Consider the following molecules with trigonal planar geometry. Carbonate (CO32− C O 3 2 − ) and nitrate (NO3− N O 3 − ) both exhibit resonance, whereas phosgene (COCl2 C O C l 2 ) does not. Given the information in the transition, and ignoring the simulation, predict the bond angles for each of the molecules in accordance to whether or not they exhibit resonance.

the temperature of the gas, in k, not celsius.

the answer would be a

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.
