wash each of these‚ we adopt a sort of middle-of-the-road approach—spray some stain remover on it before throwing it in; maybe pour in some fabric softener; wash it in warm water (Americans seem to be allergic to hot-water washing); rely on the detergent to have a lot of bleaches‚ color brighteners‚ and whiteners; give it a cold rinse; and hope for the best. Unfortunately‚ that "best‚" compared to clothes washed in European machines‚ is noticeably inferior. Why? Whereas Americans use top-loading

create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a visual display of the reaction. After 10 seconds the volume of foam was measured‚ recorded and tabulated‚ and was then used to find the rate of the reaction. The hypothesis was supported by the results‚ showing that an increase

The Relation of Antiseptics and Bacteria Growth Purpose: To explore the effectiveness of different levels of concentration of antiseptic and antibacterial products’ prevention of bacterial growth. Question: Amongst common household products‚ which antiseptic and level of concentration is more effective at inhibiting the growth of bacteria? Introduction: Antiseptics are antimicrobial substances used on living tissue to reduce the possibility of infection‚ putrefaction or sepsis. The word “anti”

Environmental Pollution There are three main branches how we are destroying our environment the air pollution‚ water pollution and soil contamination. I chose this topic because I find it very important because it affects our environment‚ and not only that‚ indeed‚ we affect it and the consequences that could arise destroy our home planet. In this essay I will talk about environmental pollution‚ the reason for environmental pollution‚ its consequences and possible solutions. Trying to

Get a dripper bottle of detergent and transfer 9 ml of hydrogen peroxide from the beaker using a dropper and place the amount in a small measuring tube. Put two equal drops (as close to equal as possible) of detergent along with the 9ml of hydrogen peroxide in the small measuring tube in each measuring

o Used as a flux gas which lowers the melting point of the silicon dioxide and the calcium carbonate - Soap and detergents o Used as a base in soap and detergents. It is also used to make sodium phosphate and sodium silicate that act as builders - Softening hard water o The carbonate ions precipitate calcium and magnesium ions‚ this is why it is used in some soaps and detergents - Baking soda production o Sodium hydrogen carbonate or bicarbonate of soda is produced as a part of the process

The gritty feeling of toothpastes is the abrasives. They help get rid of plaque‚ stains‚ and polishing teeth. Today the most common abrasives are made up of hydrated silica‚ aluminium oxides‚ and calcium carbonate. Different phosphates of calcium or aluminium can be also used‚ but are less common. Detergents‚ like abrasives‚ also

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the
