Hypothesis refers to the discovery and raising of problems in observation, after experiment and fact verification, the various correct and reasonable explanations of the problem can rise to theory and become a successful hypothesis.
Answer:
The correct answer is A all chemical bonds are hard to break
Explanation:
The minimum amount of energy that is required to break a chemical bond is known as bond energy.
Different amount of energy is required to break different bonds. For example High amount of energy is required to break covalent bond whereas a low amount of energy is required to break non covalent bonds such as hydrogen bond, hydrophobic interaction,van der waal interaction etc.
PH + PoH is equal to 14.
You’re given the concentration of OH. Taking the logarithm of that (log [OH]) gives you PoH. Subtract 14 from answer to get PH. Hope that helps :-)
