Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

10-12 C2/Nm2 8.988 x 109 Nm2/C2 Consider three identical metal spheres‚ A‚ B‚ and C. Sphere A carries a charge of 2.0 µC; sphere B carries a charge of -6.0 µC; and sphere C is neutral. Spheres A and B are touched together and then separated. Spheres B and C are then touched and separated. What will be the new net charge of sphere C? A. -6.0 µC B. -2.0 µC C. 0 D. -1.0 µC E. +4.0 µC Charges Q1 = q and Q2 = +9q are placed as shown below. Of the five positions indicated by the numbered dots‚ at which

The polymerase chain reaction (PCR) is a biochemical technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude‚ generating thousands to millions of copies of a particular DNA sequence. Developed in 1983 by Kary Mullis‚[1][2] PCR is now a common and often indispensable technique used in medical and biological research labs for a variety of applications.[3][4] These include DNA cloning for sequencing‚ DNA-based phylogeny‚ or

conductive paper. The electrical potential was measured from three different points for each positive charge and negative one. Introduction The objective of this research performed is to explore the relationship between electrical field strength and the distance from the charge. This research should fulfill Gauss’s law‚ which also known as Gauss’s flux theorem‚ is a law relating the distribution of electric charge to the resulting electric field. The law was formulated by Carl Friedrich Gauss in 1835‚ but

of points‚ charges are accumulated at the pointed ends of the comb‚ the field increases and ionizes the air near them. The positive charges in air are repelled and get deposited on the belt due to corona discharge. The charges are carried by the belt upwards as it moves. When the positively charged portion of the belt comes in front of the brush B2‚ by the same process of action of points and corona discharge occurs and the metal sphere acquires positive charges. The positive charges are uniformly

chargemaster‚ sometimes referred to as the charge description master or CDM‚ translates the clinical activities described in patients’ medical records into the language payers use to process claims. The CDM assigns a hospital-defined billing number to each billable service‚ supply‚ or pharmaceutical‚ and the billing number is then linked to a standardized numeric code used for submitting claims to insurers. The CDM number is also linked with a specific charge (price) for each service‚ supply‚ etc. being

In a ’demat account’ ‚shares and securities are held electronically instead of the investor taking physical possession of certificates. A demat account is opened by the investor while registering with an investment broker (or sub-broker). The demat account number is quoted for all transactions to enable electronic settlements of trades to take place. Every shareholder will have a demat account for the purpose of transacting shares. Access to the demat account requires an internet password and a

conversion from leasing off-site mainframe time to doing all computing in-house. That mission was to provide a network and platform that was “as reliable as a public utility.” In order for the CS group to maintain such a reliable system‚ they were in charge of purchasing and supporting all hardware and software and ensuring compatibility within the network. However‚ as computing needs changed‚ researchers demanded new and different hardware and software to allow them to better do their jobs. CS had

formula for an ion‚ its net charge is written in superscript immediately after the chemical structure for the molecule/atom. The net charge is written with the magnitude before the sign; that is‚ a doubly charged cation is indicated as 2+ instead of +2. However‚ the magnitude of the charge is omitted for singly charged molecules/atoms; for example‚ the sodium cation is indicated as Na+ and not Na1+. An alternative (and acceptable) way of showing a molecule/atom with multiple charges is by drawing out the

It consists of two sheets of conductor separated by a layer of insulator called dielectric. The capacitance of a capacitor is defined as the charge stored per unit potential difference applied to the capacitor : In the experiment‚ a reed switch allows the capacitor to be charged up and discharged rapidly :
