Answer:
A family is a vertical column .
The elements in a family have similar chemical properties.
Answer:
Electronegativity difference between 2 atoms
Explanation:
1. If the electronegativity difference (usually called ΔEN) is less than 0.5, then the bond is nonpolar covalent.
2. If the ΔEN is between 0.5 and 1.6, the bond is considered polar covalent
3. If the ΔEN is greater than 2.0, then the bond is ionic.
A. Atomic radius increases
Answer:
-184.6 KJ/mole
Explanation:
H2(g) + Cl2(g) ------------> 2HCl(aq)
Δ H0 rxn = Δ H0f products - Δ H0f reactants
= 2×-92.3 - (0 + 0)
= -184.6KJ/mole
H2(g) + Cl2(g) ------------> 2HCl(aq) Δ H0rxn = -184.6KJ/mole
<span>Conductance gives a more accurate method to determine the salt concentration of a solution.Conductivity would be used with conductors such as metals that include copper and silver.Conductivity is a measure of water's capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds</span>
