Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

CMIS 320 Lab 1 Homework Part 1 a) A piano manufacturer wants to track all pianos it makes. Each piano has a unique serial number and a manufacturing completion date. Each instrument represents exactly one piano model‚ all of which have an identification number and model. The company produces thousands of pianos of a certain model‚ and the design is specified before any single piano exists. 1. Identify the degree and cardinalities of the relationship. Piano-Model: Cardinality: one-to-many

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

Regents Biology Period _________ Date ______________________ LAB ____. ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time. In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures

Lab 1 1. The white charge producer has a positive (+) polarity. The blue charge producer has a negative (-) polarity. 2. The positive charge builds significantly then remains as the charge producer is removed. 3. The negative charge builds significantly then remains as the charge producer is removed. 4. When the white charge producer is lowered then removed from the ice pail with out touching the positive charge builds then drops when the charger is removed. 5. When the ice pail
