(2) Acids and bases are both H+ donors.
(3) Acids are H+ acceptors, and bases are H+ donors.
(4) Acids are H+ donors, and bases are H+ acceptors.
Answer: Option (4) is the correct answer.
Explanation:
According to Bronsted and Lowry, acids are the species which can donate hydrogen or ions.
Whereas bases are the species which can accept hydrogen or ions.
Thus, we can conclude that the statement acids are donors, and bases are acceptors describes an alternate theory of acids and bases.
Answer:
C. All electron carriers are mobile and hydrophobic
Explanation:
Hello,
In this case, it is widely known that the electron carriers move inside the inner mitochondrial membrane and consequently move electrons from one to another. In such a way, they are mobile, therefore they are largely hydrophobic as long as they are inside the membrane.
For instance, the cytochrome c is a water-soluble protein in a large range, therefore, the answer is: C. All electron carriers are mobile and hydrophobic.
Best regards.
Ca(OH)2
In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:
2HCl + Ca(OH)2 = CaCl2 + 2H2O
