Hey DrBob, I posted an answer to you question on my lab report just to let you know what the y= and r^2 is

thanks. I'll take a look.

Let me know if that is all you need. If you need something additional, please itemize what you need done. Also, I will need to know if you digested the sample or if the samples were placed in solution for you and you were given the prepared sample to which you added the 1-10 phenanthroline.

I had to take cereal crush it up and place it in a crucible and cook it tell it was black ash. Then I took that burnt ceral and placed it into a beaker with HCL and water and boiled it tell the cereal was like a liquid cause coming out of the crucible it was in a circle compound shape so we had to break it up and then put it through a filter so then when we were done the flask just had the HCL and the liquid from the cooked cereal

Thanks.

Hello! I'm not DrBob, but I'd be happy to help you out. If you want to know what the "y=" and "r^2" values mean in the context of your lab report, here's a quick explanation:

1. "y=": In scientific experiments, researchers often use mathematical models to represent the relationship between variables. The "y=" in your lab report signifies the equation of the model that best fits your data. It shows how the dependent variable (usually represented as 'y') changes with changes in the independent variable(s). The specific equation will depend on the type of analysis or statistical method you used to analyze your data.

2. "r^2" (R-squared): R-squared is a statistical measure that represents the proportion of the variation in the dependent variable that is accounted for by the independent variable(s) in your model. It ranges from 0 to 1 and is often expressed as a percentage. A larger R-squared value indicates a stronger relationship between the variables.

To get these values for your lab report, you likely had to perform a regression analysis or use statistical software. The specific method and software used may vary depending on the nature of your experiment. If you're unsure of how you obtained these values, it'd be best to reach out to your instructor or lab partner for further clarification.

Hope this helps! If you have any more questions, feel free to ask.
