Answer:
9
Explanation:
The structure of fluorophore used in the experiments has been drawn in the attachment. And from the drawing counting we can say that there are 9 sp2-hybridized carbon atoms present. Fiuorophores are a fluorescent chemical compound that can re-emit light upon light excitation. Normally used to produce absorbance and emission spectra.
Answer:
this is an example of a Simple sentence
Answer:
![[OH^-]=1.7x10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.7x10%5E%7B-6%7DM)
Explanation:
Hello!
In this case, since the pOH of a solution can be computed when knowing the pH as shown below:
And therefore, the concentration of hydroxide ions based on the definition of pH:
![[OH^-]=10^{-pOH}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-pOH%7D)
In such a way, we obtain:
![[OH^-]=10^{-5.78}=1.7x10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-5.78%7D%3D1.7x10%5E%7B-6%7DM)

The metals become less reactive.
"Like dissolves like" is an expression used by chemists to remember how some solvents work. It refers to "polar" and "non-polar" solvents and solutes. Basic example: Water is polar. Oil is non polar. Like dissolves like, that means polar dissolves polar, so water dissolves salt.
