ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

Should Toys Be More Gender-Neutral? This topic is one that does hit me close to home because I have a ten year old sister and a few other cousins younger than her. Though I did not really think about this topic much until now. It is the twenty-first century after all‚ shouldn’t gender-neutral toys be a thing? With this I researched this topic more with this help of my sister to learn more about. Though sadly I do believe that toys should be more gender-neutral even though they currently aren’t.

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance

to a garden (let alone the beach) their streets are full of cars; school playgrounds are usually flat‚ sterile areas of concrete which offer no interest or little opportunity for interaction.” The consequences of this according to his theory of Compound Flexibility is that children who have little control over the world inevitably have fewer positive experiences‚ which in turn slows the development of their self confidence. Loose-parts theory has also been referred to by Bob Hughes in his elucidation

1999 Adipic Acid (98/99-3) Currently operating commercial production processes for adipic acid depend on the production or purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric acid oxidation. KA

There are different types of Compound Interest. Interest is the amount of money earned in a saving account. * Simple Interest: Interest calculated once on the principal. * Compound Interest: Interest calculated for a given segment of time of the investment. For example‚ compounded monthly‚ means the interest is calculated each month and combined with the principal. So‚ for the next month‚ interest is earned on the interest.
