Read the scenario below. Then determine what happened to the motion of the molecules for some of the objects that are mentioned. While on vacation, Carly and her family went hiking. Carly knew it was going to be hot that day, so she brought a water bottle. She filled the bottle with water and also added some ice cubes. Carly was happy to find that the water was cold when she stopped to take a drink. She also noticed that a lot of the ice had melted.
After hiking for a few hours, her family decided it was time for dinner and her parents made a fire so that they could cook food. Her dad carefully placed a pot over the flame and filled the pot with beans. Carly put a hot dog on a metal skewer and began to heat the hot dog over the fire. At this point in the evening, the temperature outside became cooler. Carly's mother made her a cup of hot chocolate before going to bed. Carly was so interested in exploring the campgrounds with her brother that she forgot about the hot chocolate. When she came back to her campsite, the hot chocolate was cold but she decided to drink it anyway.

Which substances have the lowest melting points: ionic covalent, or metallic

An atom of sodium-23 (atomic number = 11) has a positive charge of +1. give this information, how many electrons does it have? how many proteins and neutrons does this atom have

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely.analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?
