Knowing how important the brain is to the functioning of all of our body functions, what do you think happens if one of these lobes is injured? what body functions could be affected, depending on which lobe of the brain is affected? many sports involve frequent head injuries. do you know of any such cases? discuss such an event and how it could have been avoided. how should people and athletes protect themselves from brain injury?

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.

idk what is it? is this a question that you know the answer or u dont
