Which statement compares the attractive forces that hold particles together? A. Metallic and covalent bonds are weakly attractive; hydrogen
bonding and Van der Waals forces are strongly attractive.
B. Covalent bonding and Van der Waals forces join molecules
together; ionic and hydrogen bonding produce compounds.
O c. Metallic bonds and Van der Waals forces are weakly attractive;
covalent and hydrogen bonds are strongly attractive.
D. Metallic and covalent bonds are strongly attractive; hydrogen
bonding and Van der Waals forces are weakly attractive.

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.
