P. 15 Q’s P. 19 Q

P. 15

The difference between a compound and an element: an element is any material that cannot be broken down into something simpler, and a compound is what is made when multiple elements combine.

The information a chemical formula of a compound provides is what elements make up the compound, and how many atoms are in each element. 

P. 19

Natural Gas: CH4

A carbon atom and 4 hydrogen atoms.

The property of the compound is different from the property of each element since in order to be a compound, you need two different elements. One separate carbon atom and another separate hydrogen atoms are completely different from CH4, unless combined together. 


Chem Talk

After reading Chem Talk last night, my curiosity towards chemistry has risen very much so. Every single thing in the world is made up of these elements, so why not spend time to learn and understand them? After a first glance of a chemistry book, all of it would seem very hard to do. But now after understanding the basics of the basics, I feel as if learning chemistry will still be a challenge, but an interesting one. I hope that as the year continues, the class can start to understand the elements and chemical formulas, because every deserves the chance to know about chemistry. Some might debate no, but people should know what the universe is made up of and how these particles of matter interact. A little confusion came up near the end of the reading, but it seemed more than possible to understand with some studying and class talks.

Blog #2 – Units

What is a unit?

I believe that a unit is something that helps someone understand how many of something they have. For example, someone could have 1 gram of sugar vs. having 1 pound of salt. Obviously, I can tell that there is more salt because of the units of measurement used.

For my unit, I will choose the United States customary units. This is the unit system that consists of the American way of measuring things. For example inches, feet, yards, etc. These units are only used in the US, while most of the world uses the metric system.

In relation with each other, these units will add up. The most basic of the length measurement is an inch. Twelve of these makes up a foot, and then three of those make a up a yard, and then onto miles. A yard can often be compared to a meter, and the same for inch to centimeter.

This unit system was based off of the the english or imperial that was used in Great Britain. At first during the 19th century in America, it was decided that the metric system would be the designated system for measuring things in business. As time went on, people just thought it was easier to use inches rather than centimeters when distances had to be cut in halves, thirds, and quarters. I personally would choose this system over the metric.

I thought that our recent discussion about having an open and growing type of mindset was very interesting. I myself believe that a growth mindset is the better than having a fixed one, but both sides have their ups and downs.

Being able to not fear failure is something that some people have a hard time adjusting to. Some might get nervous about how they are looked at, whether smart or stupid. But in order to acquire a growth based mindset, it is a necessity for you to not be afraid to look “stupid”. I think that it is stupid when someone will not try to answer a question, just because it will make them look dumb. That person would probably look worse if they didn’t try the problem, and not benefit from the situation at all. People who want to learn stuff will by definition end up knowing more stuff than the people who did not want to learn. Most people want to grow and learn, but the ones who are afraid of being wrong need to change their minds.

In my observations, I think that it is best for one to choose a growing mindset. It just does not make sense for someone who wants to look smart not to learn anything in the first place. There you have it.
