Step-by-step explanation:
because in the periodic table nitrogen is 7, and oxygen is 16
On 15 angle 1 and 2 would be 150 degrees i think, i could be wrong.
On 16 angle 1 would be 140 degrees and angle 2 would be 40 degrees. hope this helps
It's C or A if it's C that's right if it's A I'm wrong be pretty sure it is C
-2/3 <em>b</em> + 4 = 0
Add -4 to both sides to eliminate the 4 on the left:
-2/3 <em>b</em> + 4 - 4 = - 4
-2/3 <em>b</em> = -4
Multiply both sides by -3/2 to eliminate the -2/3 on the left:
-3/2 • (-2/3 <em>b</em>) = -3/2 • 4
<em>b</em> = -12/2
Simplify the solution:
<em>b</em> = -6
