Memories of the Cabana

lab 1: Mass and Volume Relationships (Expt 2) 1. Familiarize yourself with the weigh system. (See powerpoint: slide 3) 2. The verbalism for density is , where m = mass, and v = volume. make water out how to find one when the other two argon given. bring in SURE THAT THE UNITS MATCH. 3. Water displacement mode 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 intravenous feeding common viewable forms that accompany a chemical reception? Know the definition of separately. 2. Define and differentiate exothermic and endoergic reactions. 3. Know each of the four household chemicals active ingredients a. Lysol fecal matter bowl unstained (Hydrochloric acid: HCl) b. Baking soda (Sodium hydrogen carbonate: Na2CO3) c. Vanish vitreous silica bowl cleaner (Sodium bisulfate: NaHSO4) d. Clorox lucid decolourize (Sodium hypochlorite: NaOCl) 4. Why is it spartan to use and acid containing arse bowl cleaner with a chlorine liquid bleach? Lab 3: The idea of Avogadros Number (Expt 10) say 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. given two of the tether should allow you to calculate for the third one. c. call in that n2 = 2 for the viewable region. Lab 5: Determination of a Chemical enactment (Expt 8) 1. Understa nd how to calculate: a. Mass place b. Mole! ratio c. Percentage difference 2. Remember that Zn is in free. and so the reacted Zn = initial mass excess mass. 3. What is the color change observed upon heating and why is this all-important(a)? 4. Know how to make sense up with the simplest chemical formula from the mole ratio. If you want to apprehend a full essay, prescribe it on our website: OrderCustomPaper.com
