You are talking with your friend when all of a sudden a huge lightning storm starts. You and your friend are both amazed by the lightning show.
All of sudden you happen to witness lightning striking the ground. Your
friend says "Wow, that was amazing. We should rush outside to the spot
that the lightning just struck because "lightning never strikes the same
place twice". Now since you are taking Mr De Thomasis class, you know
that although this is a logical statement, it is not necessarily true. Please
explain to your friend why lightning can in fact strike the same place twice.
In your answer. Please include the steps needed to get lightning, as well as
Provide an explanation to correct your friend.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

i think its 100

i hope this !
