Which of these would likely be the best conductor of electricity?rncacl2 (molten or dissolved)rnh2rnco2rnh2o
Accepted Answer
CaCl2 (molten or dissolved) would be the best conductor of electricity. Here's why:
Ionic Compounds: CaCl2 is an ionic compound, meaning it forms ions (charged particles) when dissolved or melted. These ions are free to move and carry electrical current.
Other Options:
H2: Hydrogen gas is a covalent molecule, with no free-moving charges. It's a poor conductor.
CO2: Carbon dioxide is also a covalent molecule and a poor conductor.
H2O: Pure water is a poor conductor, but adding ions like those from CaCl2 increases its conductivity.
