<u>Answer:</u> The number of electrons for n = 0, 1 and 2 are 2, 6 and 10 respectively.
<u>Explanation:</u>
Huckel's rule is used to determine the aromaticity in a compound. The number of delocalized 
electrons are calculated by using the equation:
where,
n = 0 or any whole number
- Calculating the value of electrons for n = 0
Putting values in above equation, we get:
- Calculating the value of electrons for n = 1
Putting values in above equation, we get:
- Calculating the value of electrons for n = 2
Putting values in above equation, we get:
Hence, the number of electrons for n = 0, 1 and 2 are 2, 6 and 10 respectively.
a. Hydrogen
Hydrogen has a line at 410 nm.
Mercury has a line at 405 nm.
Sodium and neon have no lines near 412 nm.
Answer:
A solution is a homogeneous mixture of two or more substances. The particles of solute in a solution cannot be seen by the naked eye. A solution does not allow beams of light to scatter.
Explanation:
Depending in the category of the Hurricane, you make experience different levels of wind power and destruction. Hurricanes only have 5 categories ranking from Category 1 to Category 5. The smallest category is category 1 making category 5 the largest. The bigger the category, the more wind or destruction you'll experience.
The answer is C, because if the copper has a +2 charge, the fluoride must have a -2 charge in order to cancel out.
