C.Lightweight and durable.
Explanation:
The given reaction equation is as follows.
So, rate constants for different reactants and products written as follows.
As per the reaction equation, the stoichiometric coefficients of reactants and products are as follows.
A = -2
B = -1
C = 1
Therefore,
Hence, 
= 
= 12.5 
Thus, we can conclude that 
and 
are 12.5 .
Answer:
Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. The membrane also maintains the cell potential.
Explanation:
(see above)
Answer:
a. There are only 5 electrons in 2p. 2p should be filled with 6 electrons prior to 3s and 3p
b. There are 8 electrons in 2p. 2p should be filled only with 6 electrons (not 8)
Explanation:
The typical electron configuration: 1s2 2s2 2p6 3s2 3p6
a. There are only 5 electrons in 2p
=> should be 1s2 2s2 2p6 3s2 3p2
b. There are 8 electrons in 2p
=> should be 1s2 2s2 2p6 3s2 3p1
