Write a summary paragraph commenting upon the common ion effect and its influence on solubility, and commenting upon activity effects and their influence on the Ksp value.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

it's c. elements are placed in rows based on how may valencies electrons have.

10 years is the answer

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.
