Answer:

First off, grab a simple magnet and hold it near your precious metal coin. If the coin is even slightly attracted to the magnet, then you know you have a fake on your hand, as metals with contents of iron and steel are the most likely to be attracted

A magnet will tell the difference if the coin is fake or not because is a coin is real it will stick and be magnetised to the magnet. If the coin is fake it will not stick, it will not magnetise, it means thay its fake.

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
IceJOKER [234]

Answer:

To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.

Explanation:

A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

What is the pH of a 0.00125 M HCl solution?
timofeeve [1]

Answer:

pH=2.9

Explanation:

Hello,

In this case, the pH is computed by:

pH=-log([H^+])

Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:

pH=-log(0.00125)\\\\pH=2.9

Regards.
