bleaching in lives. PPT 2 Here is what we are going to talk about in the next 5 minutes. How do manufacturers bleach something into light colors? How do things in white are easily to get yellow? Why do they do so? The reason of getting yellow. The solution to the problem. Difference between sulfide bleach and chlorine bleach. PPT 3 We heard words such as “bleach for unbleachables” from TV commercials. But what exactly is bleaching? Does it mean making things turn into a lighter

What exactly are they? They are ways for companies to catch the attention of consumers to entice us to purchase or use their products. My advertisement is an internet ad for Clorox Bleach. As I was researching different ads for this particular product something caught my eye. It seemed that every ad for Clorox bleach had a woman‚ and a reference to domestic duties of cleaning in some form. I will give my analogy of the two ads I found interesting. Both are from different eras‚ but seemed to be alike

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Investigation – Storage conditions of Bleach & it’s relation with temperature. Title/Research Question: ‘How does temperature effect the concentration of chlorate ions in bleach?’ Aim: The aim of this experiment was to investigate the optimum temperature storage conditions of bleach’s stored at different temperatures. Introduction: Chlorine bleaches are made by dissolving chlorine in sodium hydroxide solution. They have a number of uses as they are used to remove colors‚ whiten or disinfectant

What is commercial arable farming? Commercial arable farming is a system of farming carried out on a very large scale‚ it is the extensive cultivation of usually one crop for sale in order for large profits (Monoculture). Some examples of crops that are associated with commercial arable farming are tobacco in Cuba‚ sugarcane in Barbados and Cotton in India. GUYANA‚ a Caribbean territory located between Venezuela and Suriname in South America practices arable farming on a large scale. Their crop/product

A comparative study between bleach and kalamansi (Citrofortunella microcarpa) in removing stain. Introduction: Calamondin or Kalamansi is a fruit tree in the family Rutaceae and a member of citrofortunella that was developed in and is very popular throughout Southeast Asia‚ Especially the Philippines‚ where it is most commonly used for cooking. It is a shrub or small tree growing to 3-6 m‚ and bears small citrus fruit used to flavor foods and drinks. It also gives people extra income

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Introduction: The purpose of this lab was to take a variety of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal
