Answer:
12.7.
Explanation:
∵ pOH = - log[OH⁻].
[OH⁻] = 0.051 M.
∴ pOH = - log[OH⁻] = - log(0.051 M) = 1.29.
∵ pH + pOH = 14.
∴ pH = 14 - pOH = 14 - 1.292 = 12.7.
Answer:
4 electrons .
Explanation:
Carbon must gain four electrons to attain noble gas configuration. Carbon has a total of 6 electrons of which 4 are valence electrons. The four electrons are found in the outermost shell, for a stable configuration Carbon should gain four more electrons to give a 2.8 shell configuration. Most noble gases have 8 electrons in their outer shell with the exception of Helium. By gaining 4 electrons Carbon will have the same shell configuration as Neon.
