It's a simple riddle with numbers.
The answer to the riddle is n=7 .
n = +5 or -5
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
If: n2 = 19 Then: n = the square root of 19.
N2
so 3n2 = 15 ie n2 = 5 so n = sqrt 5
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 + 9n + 18 = (n + 6)(n + 3)
N2 its an element in its natural state
The balanced equation for the reaction of hydrogen gas (H2) with nitrogen gas (N2) to form ammonia (NH3) is: 3H2 + N2 → 2NH3
-5
To balance the chemical equation N2 + O2 = N2O5, start by counting the atoms of each element on both sides. You would need to put a coefficient of 2 in front of N2 to balance the nitrogen atoms. Then, add a coefficient of 5 in front of O2 to balance the oxygen atoms. The balanced equation is 2N2 + 5O2 = 2N2O5.
