Geologic Illustrations. A map shows a bird's eye view looking down at the earth's surface. ... Often a geologic map will indicate both the type of rock and the age of the rock. A cross section shows the surface of the earth (with or without topography or elevation) and a vertical slice of the earth
Answer:
c. electrons of the transition metal ion are excited to higher energies.
Explanation:
answer of this question is [Ar]3d8 4s2
Answer:
The concentration of H3O+= 0.15M
Explanation:
From The equation of reaction
HClO2(aq) + H2O(l) ⇌ H3O+(aq) + ClO2−(aq)
0.25mol HClO2(aq) 0.25mol producesClO2−(aq) and x-mol of H3O+
Using Kc = [H3O+][ClO2-]/[HClO2]
0.15= 0.25*x/0.25
Simplify
x=0.15M
Answer:
Covalent bond
ionic bond
Explanation:
Water molecule is formed when two hydrogen atoms combine with one atom of oxygen. The bond through which these atoms are join together is called covalent bond.
The electrons are shared between these atoms but this sharing is not equal. the oxygen atom more strongly pull the electrons to wards itself and thus carry partial negative charge and hydrogen have partial positive charge.
Ionic bond:
The bond between sodium chloride is ionic. This bond is formed due to complete transfer of electron from sodium to chlorine.
Na⁺Cl⁻
The sodium atom carry positive charge and chlorine carry negative charge.
