The answer is C) [Ar]4s2 3d6
Answer:
0.80 seconds (2 significant figures)
Explanation:
The equation of the reaction is given as;
CICH2CH2Cl (g) --> CH2CHCI (g) + HCl(g)
Rate constant (k) = 2.01 s^-1
From the units of the rate constant, this is a first order reaction.
Initial Concentration = 1.34 M
t = ?
Final concentration = 20% of 1.34 = 0.268 M
The integrated rate law for a first order reaction is given as;
ln[A] = ln[A]o - kt
ln(0.268) = ln(1.34) - 2.01(t)
-2.01(t) = - 1.6094
t = 0.8007 ≈ 0.80 seconds (2 significant figures)
Answer:
option C
Explanation:
Metallic bonds exist in the atoms of metals. mobile electrons exist in metallic bonds and are referred as electron sea.This is the property that makes metals to have a high electrical conductivity.
Electrovalent and ionic bonds are formed when a metal loses an electron to a nonmetal. covalent bonds exists when electrons are shared between molecules of same elements or of different elements.
