Your paper should be 1-2 pages in length and conform to APA guidelines. Items that should be included, at a minimum, are a title page, an introduction, a body that answers the questions posed in the problem, and a conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. As with all written assignments, you should have in-text citations and a reference page too. Please include any tables of calculations, calculated values, and graphs associated with this problem in the body of your assignment response. Your reference section should include at least one peer-reviewed, scholarly reference.

Hydrogen and oxygen combined in ratio of 1:8 by mass to form water. What mass of o2 gas would be required to react completely with 3 g of hydrogen gas?

Objects don’t fuse to your finger when you touch them primarily because of the molecular forces involved and the structure of the materials involved.
Surface Properties: Most objects have surface properties that prevent them from adhering strongly to other surfaces. These surface properties are due to factors like roughness, chemical composition, and surface energy. These factors determine how strongly two surfaces will stick together when they come into contact.
Intermolecular Forces: Intermolecular forces are the attractive forces between molecules. When you touch an object with your finger, the molecules on the surface of your finger and the molecules on the surface of the object interact through these intermolecular forces. However, these forces are generally not strong enough to cause the two objects to fuse together permanently.
Friction: Friction between the surfaces of your finger and the object also plays a role. Friction opposes the relative motion of the surfaces in contact. While friction can create a temporary bond between surfaces, it is typically not strong enough to cause fusion.
Mechanical Properties: The mechanical properties of the materials also play a significant role. Even if two surfaces were to adhere strongly due to some combination of surface properties and intermolecular forces, the mechanical properties of the materials would likely prevent them from fusing permanently. For example, one of the materials may deform or break before fusion occurs.
Overall, the lack of fusion between objects and your finger when you touch them is a result of a combination of surface properties, intermolecular forces, friction, and mechanical properties of the materials involved. These factors prevent objects from sticking or fusing to your finger in most cases.

Assignment 1: The Annotated Bibliography
Objective: Assess sources for your research for your final presentation (for credibility, reliability, and relevance) and list references in proper APA format
Assignment Instructions: The Research Project/Presentation for this class is divided into three major Assignments, 1) annotated bibliography, 2) outline and 3) final presentation. The first part is the annotated bibliography. An annotation is a summary and evaluation, and your annotated bibliography will include a summary and evaluation of some of the sources (or references) you will use for your presentation.
To prepare for this assignment, I recommend that you do the following:
Read these directions carefully.
Review the sample annotated bibliography provided to you below.
Message me using Classroom Support with any questions!
The reason the annotated bibliography is included as part of the research project is that writing an annotated bibliography is important in that it provides excellent preparation for the final presentation. One of the issues regarding any type of research, especially in chemistry, is the credibility of the sources used, particularly those obtained from various websites. By forcing you to evaluate each of your potential sources carefully, the annotated bibliography helps you determine if in fact the source you chose is credible and helps you determine how relevant it is to your topic and understand the topic better which will help you develop your presentation.
For this project, you will assess three sources to include:
1) a complete citation for each source,
2) a summary of each source, and
3) an evaluation of each source.
Three sources are required for this assignment (i.e., you are to write an annotation for each source). However, you must use five or more sources in your final presentation.
Use this TEMPLATE to summarize and evaluate each of your three sources.
Citation:
Written in APA reference list format. For more help with formatting, see APA handout.
Summary:
What is the purpose of the source, review article, original research? What topics are covered? This section is generally 4-6 sentences that summarize the author’s main point. For more help, see this link on paraphrasing sources.
Evaluation:
After summarizing the article (or research paper or book), it is necessary to evaluate it and state where you found it – its source (e.g., journal, website, etc.). Briefly answer the following questions in 4-6 sentences:
What is the format or type of source (e.g., peer-reviewed journal paper, website, book)? How reliable is the information in the article, and how credible is the source (e.g., website’s sponsoring organization, journal or book publisher) and the author(s)?
For more help, see this handout on evaluating resources.

Evaluation: Please review the Annotated Bibliography Grading Criteria that describes how your annotated bibliography will be graded.

All grades are to a large extent (50% for Pre-Labs) based upon your work being thorough, complete and of good quality; you need to be showing me all of the relevant work in getting to the questions answers. Good work includes showing all of the units throughout every calculation. Being too brief is the equivalent of being incomplete. 2) Laboratory Experiment 8 If you have not already done so then study the Laboratory Experiment 8 Write-UpDownload Laboratory Experiment 8 Write-Up and then do the Laboratory Experiment 8 Pre-LabDownload Laboratory Experiment 8 Pre-Lab for this experiment.
