Q5.6. if calcium ions, each of which has a charge of +2 (ca2+), moved out of a neuron, and no other ions were moving, what would be true?

Each calcium ion has a charge of +2, which can also be written as ca2+. if those ions move out of the neuron and no other ions are moving, the neuron would lose the positive charge associated with those ions and become more negatively charged.

The answer is c) pyrite
