Answer:
Once you have collected 40 mL of distillate, you should ________.
turn off the hot plate and carefully lower the lab jack, making sure that no cords or hoses get caught in it.
Explanation:
Distillate is the product obtained from the process of distillation. Distillation is the separation of components of a liquid mixture based on different boiling points. Distillation can be used to purify alcohol, for desalination, refining of crude oil, and for obtaining liquefied gases. A lab jack is an essential tool that supports and lifts hotplates, glassware, baths, and other small lab equipment requiring stable surfaces at a specific height.
A metal that would be magnetic is nickel
Explanation:
require an emergency support immediately
CH₄ is a non-polar molecule, which means that it will contain only Van der Waals forces and induced dipole-dipole forces. These forces are weak, which is evident in the fact that methane is a gas at room temperature.
H₂O is a polar molecule, with hydrogen bonded to an electronegative atom, oxygen. This means that the forces present between water molecules are hydrogen bonding and dipole forces. These forces are comparatively strong, which results in water's liquid state at room temperature.
CO has dipole forces, which arise due to the difference in electronegativity between carbon and oxygen.
Chloromethane also possesses dipole forces for the same reason as CO does.
