SO2 reacts with H2S as follows: 2H2S + SO2 --> 35 + 2H2O When 7.50 g of H2S reacts with 12.75 g of SO2, which statement is true?
A. 0.221 moles of SO2 is consumed
OB. 0.266 moles of SO2 is consumed
C. 0.442 moles of SO2 is consumed
D.0.111 moles of SO2 is consumed

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.
