Assume you have a species X- that is oxidized with S2O82- according to reaction (1). Like you did in lab, you will add thiosulfate to "quench" the product until a specific concentration is produced (reaction 2). Once the thiosulfate is gone, the product will react with Z (aq) to produce a green colored complex. Reactants were added according to the table below. Each mixture contained 15.0 mL of the 0.0015 M Na2S2O3 solution and 3 drops of the 2% Z solution. Lastly, sufficient volumes of the counterion salt solutions were added for a total volume of 90.0 mL. The temperature was 25 °C, and the measured time is shown below.
Mixture # 0.300 M 0.150 M Δt to green [X⁻ ]i (M) [X3-]t(M/s)
NaX (mL) (NH4)2S2O8 (mL) (s)
1 30.0 30.0 41.0
2 15.0 30.0 162.0
Complete the table above.
Determine the order of the reaction with respect to X-.

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?

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

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
