Answer:
It has 3 sigma bonds
Explanation:
A sigma bond is a covalent interaction between two atoms, these bonds are the strongest type of covalent bonds and they are formed by the overlap of atomic orbitals.
The nitrogen is bond to the bromine atoms through sigma bonds, which means that exist 3 sigma bonds in the molecule.
this molecule has a trigonal pyramid geometry due to the free pair of nitrogen electrons.
Answer: B. 0.015 mole/L
Explanation:
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of solution = 0.010 M
Volume of solution = 10 mL
Putting values in equation 1, we get:
a)
1 mole of contains = 1 mol of
Thus of contain= mol of
b)
1 mole of contains = 2 mol of
Thus of contain= mol of
Total
The molar concentration of in a solution is 0.015 M
2 to 4. Im pretty sure you might have to check me on it but as far as i know 2 to 4 years.

A tall, horizontally subdivided or packed container for fractional distillation in which vapor passes upward and condensing liquid flows downward. The vapor becomes progressively enriched in more volatile components as it ascends, and the less volatile components become concentrated in the descending liquid, which can be drawn off.
Answer:
Moles = Mass / Mr
Moles = Concentration x Volume
Explanation:
Moles can be worked out in several ways depending on the information you are given. Some of the equations containing moles are:
Moles = Mass / Mr
Moles = Concentration x Volume
