Answer:
B carbon
Explanation
Lewis structure or dot structure is an easy way to get the bonding details of atoms in a molecule. If we talk about methane molecule carbon is central atom with four electrons that are bonded to four hydrogen atoms and each bond is single covalent bond.
Please see attached figure,
Hope it helps!
Answer:
a. -58 millivolts
Explanation:
The given Nernst equation is:
The equilibrium potential given by the Nernst equation can be determined by using the formula:
where:
gas constant(R) = 8.314 J/K/mol
Temperature (T) = (20+273)K
= 298K
Faraday constant F = 96485 C/mol
Number of electron on Cl = -1
Answer:
238 amu
Explanation:
(234 * 0.0001) + (235 * 0.0071) + (238 * 0.9928) = 238
