Portfolio By Make-Up Artist Table of contents - Introduction - Information about the job field - Relevance - Sources Introduction We had the task to make a portfolio and an image video about our dream job or a job that we could see ourselves doing in the future. We decided to make a portfolio about the job as a make-up artist because we were really fascinated with this job field as we all personally like to experiment with make-up and hair and

Cloud Model - an atom is comprised of a nucleus made up of neutrons and protons‚ and electrons moving extremely fast around the nucleus‚ forming an electron cloud instead of moving in orbits like what Bohr’s model suggests - proposed by Erwin Schrodinger in 1926‚ when he derived this model using a mathematical equation that he himself made http://1.bp.blogspot.com/-LEqGPr4h8R4/TsgJyT6vP6I/AAAAAAAAAKE/pTl6O3V2u0M/s200/electron_cloud_model.jpg The Planetary/Bohr’s Model - an atom is comprised of

attention‚ drops their pennies on the floor and become rusty over time. The reason for this is the air and other things that come into contact with this penny. A cleaning solution can be described in chemical formula of Acetic acid‚ a colorless organic compound‚ which has a pH number of 2.4 and reacts with most metals‚ like iron. When making a dull penny clean‚ there are two chemical reactions involved in doing it. One chemical is white vinegar‚ which involves liquid being formed of about acetic acid

Within the context of drag entertainment it is obvious that make-up has a primary role in a drag artist’s consumption to create the character. Make-up within this context refers to theatrical make-up‚ i.e. make-up that is used to assist in creating the appearance of the characters that actors portray during a theater production‚ rather than cosmetics. Make-up is used to bring the character to fruition and therefore creates the illusory aspect of a drag artist’s performance: verisimilitude. Mariana

COrdination compounds Question 9.1: Explain the bonding in coordination compounds in terms of Werner’s postulates. =Werner’s postulates explain the bonding in coordination compounds as follows: (i) A metal exhibits two types of valencies namely‚ primary and secondary valencies. Primary valencies are satisfied by negative ions while secondary valencies are satisfied by both negative and neutral ions. (In modern terminology‚ the primary valency corresponds to the oxidation number of the metal

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance
