Plz answer as fast as you cansolid sodium iodide does not conduct electricity
why does sodium iodide solution conduct electricity


2) when sodium iodide is electrolysed iodine is formed at the positive electrode
complete and balance the half equation for the formation of iodine
........ I- = I2 + ........ e-

3) what is formed at the negative electrode when sodium iodide solution is electrolysed
explain why

Answers

Answer 1
Answer: the solution conducts electricity because it has free delocalized which are free to move.

What causes matter to exist in three different states​

Answers

NOT 100% SURE

Thermal Energy..?

When I think of three states of matter I think of water as an example:

• Adding extreme heat to the liquid form of water can turn it into gas.

• Adding heat to ice can turn it into the liquid form of water.

• Freezing the liquid form of water can turn it into ice.

I would say temperature (thermal energy) has an effect of the different states of matter.

Changing the number of protons in an atom makes

A. an ion
B. an isotope

Answers

A. an ion

The atom gains a net electrical charge if the number of protons and electrons are not equal which makes it an ion.
