Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
<span>After many experiments and many different approaches to the question, the scientist may be able to develop a theory. The theory explains why nature behaves in the way described by the natural law. It answers not only the original question, but also any other questions that were raised during the process. The theory also predicts the results of further experiments, which is how it is checked. Theories are not the end of the process.</span>
The statements that are true regarding a catalyst are as follows:
It undergoes no permanent change during a reaction
It does not participate in a chemical reaction
What is a catalyst?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
A catalyst increases the rate at which a chemical reaction occurs by decreasing the activation energy of the reaction.
Since a catalyst is not used up in the reaction, the following statement applies:
It undergoes no permanent change during a reaction
It does not participate in a chemical reaction

You can use a fan on the wire. That's one way.
