The Chemistry of Toothpaste Toothpaste is not a new thing. It has been traced back to Ancient Egypt. They used a powdered rock and vinegar‚ which created a chemical reaction that dissolves the plaque on teeth. In 1900’s people used hydrogen peroxide and baking soda or chalk‚ pulverised brisk and salt as a toothpaste. Toothpastes today‚ are mostly made up of abrasives‚ surfactants‚ a detergent‚ a thickener‚ a moisturizer‚ water‚ flavouring agents‚ coloring‚ sweeteners‚ fluoride and desensitizers

Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial

The chemistry of hairspray What is hairspray: introduction Hair spray (or hair lacquer) is a common household aqueous solution that is used to keep hair stiff or in a certain style. Weaker than hair gel‚ hair wax‚ or glue‚ it is sprayed to hold styles for a short period of time. Using a pump or aerosol spray nozzle it sprays evenly over the hair. Hairspray was first developed and manufactured in 1948 by Chase Products Company‚ based in Broadview‚ Illinois.Its active ingredient is a suitable

above and their stipulated current flaws‚ we think that the Indianapolis 500 marketing team should focus most of their efforts within the social media world. We also believe that the Indianapolis 500 should put on a concert and other events that would help attract people that aren’t necessarily racing fans. These concerts and events will attract attention on social media as well. Social media is such a connecting part of life for so many people in today’s society. We think this strategy could reach

If the minimum wage increases‚ it doesn’t necessarily mean that the economy will get better or our standards of living will be better. If wages go up‚ then the cost of living will also increase. Some statistics have proven why the rise of the minimum wage will cause more issues. As the minimum wage increases‚ the unemployment rate will increase. As well‚ there is an enormous potential of causing small business to collapse due to higher salaries and the inability to afford them. Machines would replace
