DESIGN LAB Factors Affecting the Solubility of a Solid in a Liquid In this experiment‚ my goal is to determine the affect of temperature in the solubility of a solid in a liquid. Research Question: How does the change in the temperature affects the solubility of a solid in a liquid? Independent variables: Temperature of the Solution Dependent variables: The solubility of the solid substance Controlled Variables: * The pressure of the room. * The mass of zinc chloride

of natural resources like oil and gas are unevenly distributed across the world (Stutz‚ 2007). This essay will explain where the majority of oil and gas is located. Thereafter‚ the focus will be on the benefits and drawbacks of countries that are dependent on oil/gas. Finally‚ a conclusion will be given which sums up the most important factors. Allocation Oil/Gas The majority of the oil reserves are located in the Middle East. An estimate of 65% of the total worldwide reserves is situated in this

Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance

enzymes is the ability of the enzyme to catalyze thousands of reactions. Enzymes do not get used up during the reaction and can keep catalyzing reactions till there are no more substrates. However enzymes are tertiary proteins structures and are very dependent on the environment in which they reside in. Many factors such as pH‚ temperature‚ and salinity can affect the shape of the active site on the enzyme and decrease the rate of the reaction. Many tertiary proteins such as enzymes depend on various weak

Philippines becoming an independent country‚ after being occupied by three colonialists‚ was nothing but a victory and a moment of opportunity. Dr. Estanislao last August 21 had imparted his knowledge about how the country was fairing in terms of economic performance after the country became independent until present. According to him‚ these periods can be divided into three parts namely the post war era (1946-1966)‚ Macros era (1966-1986) and the post-EDSA era (1986-2006). The post war era‚ was

Hypothesis: Experimenter thinks the order of the solutions according to their concentration is D‚A‚E‚C‚B‚ from smallest. And the water will pass through semipermeable tubing bag from low to high concentration to thin the concentration inside the bag. Osmosis is a diffusion of water particles and is one of the passive transport

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By
