Hello all This is the description of the case study :
A Dip in the Dribble•
This case study is set within the context of an investigation of the environmental impact of river pollution. A fire in a warehouse has resulted in diquat dibromide and p-octylphenol entering the River Dribble. Students determine the cause of the incident and review the probable environmental impact of the chemicals released. Then they consider possible methods of analysis and, finally, commission a monitoring programme for diquat dibromide and p-octylphenol in the river by selecting a contract analysis company from the information supplied.

Title: Research Assignment: Determining the Percentage of Calcium Carbonate (CaCO3)in Eggshells 
Objective: 
The objective of this research assignment is to investigate and determine the percentage of calcium carbonate ((CaCO3) in eggshells  by titration method. (use scientific literature, online resources, and experimental data.)
Provide a list of all references cited in the assignment, including scientific articles, books, websites, and other sources used for research
Follow the instructions from the attached document:

Q. Using lead exposure paint, prepare a presentation with a 5 minute voice over it – to give your fellow students exploring the possible impacts of climate change on your toxin. For example, climate change plus lead = more dry weather, more dust, more lead in dusty places inhaled. Another example: increased risk of PAH exposure as CC increases the risk of bushfires. Your presentation needs to be referenced. Please make Powerpoint include Powerpoint generic note each page. Do not include title page.
Please use Blank Presentation (no design)
References: APA7 (last page)

Need someone to complete my aleks. Basic chem qs of school level Need to do A3, A4, A5, A6, A7, A8, A9, A10 I have completed half of them.

Make a diluted solution of an antacid, measure its pH, add indicator.
For the sample, add a measured amount of HCl , 0.1 M, count number of drops
Observe the color change, measure the final pH
Describe the reaction, why there is a color change, what was the name of indictor.
Calculate concentration of the initial solution. Include a brief report of your titration experiment using the lab manual worksheet.

This assignments is one but 8 question included. Please do it correctly because these are the exam questions.
All you need to do is read the questions and answer them correctly. 

I want to get a help with project introducing for this thesis chapter. I have attached the published paper for the work. Simply i want a little background introduction and to explain the whole paper i have attached with the literature work under the introduction. chemical structures and figures are not needed. If you want to explain with structures, please use the same numbers that are given to the structures in the paper. Feel free to add anything you think is important.

solution ; solution are homogeneous mixture of two or more non reaction component is called solution three type of solution binary , tertiary and quartanary
