A. Draw a graph that shows the relative concentration of BTB from the center of the drop to the edge of where the paper was wet.
See sample graph below question 3
b. In the above graph, did you have the concentration go to zero when you could no
longer see BTB? Or did you assume BTB was still there albeit at invisible levels?
c. Shade in the portions of both graphs where you were making assumptions (saying
things you have no evidence for) about the concentration of BTB.
2. From your data, could you infer that the paper towel is acidic? Explain.
3. How could you prove that your inference about the acidity of the paper is true?

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
