Parents always make decisions for their children even if they don’t exactly know what their child really wants. Everyone would agree that parents want only the best for their children‚ but is their decision always the best for their kids? In “Stuck in Neutral” by Terry Trueman Shawn’s father expresses thousands of emotions‚ such as sadness‚ anger‚ love. His emotions are justifiable but not all of his actions are. From the perspective

reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C

In the book Stuck In Neutral‚ considered to be an young adult novel‚ the author Terry Trueman writes a story about a 14 years old boy that suffers from cerebral palsy. Terry’s own son suffers from this conditions. His son was the inspiration to writing this book because he wanted to educate others what cerebral palsy was and how to treat those who suffer from this. The young boy in the book that suffers from cerebral palsy is named Shawn. The whole book is written in the first person’s point of

Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to

Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.
