2. (part ii) step 8 - calculate the dissociation constant of acetic acid. a. record the ph. b. determine the acetate ion concentration, [a- ], at equilibrium. c. determine the acetic acid concentration, [ha], at equilibrium. d. determine the experimental value of ka of acetic acid. e. show your calculation of [h+ ] from the ph and calculation of the ka value. 3. (part ii) step 9 repeat the calculations above (2a-e) using the data from step 9. 4. (part ii) step 10 repeat the calculations above (2a-e) using the data from step 10.

is there multiple choice answers?

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
