Q: Answer the following question given this paragraph: Metals such as iron are useful for many purposes because of their unique properties. For example, they can conduct electricity and bend without breaking. However, pure metals may be less useful than mixtures of metals with other elements. For example, adding a little carbon to iron makes it much stronger. This mixture is called steel. Steel is so strong that it can hold up huge bridges, like the one pictured above. Steel is also used to make skyscrapers, cargo ships, cars, and trains. Steel is an example of an alloy. Q: Adding carbon to iron makes what type of metal? A:
Answer: steel

Answer the following question given this paragraph: Thus the potential of a galvanic cell can be used to measure the pH of a solution. Exercise Suppose you work for an environmental laboratory and you want to use an electrochemical method to measure the concentration of Pb2+ in groundwater. You construct a galvanic cell using a standard oxygen electrode in one compartment (Ecathode = 1.23 V). The other compartment contains a strip of lead in a sample of groundwater to which you have added sufficient acetic acid, a weak organic acid, to ensure electrical conductivity. The cell diagram is as follows". Q: The potential of what can be used to measure the ph of a solution? A:
****
A: galvanic cell

Answer the following question given this paragraph: Eris is the largest known dwarf planet in the solar system. It is 27 percent larger than Pluto ( Figure above ). Like Pluto and Makemake, Eris is in the Kuiper belt. But Eris is about 3 times farther from the Sun than Pluto. Because of its distance, Eris was not discovered until 2005. Early on, it was thought that Eris might be the tenth planet. Its discovery helped astronomers realize that they needed a new definition of "planet. " Eris has a small moon, Dysnomia. Its moon orbits Eris once about every 16 days. Q: What are small planets in our solar system called? A:
OPTIONS:
- scrub planets
- Tiny planets
- light planets
- dwarf planets

Answer:
dwarf planets
