Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed. Some of the factors that can affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min

When different people come in contact with other people their reactions are almost never the same from person to person. This reaction that humans have with different variables in society is what I would like to identify as my social behavior among human groups. This reaction behavior is very interesting to me because I would like to know how come humans get different reactions or feelings in certain situations. This topic leaves me with a few questions that I would like to figure out through research

The Gilded Age took place in America between the 1870s and 1890s. America was in an era of greed and political corruption.

The early 20th century was a time of dramatic technological and social change. America was protected by the Atlantic Ocean and American interests became more affiliated with the global economy. In the 1900s automobiles were seen as a luxury item that only the rich could afford‚ but with Henry Ford’s assembly line the price of cars became much cheaper. Changes in communication were also taking off. Alexander Graham Bell’s invention of the telephone became more widespread and the invention of radio

Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. Enzymes are catalyst for biochemical reactions; Enzymes lower the activation ATP so a reaction can begin over the energy barriers. In this lab‚ a discussion of the enzymes reaction to heat will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches too

The Change Over Time of time between the Middle Ages and Reformation was impacted enormously by multiple factors. The Middle ages was the period of time between the fall of the Roman Empire‚ and the uprising of the renaissance in about 1330s to roughly 1700s.
