Lab‚ Week # 1 BALANCE LAB Introduction The purpose of this lab is to learn how to utilize two different balances to find the mass of different chemicals in the ChemLab program. A balance is an instrument used to determine the mass of a chemical. To accomplish this we use direct weighing and weighing by difference on both the centigram and electronic balances. Equipment 1 Centigram Balances 1 Electronic Balance 1 100ml Beakers 5 Copper Slugs 2 Unknown Weights (Label # 1‚ # 2)

Period 12 Chemical Aspects of Life & Spit Lab ABSTRACT: The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence

Mariana Mendoza Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper

The barrels that exceeded 50ppt were 3‚ 10‚ 11‚ 13‚ 17‚ 18‚ 22‚ 24‚ 26‚ 30‚ 31‚ 39‚ 42‚ 45‚ 47‚ and 49 (Table 2b). This indicated that these barrels were above the regulated amount. During this same experiment‚ 26 barrels exceeded the 5% (50ppt) threshold. These were barrels 3‚ 4‚ 6‚ 8‚ 10‚ 11‚ 13‚ 17‚ 18‚ 20‚ 22‚ 24‚ 25‚ 26‚ 27‚ 30‚ 31‚ 34‚ 38‚ 39‚ 42‚ 44‚ 45‚ 47‚ 49‚ and 50 (Table 2a‚ Table 2b).

Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity
