Chemical Reaction of copper compounds Introduction: In this experiment‚ the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step‚ the solid copper is the limiting reactant

EXPERIMENT 6 – Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical

AQA GCSE Chemistry Unit 1 C 1: Fundamental ideas: C 1.1. Atoms‚ elements and compounds: * All substances are made up of atoms. * Elements contain only one atom. * Compounds contain more than one atom. * An atom has a tiny nucleus in its centre‚ surrounded by electrons. C 1.2. Atomic structure: * Atoms are made up of protons‚ neutrons and electrons. * Protons and electrons have equal and opposite electrical charges. Protons are positively charged‚ and electrons are negatively

Experiment 6 titled “Organic Chemistry” and the purpose of this lab is to get familiar with some organic functional group and test certain reactions of selected functional groups. To do the first part of the experiment (combustion test)‚ instructor demonstration in hood‚ and record the observation. Part A (combustion of toluene) pour 1 milliliter of toluene into a evaporating dish and ignite it with a flaming wood splint. Most importantly put the flame with a watchglass. Part B (combustion of ethyl

A successful crime investigation depends upon the collection and analysis of various kinds of evidence. Forensic scientists classify evidence in different ways and have specific ways of dealing with it. One major distinction is between physical and biological evidence. Physical evidence refers to any item that comes from a nonliving origin‚ while biological evidence always originates from a living being. The most important kinds of physical evidence are fingerprints‚ tire marks‚ footprints‚ fibers

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the

this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons. We used the sciatic Lithobates pipiens nerve in this

Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns
