Answer:
The given statement is false.
Explanation:
Ionic bond is formed by strong electrostatic attraction between two atoms having large difference in their electronegativity.This strong electrostatic attraction provide structural stability to the ionic compounds.For example NaCl.
The ionic compounds generally are solid in nature.As a result their melting point and boiling point are higher that covalent compounds as covalent compounds exist in liquid of gaseous state.
The total mass of magnesium chloride is 95.21g/mol
The mass of chlorine is 35.45g/mol
To find the mass percent of chlorine, divide its molar mass by the total mass of the substance and multiply the result by 100:
(35.45/95.21)(100)= 37.2%
B, more kinetic energy means more collisions and thus more reactions according to collision theory.
The standard cell potential of a cell made of theoretical metals ma/ma2+ and mb/mb2+ is to be determined. We are given their reduction potentials:
-0.19 v for A
-0.85 v for B
To solve for the standard cell potential, examine the reaction and
the standard cell potential for this case is (-0.19- (-0.85)) v = -0.66 v<span />
