Question You are given a mixture of napthalene, magnesium chloride and barium hydroxide. You know this about the components: ) Napthalene has a low boiling point and does not dissolve in water )Magnesium Chloride has a high boiling point and does dissolve in water ) Barium hydroxide is basic and does not dissolve in waterDescribe a process that would allow you to separate and weigh each component of this mixture
Is this machine in transmission mode or atr mode? I think it is in
Question Is this machine in transmission mode or atr mode? I think it is in transmission mode due to the center piece being upright and the fact that atr mode does not require much assistance from what I have learned. But this looks like a card, so I am not sure
