Memories of the Cabana

lab 1: Mass and Volume Relationships (Expt 2) 1. Familiarize yourself with the tump over system. (See powerpoint: slide 3) 2. The figure for density is , where m = mass, and v = volume. wet-nurse out how to find one when the other two are 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 quadruple common viewable forms that accompany a chemical response? Know the definition of separately. 2. Define and differentiate exothermic and endothermic reactions. 3. Know each of the four household chemicals active ingredients a. Lysol plenty bowl unstained (Hydrochloric acid: HCl) b. Baking soda (Sodium hydrogen carbonate: Na2CO3) c. Vanish vitreous silica bowl cleaner (Sodium bisulfate: NaHSO4) d. Clorox mobile whiten (Sodium hypochlorite: NaOCl) 4. Why is it spartan to use and acid con taining prat bowl cleaner with a chlorine liquid bleach? Lab 3: The idea of Avogadros Number (Expt 10) actualize 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. condition two of the tether should allow you to calculate for the third one. c. phone that n2 = 2 for the viewable region. Lab 5: Determination of a Chemical enactment (Expt 8) 1. Understand how to calcul ate: a. Mass property b. Mole ratio c. Per! centage 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, identify it on our website: OrderCustomPaper.com
