A solution prepared by mixing NaOH with NaHCO3 was diluted to 500 mL with water. A 25.00 mL aliquot was titrated with 0.1202 M HCI. The buret read 14.37 mL at the Ph endpoint and 38.52 mL at the MR endpoint. What were the concentrations of the substances in the 500-mL solution? Clue: what happens when NaOH and NHCO3 are combined? What species are present after the mixing? From the volume of HCI used up for the Ph and MR endpoints, what can be deduced?

Hello can you please help me answer this?
Based on the chemistry in this experiment, complete the following reaction.
Polarity and Solubility Predictions Directions: Show your molecule below. Circle or highlight all polar portions of the how molecule. Make a reasonable prediction about whether your molecule will be soluble in water or not and explain your reasoning. If your molecule seems to be borderline in polarity, making it difficult to predict solubility, explain your reasoning and the difficulty involved. Find a source (Merck Index, PDR, etc.) that discusses the water-solubility of your drug. Compare your predictions with the information you find on the water-solubility of your drug and comment on any discrepancies. Calculate how vol) solution of mL of

5. Suppose you have a mixture of water and your 2-chloro-2-methylbutane product in a separatory funnel. Use densities to predict which phase will be the top layer in the funnel. a. 2-chloro-2-methylbutane (organic phase) b. water (aqueous phase) c. there would only be one phase since the substances are miscible
The dissolved coffee in hot water can be separated by which technique? a. using a magnet b. evaporating the water c. filtering the solution d. decanting the solution
1. Did the slime pick up water soluble or water insoluble inks in? From these results, what can you conclude about the polarity of slime molecules? Explain. 2. Explain how you determined your hypothesis about whether or not the slime would pick up water soluble inks. What scientific information did you incorporate to formulate the hypothesis? Was your hypothesis correct?
Directions: A list of organic compounds is given on the 1st column. Check the boxes of qualitative test of which you think the compound will give a POSITIVE RESULT.
1. What are fibers and where are they found? How could forensic scientists use fibers to solve a crime? 2. Define the word probative. What is the probative value of a fiber in a forensic investigation? 3. Describe steps you would take from collecting a fiber(s) at a crime scene to performing an analysis to determine its identity. 4. Which of the 6 fiber types you observed are natural? Which are man-made? 5. Are fibers classified or individualized? Why?
