with minor modifications to take the general theory of relativity into account. My experiment is labeled The Marble Dropping experiment and has been done in many different ways using different methods and equipment. The marble I’m talking about is different to the Marble used in flooring or other things. Marble: a small ball of colored glass or similar material used as a toy. Marble is more specifically classified as a Metamorphic Rock. A Metamorphic Rock: a type of rock which has been changed

reaction is a weak nucleophile attack group. Hydrochloric acid is a weak group because it has no negative charge‚ and works well for the reaction. Reaction for formation of 2-chloro-2-methylbutane The goal of this experiment was to form 2-chloro-2-methylbutane by addition of HCl‚ causing a Sn1 reaction to occur. Chemical Reactions Safety 1.

Is there really such a thing as rain with acid in it? Yes‚ acid rain is a very real phenomenon worldwide‚ and it’s been documented since the 1800s‚ as the Industrial Revolution caused the burning of fossil fuels like coal‚ gas and oil. When these fuels or any other organic material like wood or paper are burned‚ they release compounds like sulfur dioxide (SO2) and nitrous oxides (NOx) into the air. Are SO2 and NOx the causes of acid rain? Indirectly‚ yes. When SO2 and NOx enter the atmosphere

Cause and Effect on Acid Rain Introduction Beautifully crafted statues are now worn out or severely damaged‚ aquatic wildlife population are dying off‚ forests have lost the leaves that protect their trees and produce food‚ and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acid rain. Most people don’t understand the concept or science behind acid rain. The common belief is that it’s a natural process‚ but it’s actually

If you have marble flooring and you want your marble flooring to look great‚ you need to take proper care of your flooring. A large part of taking care of marble flooring involves waxing‚ stripping and polishing your floors. Over time‚ the wax used to make your marble floors shine tends to start to build up and makes your floors look foggy instead of shiny. When this happens‚ you need to remove the wax on your marble floors through a process called stripping. Necessary Supplies You will not need

the Parthenon Marbles‚ also known as the Elgin Marbles‚ from Lord Elgin on July 11‚ 1816 through an Act of Parliament (1). The Parthenon marbles consist of 115 panels of frieze and 92 mesotopes of which the British Museum owns 56 panels of the frieze and 15 mesotopes. The museum also owns 17 pedimental figures‚ and thus houses about half of surviving sculptures of the Parthenon while the other half is in Athens (2). The legal circumstances surrounding Lord Elgin’s removal of the marbles is questionable

- 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops it so that the marble would fall through it‚ therefore recording the velocity in km/h. There was also a box at the bottom of the mechanism to catch the marble every

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules
