Answer:
+2
Explanation:
Since O &F Are more electronegative than N,
F=-1
2F=-2
O=-2
also the compound is neutral,
then 2N+2F+O=0
2N-2-2=0
2N=+4
N=+2
Given the reaction in the photo you posted, the particle that is represented by the X will be {30 / 15 P }. The correct answer will be choice number 4 which is located on the graph.
17°C
Explanation:
this is way I got for you
gdm^-3/gmol^-1
g/g=1 dm^-3/1=dm^3 1/mol^-1=mol^1 1 x dm^-3 x mol^1 mol/dm^3
To convert from g/dm^3 to mol/dm^3 you have to divide g/dm^3 by g/mol or the molecular mass.
