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.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

cock topography

the study of the surface of a large voluptuous cock.

look at that sorostitute right she's a cock topographer!

what classes are you taking this

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
