A scientist is conducting an experiment to determine the melting point of a substance. They find that the melting point is about 160 0C higher than they expected based on the size and molecular mass of the compound. What would explain their results? Select all correct answers. a. The substance is nonpolar, so London dispersion forces exist
b. Dipole-induced dipole attractions strongly hold the molecules together
c. Temporary dipole-induced attractions form in the solid where it melts
d. The substance is strongly polar, so dipole-dipole attractions exist
e. Hydrogen bonding strongly holds the molecules together in the solid state

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.

it's c (engineer's do their work with mechanical stuff not on any living being)

the answer is 0.42 is that is an option. this question provides no info
