Please do all that by typing not hand written
chemistry about (gases, liquids,solids )
Students are required to find a news article and write a short paper (400-600 words) explaining the article subject using chemistry terms/concepts discussed and learned in this course. This assignment is NOT to simply write a summary of an article. Be EXTREMELY CAREFUL to NOT plagiarize the article. The complete article, or web address of the article, must be included within the submitted paper Word document file. Only Word formats (.doc or .docx) are acceptable. Late submissions will NOT be accepted and will result in zero points for this assignment.
CHEM110 – M01 Experiment: Measurement and Significant Figures (HOL)
Chemistry Assignment Help Submission RequirementsYou will create a formal lab report using a digital word processing program (Microsoft Word, Google Docs, etc.) and submit it as a PDF within this assignment page.
All lab reports will be organized into three sections:
Design
Title and Purpose
Methodology: Explain the procedure in your own words. What are you doing to achieve the experiment’s purpose?
Pre-Lab Questions: These are asked in the “Lab Workbook”. Answer in complete sentences.
Results
Observations: Take 2-3 photos of your at-home experiment at crucial points in the procedure and embed them into the digital report. Provide a description of any observations.
Data Tables and Graphs (if applicable): Create digitally, within a word processing or spreadsheet application.
Calculations: Complete all calculations by hand, take photos, and embed them into the digital report. If calculations are involved in the experiment, then they must be provided in this section.
Discussion
Analysis: Explain the point of the lab in your own words. Address the lab’s “Purpose” thoroughly, citing and connecting two main sources: your experimental results and your course content.
Post-Lab Questions: These are asked in the “Lab Workbook”. Answer in complete sentences

ANSWER FOLLOWING QUESTIONS MULTIPLE CHOICE
1) Which of the following is not a true statement regarding metabolic pathways?
a) Metabolic pathways can be regulated genetically by altering expression levels of enzymes in the pathway.
b) Metabolic pathways can be regulated allosterically by small molecule products of the pathway.
c)Metabolic pathways can be regulated covalently by transient modification or complete proteolysis of enzymes in the pathway.
d)Biosynthetic pathways are identical to breakdown pathways but run in reverse.
2)Mg2 is requirement of all protein kinase enzymes. Which statement below best describes the role played by Mg2 in a typical kinase enzyme-catalyzed reaction?
a)Mg2 is a metal ion co-factor that is required for the enzyme-catalyzed reaction to occur.
