As a chemist for an agricultural products company, you have just developed a new herbicide,"herbigon," that you think has the potential to kill weeds effectively. a sparingly soluble salt, herbigon is dissolved in 1 m acetic acid for technical reasons having to do with its production. you have determined that the solubility product ksp of herbigon is 9.50×10−6. although the formula of this new chemical is a trade secret, it can be revealed that the formula for herbigon is x-acetate (xch3coo, where "x" represents the top-secret cation of the salt). it is this cation that kills weeds. since it is critical to have herbigon dissolved (it won't kill weeds as a suspension), you are working on adjusting the ph so herbigon will be soluble at the concentration needed to kill weeds. what ph must the solution have to yield a solution in which the concentration of x+ is 4.50×10−3 m ? the pka of acetic acid is 4.76.

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
