electrical control panels. Material or equipment stored in front of the panels would slow down the shutting down of power in an emergency situation. 6. Use and store chemicals safely. Read the label and the Material Safety Data Sheet to determine flammability and other fire hazards. Provide adequate ventilation when using and storing these substances. 7. Use all precautions to prevent ignition in potentially explosive atmospheres such as those containing flammable liquid vapors or fine particles. Use

explosion (Saisantosh et al., 2017). This subsequently ignites the gasoline from all directions (For example, putting fuel on a fire), instead of just a spark in one end of the combustion cylinder. Hydrogen behaves like this because it has a very wide flammability range-from 4% to 75% in air (Duncan, 2017) . Due to this there is a release of energy in a short period of time, causing the mixture to get hot and greatly expand in volume (Saisantosh et al., 2017). If the fuel is not fully burnt in that short

removing by hand, and fractional distillation to achieve this. Once we had all the pure substances we began testing their characteristic properties. We used several characteristic properties to identify the pure substances. For the liquids we tested flammability, density, and boiling point. For the solids we tested solubility in water and density. These were useful in identifying pure substances because by looking at what we learned from them, along with the color, odor, and transparency of the substance

Bed Bath and Beyond is struggling in the current market. This PEST analysis is aimed at determining what the major Political, Economic, Social, and Technological are in current business environment, and how these factors are affecting the Home Goods Retail industry. The modern polarized political sphere, especially in the United States, can mean that elections result in a massive change in policy, especially regulatory reforms on businesses. With an increasingly global and fluctuating economy, modern

Side #3 – Physical & Chemical Properties  Include five pieces of information that is appropriate to your element eg ◦ Colour: ◦ State of matter at room temperature: ◦ Density: ◦ Melting point: ◦ Boiling point: ◦ Odour / Texture / Hardness: ◦ Flammability: ◦ How reactive is it? (Will it combine with other elements?) Side #4 – Periodic Table Information:  Include the following five pieces of information that is appropriate to your element: ◦ Type of Element: ◦ Atomic Number: ◦ Atomic Mass: ◦ Period

is a physical property because there is no new substance being created. b) Propane, leaking from a damaged tank, igniting easily is a chemical property because the propane changes into new substances when it undergoes this chemical reaction. Flammability describes the behaviour of a material when it is chemically changed,. c) Silver jewellery tarnishing in the air is a chemical property because the silver is reacting with the air, changing the silver

combustion often require close collaboration between several fields of scientific expertise (macromolecular and physical chemistry, physics of mass and heat transfer, rheology, etc.). Fire retardants are combined with polymer resins to reduce their flammability, decrease production of volatiles and inhibit

How can one human mind organize and memorize over 100 elements? In 1869, Dmitri Mendeleev, a Russian chemist and inventor, was credited with creating and publishing the Periodic table. The Periodic table is an arrangement of the chemical elements discovered on earth. These elements are organized by their atomic number and similarities between chemical properties. The Periodic table holds 118 elements which can be broken down into smaller classifications, groups (vertical), periods (horizontal) and

lighting. Coal gas is a combination of hydrogen (a chemical substance that is highly flammable), methane (a natural gas, used now for lighting and fuel) and carbon monoxide (a light gas with air density); which because of their properties and flammability, very useful for lighting. As a result of this invention, all workers (even peasants) could get the light that they needed in order to keep up with the high work demand around the clock, since one light could last for 24 hours. Another thing
