Answer:
Net number of sigma bonds = 1
Net number of pi bonds = 2
Overall bond order = 3
Explanation:
Electronic configuration of N2 ia
1s2 2s2 2p3
There is head to head overlap in pz orbital. Thus, there is one sigma bond
Pi bond is formed whenever there is side wise overlapping. Since both px and py undergoes overlapping to form pi bond, there are two pi bonds
Bond order = 0.5 (bonding electron – antibonding electron)
= 0.5 (8-2) = 0.5*6 = 3
Answer:
B) 3.0 g/mL

Answer:
C. A ball dropped from a height of 10 m will hit the ground at a higher speed than an identical ball dropped from a height of 5 m.
Explanation:
The statement of the hypothesis is that " the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up ".
The hypothesis statement is quite explicit. We can deduce that objects at a higher height above the ground will hit the ground much more faster and harder compared to those at a shorter height.
A ball at height of 10m is expected to drop with a higher speed on the ground compared to an identical ball at a height of 5m.
If the balls are at the same height, they are expected to fall with the same speed so far they are identical. Also, a ball at a shorter height will fall at a lower speed.

Hello there!
In this case, considering the Avogadro's gas law, which treats the volume and moles in a directly proportional way via:
Which can be solved for the final volume, V2, as shown below:
Thus, by plugging in the given data, we obtain:
