Name: Keziah V. Cuyom Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if

Chapter 2: Linear Functions Chapter one was a window that gave us a peek into the entire course. Our goal was to understand the basic structure of functions and function notation‚ the toolkit functions‚ domain and range‚ how to recognize and understand composition and transformations of functions and how to understand and utilize inverse functions. With these basic components in hand we will further research the specific details and intricacies of each type of function in our toolkit and use

What is the DuPont equation‚ and how does it capture the nature of expense control‚ efficiency of asset management‚ and financial leverage (or debt) of a firm? If you were the CFO of your firm (or a hypothetical firm)‚ what variable would you concentrate your efforts on and why? The DuPont equation is a method of measurement that was started by the DuPont Corporation in the 1920s. In this method of measurement the assets are measured at their gross book value rather than at their net book value which

Visual Perception Pictorial depth cues are what we use to create depth and distance on a 2D canvas or paper. Linear perspective is used when two parallel lines converge together and are perceived to come to a point into the distance. We perceive this in straight roads‚ railway tracks or hallways. This image displays linear perspective on the left side on the box as it is perceived to come together despite the fact that the lines are parallel. Interposition is used when an object sits in front

Scranton Engineers Club. This formula is given as Where σp is pillar strength‚ σ1 is uniaxial compressive strength of a cubical specimen (w/h = 1)‚ and w and h are pillar dimensions. According to Obert and Duvall‚ this equation is valid for w/h ratios of 0.25 to 4.0‚ assuming gravity-loading conditions. Through back calculations from mining case histories and utilization of laboratory rock properties‚ safety factors of 2 to 4 were derived for short- and long-term pillar
