If The flask and its contents had a mass of 120 grams before the experiment and a mass of 120 grams after the experiment Which conclusion can best be made from these measurements?

That the Law of Conservation of Matter has been proven to be true once again.
I could also conclude that the experiment occured within a closed sytem where no gas was lost.
So many conclusions, so little time.

What is the purpose of stirring the mixture in the calorimiter after the hot sample was poured into it?
It is doubtful that the walls of the sample holder in the calorimeter start at the same temperature as the sample. By stirring it, you can help equalize the temperature throughout the sample and bring the sample and the sample holder into thermal equilibrium before you start the measurements.
Why must hypothesis before you do experiment?
because hypothesis is a trial idea
What does color mean in chemistry?
it means what color it turns after or before the experiment
What is conclusion of volcano?
Conclusion The end of the experiment 1. The volcano erupted like a volcano really would. 2. We mixed the ingredients around and it erupted longer. 3. We added more soap and it foamed more.
What will be your dependent variable in this experiment My experiment is does chilling an onion before cutting prevent you from crying I put three onions in the freezer refrigerator and kitchen?
The dependant variable in this experiment would be the amount of 'crying' resulting from the cutting of each onion.
What is the difference between a prediction and a conclusion?
A prediction is what you think will happen BEFORE the experiment is followed through with, a conclusion is what you observe and conclude after the experiment has been completed.
What is the difference between a hypothesis and a conclusion?
The hypothesis is the guess you make before the experiment. The conclusion the summaryof you results, and you can discuss whether your hypothesis was correct or not.
How many times should a experiment be repeated before reaching a conclusion?
as much data as possible can be colleced in the time availble
How do scientists make theories?
Fist the scientist figures out the aim of their experiment. Then they make a prediction. And then they make a theory before actually doing their experiment. After the experiment they make a conclusion and then evaluate their experiment (what went wrong, how things could be better...). Hope this helped! :)
What are the five parts of a well designed experiment?
Five parts of a well designed experiment includes a question that you want to solve, a hypothesis which you are going to test, the data, and conclusion. And of course the actual experiment. And before all this you must observe. 1-Observation 2-Question 3-Making a hypothesis 4-Experiment 5-Collect Data 6-Make a Conclusion

Conclusion in science projects?
The conclusion in your scientific reports should include: * what were the assumptions and what results were you expecting before doing the experiment * what method(s) or approach(es) did you use in the experiment * what are the results? * do your results agree or support with your assumptions? If yes, why? If no, what do you suggest to do for the next experiment. Preferably, the conclusion is much shorter than the body of your report. One paragraph can suffice, but try to keep it less than 2 typewritten pages. Be concise. Keep your sentences short. This section may be the only one that your peers or superiors will read. ==================
Does a theory go in or before the conclusion?

The hypothesis comes before the conclusion. The conclusion is the very last step!
What goes first introduction or table of contents?
Table of contents and then intro. Before the table of contents goes the title page, copyright, and dedication.
In a report what comes first - conclusion or recommendation?
The conclusion comes before the recommendation.
What ratios that measurements must be changed to the same units before simplifying?
All ratio measurements must be in the same units before simplifying
