The process of passing a liquid through a porous substance to remove impurities is called: a) Decantation b) Filtration c) Distillation d) Adsorption

1. What is the functional purpose of an airbag?   The functional purpose of an airbag is to give a cushioned surface for the driver of a vehicle during the time of the collision. On page one, paragraph three, states, “They are designed to supplement seatbelt restraints and help to distribute the load exerted on a human body during an accident.” The airbag helps to absorb and distribute the force of the impact caused by the result of collision. Since the airbag is filled with a gas (N2) it can slow down the forward motion which can prevent someone from creating a sudden collision in the steering wheel with a greater force. It may also prevent the person inside from being thrown from the vehicle during a crash. Thus, the functional purpose of an airbag is to protect the driver from collision with the steering wheel by minimizing the force of impact.           2. While a series of events take place within the airbag system, what ultimately causes the airbag, stored in the steering column,…

Why do impure compounds normally have a lower melting point than the pure substance?

Two identical clear liquids were placed in separate containers labeled Sample A and Sample B. Both containers were left open until all the liquid evaporated in each. It was later observed that the container holding Sample A was empty. Meanwhile, white crystalline solids were found in the container of Sample B. Which of the following statements is FALSE about the given situation? Select one: a.The white crystalline solid is soluble in the liquid present in Sample B. b.Filtration can be used to separate the white crystalline solids in Sample B prior to evaporation. c.The absence of residue in Sample A after evaporation implies that it could be a pure substance. d.Sample A and Sample B both exist as one distinct phase before evaporation.

Please show your detailed solution. Note: the answer and the process should be in 4 decimal places.

Sodium formate is a white solid. Draw an atomic/molecular level picture to represent solid sodium formate. Sodium formate is soluble in water. Draw an atomic/molecular level picture to represent aqueous sodium formate.

One common problem with hard-boiled eggs is that their shells break in the water. Hard boiling eggs are best done by immersing them in cold water before bringing the water to a boil. What causes the shells to shatter in this situation? How can pin holing or needle piercing the shell preserve it from cracking? What else could cause the shells to crack?
