input: OPTIONS:
- lead and steel
- lead and sodium
- steel and sodium
- lead and plastic Now, answer this question: Answer the following question given this paragraph: Lead is still widely used in car batteries. In recent years, battery recycling is becoming very common - about 98% of car batteries a recycled today. The used batteries go to a processing plant where they are crushed and placed in a tank. The lead sinks to the bottom and can be separated, melted and used again. Plastic materials float to the top, are separated, and melted. The plastic can then be used in a number of applications. The battery acids are treated with chemicals to neutralize them before they are disposed of. Q: What substances in a car battery can be melted and recycled? A:
A:
output: lead and plastic

- bonding pairs
Q: Answer the following question given this paragraph: The water molecule, like the ammonia and methane molecules, has a tetrahedral domain geometry. In the water molecule, two of the electron pairs are lone pairs rather than bonding pairs. The molecular geometry of the water molecule is referred to as bent . The H-O-H bond angle is 104.5, which is smaller than the bond angle in NH 3 . Q: In the water molecule, two of the electron pairs are lone pairs rather than what? A:
Answer: bonding pairs

Problem:OPTIONS:
- Simple
- unicellular
- monophyletic
- prokaryotic

****
A: prokaryotic

Answer the following question given this paragraph: An n-type (negative-type) semiconductor consists of silicon and an element such as phosphorus that gives the silicon crystal extra electrons. You can see this in the Figure above . An n-type semiconductor is like the negative terminal of a battery. Q: Silicon with an element that gives it extra electrons is which type of semiconductor? A:
OPTIONS:
- m. Type
- i.g - type
- k. - type
- n-type
n-type

Answer the following question given this paragraph: A common method of producing charge in the lab is to rub cat or rabbit fur against stiff rubber, producing a negative charge on the rubber rod. If you hold a rubber rod on one end and rub only the tip of the other end with a fur, you will find that only the tip becomes charged. The electrons you add to the tip of the rod remain where you put them instead of moving around on the rod. Rubber is an insulator. Insulators are substances that do not allow electrons to move through them. Glass, dry wood, most plastics, cloth, and dry air are common insulators. Materials that allow electrons to flow freely are called conductors. Metals have at least one electron that can move around freely, and all metals are conductors. Q: Rubber is an example of what type of substances that do not allow electrons to move through them? A:
OPTIONS:
- conductor
- semi-conductor
- solids
- insulators

Answer:
insulators
