1. you start with 0.020 l of 0.050 m benzoic acid (ka = 6.28*10-5).
a) what is the initial ph?
b) what is the ph if you add 5.0 ml of 0.0010 m koh?
c) how much volume of the 0.0010 m koh would you need to add to get to the equivalence point?
d) what is the ph at the equivalence point?
e) after the addition of 25 ml of 0.050 m koh, what is the ph?
f) how much volume of the 0.050 m koh would you need to add to get to the equivalence point? 9) [what type of indicator would you choose to follow this titration? what change do you expect to see at the equivalence point? ] h) (sketch a curve of volume of 0.050 m koh added to ph and mark the different points of interest. at what volumes of koh added do you have a buffer solution? ]

Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material
