Purpose The purpose of the experiment is to determine the percent yield of the precipitate; by performing double displacement reaction between solutions of two different compounds. Introduction First of all when making a solution of two different compounds; there will many variables that can be considered during the experiment. However‚ the variables are controlled variables. Controlled Variables ∙amount of water that will be dissolved with the compound (amount of water until the compound is

Testing for Cation and Anions OBJECTIVE: • Determine the presence of a cation or anion by a chemical reaction • Determine the cation and anion in an unknown solution All salt solutions have both positive (Cations) and negative (Anions) ions dissolved in it. In this experiment you will observe chemical reactions to determine the presence of specific anions and cations. Compare your observations with the reactions of the known solutions and the unknown solution to determine the ions present

Exceptions Exception is an abnormal condition that arises when executing a program. In the languages that do not support exception handling‚ errors must be checked and handled manually‚ usually through the use of error codes. In contrast‚ Java: 1) provides syntactic mechanisms to signal‚ detect and handle errors 2) ensures a clean separation between the code executed in the absence of errors and the code to handle various kinds of errors 3) brings run-time error management into object-oriented programming

Cations and Anions Reaction Introduction: This experiment seeks to explore different chemical reactions conducted in the lab. A cation is defined as positively charged ions‚ which are K+ and Pb2+ in this experiment‚ and an anion is termed as negatively charged ions‚ which are CrO4 2- and NO3 2-. The major objective of this lab experiment was to examine the reaction between cations and anions‚ as well as observing‚ and documenting the chemical reactions. We will be demonstrating the reaction between

start your own business as a sole proprietor‚ in a partnership‚ or you can start or a buy corporation. There are advantages and disadvantages to each. However‚ there are risks no matter which form you choose. Before you decide which form is for you‚ you need to evaluate all the alternatives carefully. The most basic form of ownership is the sole proprietorship‚ a business own and managed by one person. This kind of business is easier of starting and ending‚ you also get to be your own boss; you get to
