Summary:      For this project what we had to do with a group was think of a substance that could possibly spill and contaminate the ground and make a story about how that spill occurred. You then had to present that story in a news article and create an infographic based on a harmful chemical within the substance chosen. You lastly had to create a lab report based on an experiment you did to try and neutralize the substance chosen, you then had to create a newscast based on everything just said before this. The product I chose was Coke, and the harmful ingredient within coke is phosphoric acid. What I now know because of what I learned throughout this project are info on Coke & phosphoric acid, how to create a lab report, what can happen in a neutralizing experiment, and much more. What I know about Coke is that in a glass (250 ml) of Coke their is about 43 mg of phosphoric acid and in a can of Coke (12 oz) their is about 39 grams of sugar. What I know about phosp...

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

Link To Image Website Summary:      This week in science we learned about Dmitri Mendeleev (the creator of the periodic table) and the periodic table. We learned that one of the biggest reasons Dmitri Mendeleev made the periodic table was because he wanted to put it into a science textbook and by making it into a table it would fit into the textbook. We learned that for periodic table instead of saying row and column we say period(for row) and family (for column). We also learned that about a pattern that the periodic table has which is that with each period there is one more energy level for electrons. Also that elements in the same family have similar chemical reactions. We also learned about what the periodic table consists of and the families within it. The periodic table consists of metalloids, metals, and nonmetals. The families are the Alkali Metals (Family 1), Alkaline Earth Metals (Family 2) Transition Metals (families in the middle), Boron Fa...

Summary: Link      This week in science I learned more about chemistry, coke, and mainly about the very dangerous chemical within coke known as phosphoric acid. What I now know about chemistry is that the reactants in a chemical reaction have different chemical properties than the products. I also now know that. I also learned that the best  way for you to know if a chemical reaction occurs is when their is a formation of a new substance. What I know about coke is that coke itself may not be super dangerous, but their is chemicals inside of it that are dangerous (phosphoric acid). What I now know about phosphoric acid is that phosphoric acid has a chemical formula of H 3 PO 4.  Also that Phosphoric acid’s flammability is 0 and that it can be used for many things such as cleaning products, dairy products, and fertilizers. I also know the dangers of phosphoric acid contact, such as inhalation, skin and eye contact, ingestion, and other possible health effe...

     The First Question I Got Wrong Was: Copper (Cu) reacts with oxygen (O) to form copper oxide (CuO). The properties of CuO are  most likely I originally answered  similar to both copper and oxygen. The correct answer was actually  different from copper or oxygen. This is a better answer because of the fact that copper oxide is a totally different type of substance from copper and oxygen. So it makes sense how it wouldn't have similar properties to both copper and oxygen. This is why the correct answer is the better answer.       The Second Question I Got Wrong Was: Which of the following is the best evidence for a chemical reaction? I originally answered  gas bubbles. The correct answer was actually  formation of a new substance. This is a better answer because of the fact that the question asked which was the best. Technically all can signify a chemical reaction, but formation of a new substance truly shows and i...

Summary:      This week in science we learned about acids, bases, and neutrals. What I now know about acids are that they are sour, are corrosive metals, and they turn litmus paper red. I know if a substance is an acid if it is rated on the pH scale from 0-6. I also now know that in order to know what type of the three a substance is you should use the pH scale. The pH scale measures how basic or acidic a substance is. Examples of acids are orange juice, lemon juice. a carbonated drink, and vinegar. As you can see from the examples I gave that acids are sour. What I now know about neutrals are how you know if a substance is a neutral, and how you know is if the substance is rated 7 on the pH scale. Examples of neutrals are all types of salt and water. What I now know about bases are that they feel slippery, and they turn litmus paper blue. I know if a substance is a base if the substance is rated from 8-14 on the pH scale. Examples of bases are windex, deter...
