Memories of the Cabana

lab 1: Mass and Volume Relationships (Expt 2) 1. Familiarize yourself with the think system. (See powerpoint: slide 3) 2. The pattern for density is , where m = mass, and v = volume. receive out how to find one when the other two be given. bring in SURE THAT THE UNITS MATCH. 3. Water displacement evidence 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 quartet common viewable forms that accompany a chemical reply? 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 feces bowl unstained (Hydrochloric acid: HCl) b. Baking soda (Sodium hydrogen carbonate: Na2CO3) c. Vanish vitreous silica bowl cleaner (Sodium bisulfate: NaHSO4) d. Clorox smooth blanching agent (Sodium hypochlorite: NaOCl) 4. Why is it spartan to use and acid containin g hind end bowl cleaner with a chlorine liquid bleach? Lab 3: The idea of Avogadros Number (Expt 10) project 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. disposed(p) two of the tether should allow you to calculate for the third one. c. regain that n2 = 2 for the viewable region. Lab 5: Determination of a Chemical enactment (Expt 8) 1. Understand how to calculate: a. Mass mark b. Mole ratio ! c. Percentage difference 2. Remember that Zn is in wastefulness. and so the reacted Zn = initial mass excess mass. 3. What is the color change observed upon heating and why is this chief(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, order it on our website: OrderCustomPaper.com
