n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4
3 MgCl2 + N2 = Mg3N2 + 3 Cl2
If: n2 = 19 Then: n = the square root of 19.
n2 + 9n + 18 = (n + 6)(n + 3)
I'm assuming you meant m2-n2+196 m2-n2=-196 m2=-196+n2 m=14i+n n=m-14i
n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4
3 MgCl2 + N2 = Mg3N2 + 3 Cl2
If: n2 = 19 Then: n = the square root of 19.
Conditional statement: If n2 equals 64, then n equals 8, where n2 equals 64 is the hypothesis, and n equals 8 is the conclusion. In order to obtain the converse of the conditional we reverse the 2 clauses, then the original conclusion becomes the new hypothesis and the original hypothesis becomes the new conclusion. So that, Converse: If n equals 8, then n2 equals 64.
N2
4n2-25 = 0 4n2=25 n2=6.25 n=sqrt(6.25) n= +2.5 or -2.5
H2CN2 + heat --> N2 + CH2
6AG + N2 --> 2AG3N is the balanced equation.
N2 its an element in its natural state
n2 + 9n + 18 = (n + 6)(n + 3)
