After the flip, the volume axis will be lined up end-to-end with the zero values superimposed. you should now have a curve that looks like an "s" lying on its side and one of the graphs will be face down. hopefully your graph paper is "see through." find the ph range over which the buffer effectively neutralizes the added strong acid and strong base and maintains a reasonably constant ph. this is referred to as the buffer range. to which of the following ranges is the buffer range of the acidic buffer closest?

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

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.
