Explanation:
It is known that the oxidation of to is catalyzed by
. In this process, two steps are involved as follows.
(a)
whereas, the second step is
(b)
Balancing the above reaction by multiplying equation (a) by 2 as follows.
(c)
Now, on adding both reaction equations (b) and (c) the net reaction equation will be as follows.
Thus, we can conclude that the equation for the final overall oxidation of by to give is as follows.
The answer is C. A, B, and C would depend on what type of electron it is.
tree rings
Explanation:
A dendrochronologist interprets tree rings to ascertain the age of a particular tree.
Dendrochronology is a a scientific process that involves the dating of tree rings to determine the age of a particular tree.
- It is sometimes called tree-ring dating.
- This method of dating is mostly applicable to woody trees that have large years of growth.
- New rings develops in order to accommodate new structural materials like the secondary xylem and phloem in them.
- The nature of this secondary growth pattern can be used to systematically determine how old a particular tree is.

Answer:
Formula mass = 58.09 g
Explanation:
Formula mass of a given molecule is defined as the sum of atomic masses of elements forming the empirical formula of that molecule.
In order to calculate the formula mass of propanol, following data is required;
Empirical Formula of Propanol:
The empirical formula of Propanol is C₃H₆O (also the molecular formula) as it is the lowest possible atomic ratio of the given elements.
Atomic Masses of Elements:
Carbon = 12.01 g/mol
Hydrogen = 1.01 g/mol
Oxygen = 16.00 g/mol
Hence,
Formula mass = (At. mass of C)₃ + (At. mass of H)₆ + (At. mass of O)
Formula mass = (12.01)₃ + (1.01)₆ + (16.00)
Formula mass = 36.03 + 6.06 + 16.00
Formula mass = 58.09 g
