Describing types of chemical bonds Match each bond with the rearrangement of the valance electrons needed to form that bond metallic bond ionic bond covalent bond sharing of electrons sharing of many electrons transferring of electrons

metallic bond —> sharing of many electrons

covalent bond —> sharing of electrons

ionic bond —> transferring of electrons

Explanation:

im not 100% sure this is right but i hope it still helps!

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.
