- Red-Eared Sliders are illegal in California true or false?Vacuum filtration is just one method that can be used to separate the components of a mixture. Describe another method for separating the components of a mixture, and comment on how "green" the method is. Be sure to indicate the physical state of each component during separation. Scientific literature should be cited as part of your response.When working with volatile chemicals, such as flammable solvents the best way to control exposures is to: A. Work on the open benchtop as laboratory ventilation is sufficient to remove vaporsB. Work in a chemical exhaust hood (fume hood) as it provides vapor and splash protection when the sash is in the proper positionC. Conduct all of your work outdoorsD. It doesn't really matter where you work because most exposures are insignificant
