Ionic bonds; they make ionic bonds.
That would result in an exothermic reaction.
Hope this helps :)
Answer:p-hydroxybenzaldehyde is stronger acid to phenol
para-cyanophenol is stronger acid to meta-cyanophenol
o-fluorophenol is stronger acid to p-fluorophenol.
Explanation:
The PKa tool relative to Ph are used to contrast the pairs.
The pKa of phenol is 10. The pKa of p-hydroxybenzaldehyde is 9.24
The pKa for meta-cyanophenol is 8.61 and the pKa for para-cyanophenol is 7.95.
The pKa value of o-fluorophenol is 8.7, while that of the p-fluorophenol is 9.9. It's obvious that the inductive effect is more dominant at ortho-position, which results in a more acidic nature
The pKa is the pH value at which a chemical species will accept or donate a proton. The lower the pKa, the stronger the acid and the greater the ability to donate a proton in aqueous solution.
Answer:
c . a proton
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams
One could argue that photosynthesis is the most important chemical reaction of all, since it makes energy from solar energy. Plants are are at the bottom of most food chains, and you get O2 as a side product, which a lot of organisms rely on for respiration and for other chemical reactions.
I hope this helps. I'm not sure if the "passage" has any additional information since you didn't attach it.
