• Jan 01, 2017 · This worksheet will help learners understand the basics of the reactivity series; answers have been included to aid students study.
  • Jul 29, 2002 · In laboratory exercise 4 you investigate five enzymes: catalase, amylase, lipase, pepsin, and trypsin. As an enzyme works it combines with its substrate and converts it to product(s). You will monitor the activity of the enzymes by observing changes in the amounts of substrate and products.
  • What is the activity series of metals? Metals have different chemical reactivities. The activity series of metals is the arrangement of metals in order of chemical reactivity from most to least active. Most active metals. Magnesium Zinc Iron Lead----- Metals above this line can displace hydrogen from acids. Copper Silver Gold. Least active metals
  • Geology Laboratory: Mineral Properties Revised on 8/27/2012 Page 2 of 13 The precise chemical composition and internal atomic that defines estructure ach mineral also directly determines its outward appearance and physical properties. Thus, in most cases, general appearance and a few physical easily determined
  • Quiz questions involve your ability to understand the purpose and predictive nature of an activity series. Quiz & Worksheet Goals In these assessments you'll be tested on the following concepts:
  • Base your answers to questions 66 through 68 on the information below. In a laboratory, a glass tube is filled with hydrogen gas at a very low pressure. When a scientist applies a high voltage between metal electrodes in the tube, light is emitted. The scientist analyzes the light with a spectroscope and observes four distinct spectral lines.
  • Chemical properties are those properties that change the composition of an element or compound. Examples of chemical properties could include heat caused by combustion, a chemical’s reaction with water, or the pH of an element. Below are some example elements and compounds and their chemical properties. H 2 O
  • Nov 07, 2016 · If a reaction is observed, we can use our knowledge of the chemical species involved to figure out the chemical reaction. Step 2. Action: Create several half-cells, each consisting of a metal strip (an electrode) dipped in solution of that metal’s salt (an electrode solution). Combine various half-cells into pairs (galvanic cells) and try ...

Laboratory workers, and all BSU employees, should consult this guide before allowing or undertaking drain disposal of any lab chemicals. Adherence to this guidance will be evaluated during laboratory and facility inspections conducted by the BSU EHS Office as recommended by the BSU Chemical Hygiene Plan. 3.0 GENERAL SEWER DISPOSAL GUIDELINES
Consequently, molecules of water join together transiently in a hydrogen-bonded lattice. Hydrogen bonds have only about 1/20 the strength of a covalent bond, yet even this force is sufficient to affect the structure of water, producing many of its unique properties, such as high surface tension, specific heat, and heat of vaporization.

Answers to the worksheet 1. The periodic table is defined as an organization of the elements in order of increasing atomic number and grouped according to similar chemical properties and similar electron arrangements. 2. Elements are substances that cannot be broken down into simpler stuff by any chemical means. 3.
mark no answer or more than one answer are counted as incorrect. Nothing is subtracted from a score if you answer a question incorrectly. Therefore, to maximize your score it is better for you to guess at an answer than not to respond at all. • Record all answers on your answer sheet. Answers recorded in your test book will not be counted.
