True

Explanation: -

The equivalence point in a titration is the point when both the acid and base have been completely consumed.

Total amount of acid present = [H⁺ ]

Total amount of base present = [OH⁻ ]

Thus at equivalence point,

total amount of base should be equal to total amount of acid.

[H⁺] = [OH⁻]

whats the meaning of /

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
