How could the student whose report you received have improved his or her lab report?
Report 3 could have been improved by talking about what sodium carbonate and sodium bicarbonate is in the introduction as well as removing the lists under Materials and Methods. The Materials and Methods should always be in sentence form in the past tense. Also more than two trials should have been done because replication is very important to scientific experiments. This ensures that there are no outliers in the results. Also, the author should have avoided personal pronouns like “I” in the conclusion. A sentence that could replace the last would be something like “Because the actual percent composition of the mixture is unknown, the accuracy of the current

First, there are journals where scientists are welcome to publish their findings. This is an easy way for scientists to have easy access to work done by other professionals in their field. However, this is not the only method of communication. They can also give presentations at things such as TED talk that allows them to display their results to an interested audience. In a like manner, the media often finds research done by scientists and publishes it. This is not as common though because the media is more interested in stories that will get them more attention from the public. Due to this, they often only publish findings that tend to be simple and relevant to most people since scientists are often only a minority in the public.
What makes a good lab report? A good lab report is clear and concise. It includes a number of things but the foundation is giving the lab report good background information, having clear information, and clear data. A lab report must have a good abstract, discussion, procedure, observation, calculations, and conclusion. Also, it must have labeled graphs and tables if applicable.

In this case, the grams of sodium carbonate (Na₂CO₃) is what is measured after the reaction takes place. Sodium carbonate and sodium bicarbonate is what makes up the initial mixture. Therefore, the leftover sodium carbonate can be reused allowing this experiment to fit in the definition of green chemistry.
When comparing the results above, the outlier of the data,1.358% NaHCO3, was inconsistent with the other data. This caused the average of the data above to be significantly less than the other averages displayed. The averages being discussed represent the amount of NaHCO₃ that is present in the reactant. Groups 1 and 4 had very similar data to the data above. Two of the values that were pretty consistent seemed to be 38% and 57% NaHCO3 in mixture. This means that the two mixtures had approximately the same amount of sodium bicarbonate to begin with. However, the differences in average shows that each different mixture is composed of different amounts of sodium bicarbonate and sodium carbonate. Although they seemed to be similar mixtures, the amounts of each substance are inconsistent for
This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.
When your lab report is complete, submit this document to your instructor in your assignment box.
No credit will be given for this lab report if the Data section is not completely filled out and if the required photographs are not received. At least one photograph must show the student’s face.

This section should be concise. List each step of the procedure in either numbered format or you can use bullet points. Remember to always use PASSIVE language when writing lab reports. Never use I placed HCl into a 50mL beaker, instead say 50 mL HCl was placed in a 50 mL beaker.

Answer the lab questions for this week and summarize the lab experience using this form.
All work must be well-written and organized. If your penmanship is poor, you must type all responses. If you need to organize your thoughts, please use a separate sheet of paper. A major objective of this lab course is to develop skills in scientific communication. Just having the right “answer” is not good enough – you must communicate clearly and succinctly and use terms and concepts correctly. When typing, all sections must have a line spacing of 1.5 to give room for TA feedback (the document is set to this spacing).
Purpose: The purpose of this investigation is to learn how to write a proper lab report and how to
Use this document to report your findings from the CardioLab Exploration Experiment. The lab report consists of three sections: Data, Exploration, and Lab Summary.
A lab write up can make or break your results in the science world. Structure is very important. The article “Materials & Methods” is basically a step by step how to guide for anyone learning how to write a lab report.
Based on the mass of the products in the beaker after the decomposition reaction which was 1.98g, the correct decomposition reaction is when the sodium hydrogen carbonate decomposed into sodium carbonate, water vapor, and carbon dioxide gas. Since the water vapor and carbon dioxide would have escaped the beaker during the reaction, sodium carbonate would have been the only remaining product in the beaker. Sodium carbonate is the product remaining in the beaker because the theoretical yield of the sodium carbonate is the closest to that of the actual yield of all of the possible products produced. The sodium carbonate produced from this reaction had a mass of 1.98g, compared to the theoretical yield of 1.84g which gave this reaction a percent yield of 107.7%. Although the percent yield is higher than 100% this may have been caused by an incomplete reaction since the temperature the sodium hydrogen carbonate was to be heated to was unknown along with the time that it should be heated. The reaction where the sodium hydrogen carbonate decomposed into sodium, water vapor, carbon monoxide and oxygen gas was not a likely reaction to occur in this experiment. This is because sodium hydrogen carbonate is used for baking purposes which it would not be used for if the decomposition of the compound resulted in the creation of carbon monoxide a poisonous gas. If cobalt chlorine was used to test if water vapor was given off in an experiment and it changed in colour it would suggest
