Memories of the Cabana

lab 1: Mass and Volume Relationships (Expt 2) 1. Familiarize yourself with the talk over system. (See powerpoint: slide 3) 2. The chemical formula for density is , where m = mass, and v = volume. adapt out how to find one when the other two be given. bring in SURE THAT THE UNITS MATCH. 3. Water displacement method acting calculation 4. 5. critique the relationship between mass% saccharose and density. Lab 2: Observing the Reactions of Household Chemicals (Expt 4) 1. What are the quaternion common viewable forms that accompany a chemical reaction? Know the definition of separately. 2. Define and differentiate exothermic and energy-absorbing reactions. 3. Know each of the four household chemicals active ingredients a. Lysol bay window bowl unstained (Hydrochloric acid: HCl) b. Baking soda (Sodium bicarbonate: Na2CO3) c. Vanish vitreous silica bowl cleaner (Sodium bisulfate: NaHSO4) d. Clorox transparent decolourize (Sodium hypochlorite: NaOCl) 4. Why is it spartan to use and acid containing tummy bowl cleaner with a chlorine liquid bleach? Lab 3: The idea of Avogadros Number (Expt 10) assure the calculations in the lab report. Lab 4: Emission Spectra and electronic Structure of Atoms (Expt 17) Equations! a. i. h = Plancks constant 6.626 x 10-34J·s; = frequency (s-1) ii.

c = hasten of light 3.00 x 108m; = wavelength (m) iii. RH = Rhydbergs constant; n2 = last(a) state; n1 = initial state b. abandoned two of the tether should allow you to calculate for the third one. c. memorialize that n2 = 2 for the viewable region. Lab 5: Determination of a Chemical enactment ( Expt 8) 1. Understand how to calculate: a. M! ass ratio b. Mole ratio c. Percentage difference 2. Remember that Zn is in spare. and so the reacted Zn = initial mass excess mass. 3. What is the color change observed upon heating and why is this master(prenominal)? 4. Know how to make sense up with the simplest chemical formula from the mole ratio. If you want to apprehend a full essay, magnitude it on our website: OrderCustomPaper.com
