Calculate the pH of a solution containing:
a) 0.0500 M methanoic acid and 0.100 M sodium
methanoate. (K, =1.6 x 10-4 mol dm-3)
b) 0.0100 M benzoic acid and 0.0400 M sodium
benzoate (Ka = 6.3 x 10-5 mol dm-3).
c) 0.100 M ethanoic acid and 0.200 M sodium
ethanoate (pK, ethanoic acid = 4.8)​

b. examine and describe cells

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

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.
