September 13, 2023CHM1100C Week 1 Description
General Chemistry is a one-semester, general chemistry course for the life science (biology, biochemistry, and pre-medicine), physical sciences (physics and astronomy) and social sciences (psychology, sociology, and anthropology) majors. The course covers topics such as periodic trends, atomic structure, molecular structure, chemical bonding and molecules. The purpose of the course is to provide students with an overview of the basic principles of chemistry that will serve them well in future classes in their chosen fields.
Chemistry is a combination of various subjects like physics, mathematics, environmental science etc. Although it is an elective subject for most of the colleges but it plays very important role in our day to day life. For example: You can’t really study without knowing how electricity flows through wires or can’t learn about the properties of matter without studying chemistry. If you want to be a chemist than you should definitely take CHM1100C- General Chemistry Course at UOP.
The main aim of this subject is to develop good understanding about some central topics in chemistry including atomic structure; periodic trends; chemical bonding; solutions and stoichiometry; thermochemistry; kinetics; acid-base equilibria; organic chemistry including biological molecules; analytical chemistry including physical methods and instrumentation techniques.

CHM1100C Week 1 MCQ’s (20 Multiple Choice Questions)
Course.
For questions 1–5, choose the most appropriate word from the options given. Each question in this section is based on a short reading passage.
Questions 1–5
In order to protect themselves and their environment, it is important for people to know how they can prevent pollution of water. There are three different ways that water can be polluted:
1) A person may do something that causes pollution by accident. For example, if a person dumps an empty glass bottle down the sink, there is a chance that it will be emptied into the sewer system and end up in the ocean where it will not belong because its original owner has not yet replaced it with a new one.
2) A person may dump something like gasoline or oil down the drain when cleaning their car. The gasoline may damage the pipes and cause them to break down which will lead to leaks in other parts of the house.
3) A person may let chemicals leak into their yard. If they let chemicals such as pesticides enter their yard, they could end up harming themselves and anyone who might come into contact with them (such as pets). Pesticides can also cause harm to other animals and plants nearby if they are released too close to these things. It would be best for everyone involved if these problems were avoided.
Read the passage carefully and answer questions 1–5.
The word “pollution” means _________
A) anything that creates or adds onto something else
B) something very bad that happens in a place where people live
C) something that happens when something goes wrong with something else
D) something very clean that happens somewhere else
E) a chemical substance released into the air when things are burned
Question 6 (a): Which sentence is closest in meaning to “Water usually contains _________”.
Question 7 (a): Which sentence is closest in meaning to “There are many ways for water to get polluted”?
Question 8 (b): Which sentence is closest in meaning to “Polluted water affects people”.
Question 9 (c): Choose among the following statements, which one best describes how we know we need rainwater storage systems?
(a) We cannot find out what is causing droughts.
(b) We have problems with our current water supply system as well as our population grows rapidly every year.
(c) We have used up most of our rainwater, so we should find ways of storing more of it for future use.
(d) We must stop using our current rainwater storage systems before we pollute our fresh drinking water sources.
(e) Our country does not have enough rainwater storage systems yet. Therefore, we should build more rainwater storage systems.
Question 10 (d): Choose among the following statements which one best describes why we need rainwater storage systems:
(a) To store fresh drinking water sources for later use.
