Every solution has either has an acid or basic trait. The acid or basic trait in a solution are called pH level. pH is a scale that is used to determine if solution is acidic ‚basic‚ or neutral. During Living Environment class‚ we conducted a experiment that allowed us to measure the pH levels of 3 solutions. We were split into groups and each person had to bring a household solution from around the house. There certain materials that were needed to conduct the experiment .The following

What are the advantages and limitations of Relational Database Model? Advantages: he relational database model was first introduced by E.F. Codd of IBM in 1969. In the relational model‚ data are structured into tables (i.e.‚ "relations") consisting of rows and columns. Each row contains a single record comprised of individual data elements (or "attributes") organized in columns containing elements of the same kind according to the rules defined for that column. Alternate database models include

Case study: MTN Introduction: The resource-based view of strategy According to Segal-Horn (2004 p 163) the Resource-Based View (RBV): “ ... places the firm rather than the industry at the centre of strategy formulation ... It has an internal resource focus rather than an external industry or market focus for strategic thinking.“ Why RBV? Rumelt’s research (Unit 3 Section 2 pp 8-9)‚ although contested‚ showed that the industry environment accounted for a very small percentage of the

DATABASE MANAGEMENT SYSTEM (DBMS) A Database Management System (DBMS) is a software program that typically operates on a database server or mainframe system to manage structured data‚ accept queries from users‚ and respond to those queries. A typical DBMS has the following features (Stair and Reynolds‚ 2004): Provides a way to structure data as records‚ tables‚ or objects Accepts data input from operators and stores that data for later retrieval Provides query languages for searching‚ sorting

person can fall sick and it might be harm to the person. The maintenance of blood pH is called acid-base homeostasis. Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells. BACKGROUND A substance that has high concentration of hydrogen ion in solution is called acid and solution that has low concentration of hydrogen ion is base. Base

experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble and are harsh tasting compounds
