A student claims that solid KCl conducts electricity better than KCl dissolved in water. Which statement best evaluates this claim?
The claim is true because solid KCl contains free electrons
The claim is true because ions move freely in solids
The claim is false because ions are fixed in a solid but free to move in solution
The claim is false because covalent bonds prevent conductivity
Which bond is nonpolar because the atoms share electrons equally?
H–Cl
O–H
S–S
N–H
Which bond is polar because electrons are shared unequally?
Cl–Cl
O–O
H–I
N–N
A student claims that the bond between NaCl is polar because it is between two different elements. Evaluate this claim
The claim is correct because all bonds between different elements are polar.
The claim is correct because sodium and chlorine share electrons unequally.
The claim is incorrect because sodium and chlorine form an ionic bond (Metal and nonmetal)
The claim is incorrect because NaCl contains only nonpolar covalent bonds.
