Answer:
(V) 1s 2 2s 2 2p 6 3s 2 3p 5
Explanation:
Electron Affinity can be defined as the energy associated with a neutral atom, when an electron is added to form a negative ion.
1s 2 2s 2 2p 6 3s 2 3p 5 , is the electronic configuration of Chlorine.
The electron affinity is positive because it is an exorthermic reaction, meaning that, energy was released during the addition of an electron to the atom.
Cl (g) + e- -------> Cl- (g) = -349KJ/mol
Step-by-step explanation:
Cosx=sqrt3/2 and tanx=sqrt3/3
A Triangle has the same amount of points and sides, 3.
Answer:
Let x the number Mr John thinks
He double it so 2×x=2x ( double = multiplying by 2 )
The result is 58
So 2x=58
We solve the equation
2x=58
So x =58/2
x=19
So it's 19 the number Mr John thinks
Answer:f(x) indicates applying the function to the value x and can also represent the actual value obtained by applying the function to x
