  • Crj101 chemistry short notes

    This PDF content is concise notes on chemical bonding, which is fundamental topic in chemistry. This handwritten notes have been uploaded for academic support. They will be highly beneficial for learning and revision and they are prepared at a good academic standard.

    Requirements:

  • Stoichiometry: Calculating how much product you’ll actually…

  • Balance the Equation: You can’t do stoichiometry without a balanced chemical equation.
  • Convert to Moles: If you are given grams, divide by the Molar Mass.
  • The Mole Ratio: Use the coefficients from the balanced equation to switch from your “known” substance to your “unknown.”
  • Convert to Final Units: Multiply by the molar mass of the new substance to get back to grams (or use $22.4 text{ L}$ for gases at STP).

    • Requirements:

  • Photocatalysis method to remove mercury II ions from wastewa…

    Requirements:

  • Assignment

    Document attached! Please let me know if you would be able to help with this assignment: what steps because it has to be explained on her end!

  • Melting Point Determination Lab Report

    The labs are intended to make you use the scientific method, to understand, and to reinforce

    concepts learned in class. If you need help, please ask.

    The lab reports must be typed or clearly written and the pages stapled together. Reports must be

    neat or they will not be accepted.

    Use passive language when writing a report; avoid using personal pronouns (I, We).

    o This 15.50 grams of solvent were added to the round-bottomed flask.

    o Not this We added 15.50 grams of solvent to the round-bottomed flask.

    Format for reports:

    Part I. Purpose

    one sentence stating the purpose of the experiment (why you are doing the experiment or

    what you are trying to determine or synthesize).

    Part II. Materials and Methods

    detailed list of chemicals and equipment used (ex. 1.0 M sulfuric acid, Buchner funnel)

    chemical structures of organic reagents used

    procedure you followed with enough detail that someone who only had your report could

    do the experiment

    Part III. Results

    chemical reaction equations if conducting a synthesis

    observations

    any measurements, data sheets, calculations, handouts, drawings, photos, etc.

    Part IV. Discussion

    -define new terms

    -discuss the theory behind the experiment; incorporate relevant terms and definitions

    -analyze or interpret your results

    -discuss your experimental results/calculations versus theoretical

    -discuss any mistakes or possible sources of error and their impact

    Part V. Conclusion

    summarize the experiment, outcome, and what it means in one paragraph

    Part VI. Answers to assigned questions from lab manual or instructor

    • Please answer the three questions at the end of the report separately.
