If age 18 is legally considered an adult‚ why can’t they drink alcohol? In 1984 the drinking law was changed from 18 to 21(Procon.org)‚ since then there has been a 13% rise in car accidents due to under age drinking ‚ 300 deaths and 2‚100 homicides per year due to under age drinking. Therefore I believe the age to consume alcohol should be lowered to a younger age. At age 18 you are legally considered an adult‚ you are able to join the military‚ get married and even start taking classes to run

Does technology make us dependent ? The old saying goes "too much of a good thing…" (cato) Technology has spread extravagantly over the course of the past 10 years . Before that ‚ there was no wireless ‚ personal computers ‚ mobile phones‚ iphones . Technology has become so integrated into people ’s daily lives that it has made them dependent. They are no longer able to live happily ‚ do tasks efficiently or communicate with each other ‚ or even think for themselves without it . -Supporters

Experiment # 4: Analysis of Soda Ash Experiment # 5: Volumetric Analysis of a Carbonate – Bicarbonate Mixture Submitted by: Eugenio December 2012 Department of Chemical Engineering University of Santo Tomas España‚ Manila Abstract Soda ash is the common name for sodium carbonate (NaCO3)‚ a chemical salt derived from carbonic acid. It is frequently used in manufacturing‚ industry‚ and in domestic chores. Glass production is one of the primary industrial uses for sodium carbonate. It is also

The problem is the people question why the drinking age is 21 and not 18 when can you buy tabaco legally at the age of 18 and you can’t buy alcohol at 18 too. I believe the drinking age should be 21 because teen’s brains are not done growing at the age of 18 and they could be damaged. My first reason is that when the law was moved to 21 the drunk driving dropped. My second reason is that when teens start drinking at such a young age they can have several health problems when they get older so by

Aim To find out the difference of reaction time it takes for the baking soda when it meets the vinegar under the condition that the volume of the vinegar changes. Background Information The two reactants‚ which are baking soda and vinegar‚ react with each other. Then it creates product‚ carbon dioxide‚ water and sodium acetate. The chemical name of vinegar is ethanoic acid and baking soda is sodium hydrogen carbonate. To illustrate this phenomenon as a chemical equation‚ it can be shown as C_2 H_4

nonetheless. Soda has similar effects only consumed for different reasons. Soda was tested on rats and the results projected‚ that soda has the effect of vasodilation: lowering the blood pressure‚ for a few reasons‚ main one SO2 suppresses certain catecholamine’s (Institute‚ 2007). This shows that the initial effect would be suppressing the blood vessels leading to a higher blood pressure. Caffeinated soda had similar effects when consumed‚ vasodilation occurs (Experimental‚ 2010). Just soda alone has

Alcohol has been a part of people’s life for a very long time. Even though the consumption of alcohol has a long history‚ the law regarding drinking age has changed over years. The debate over the drinking age in the U.S. is still causing stir. Nowadays a person who is 21 or older can legally purchase alcohol beverages. This policy attempts to protect younger people from making wrong decisions and abusing alcohol. Not everyone agrees with this theory and I’m one of these people. In my opinion young

All sites must be listed after each question. Why does mixing Mentos with soda produce this incredible eruption? Explain the SCIENCE behind it! Mixing mentos and soda produces this incredible eruption because of something called nucleation. The mentos are attracted to the Carbon Dioxide in the soda. After the mentos create so much pressure in the bottle‚ the bottle erupts making the mentos and the coke spray out of the bottle. Another reason why the eruption happens is because the nucleation site

When you mix vinegar and baking soda you get a chemical change. The chemical property that causes this is called reactivity. Baking soda’s chemical formula is NaHCO3 and it’s a compound. Vinegar’s chemical formula is CH3COOH and it’s a compound. The problem of this is how much baking soda‚ added to 10mL of vinegar‚ will cause a film canister rocket to shoot the furthest. I think 5mL will shoot the farthest because there will be more for the baking soda build up in the canister. The independent variable

Although it may be easier to just throw a bottle or soda can into a trash‚ as many lazy Americans do‚ recycling those items can be very beneficial. What everyone knows but refuses to address is that recycling is a healthy habit‚ not just for us but for the world. One reason that many people don’t recycle
