Answer:
A(l)→A(aq) - Nonelectrolyte
BC(aq)⇌ B+(aq)+C−(aq) - Weak electrolyte
DE(aq)→D+(aq)+E−(aq) - Strong electrolyte
XY(s)→X+(aq)+Y−(aq) - Strong electrolyte
Z(s)→Z(aq) - Nonelectrolyte
Step-by-step explanation:
An electrolyte that, when dissolved in water, allows the water to conduct electricity. Electrolytes are ionic compounds that dissociate into their constituent ions when dissolved in water. Strong electrolytes dissociate completely while weak electrolytes do not dissociate completely. A nonelectrolyte does not allow water to conduct electricity and does not break apart when dissolved in water.
A and Z are nonelectrolytes since they do not separate into a positive and negative part when dissolved in water
BC, DE, and XY are electrolytes since they dissociate into their constituent ions when dissolved in water. BC is a weak electrolyte since the ions are in equilibrium with the compound BC, meaning that BC doesn't dissociate completely. DE and XY are strong electrolytes since they dissociate completely as indicated by the forward arrow.
