What number is most likely to be expressed in scientific notation

A given mass of air has a volume of 6.00 L at 101 kPa. At constant temperature, the pressure is decreased to 25.0 kPa. Calculate the final volume for the gas, as described by Boyle's law.

In many of the steps in the lab, a mixture was centrifuged and then decanted. In general terms, what is accomplished by these steps? In what kind of situation would these steps not be able to separate two compounds?

A bucket of water with dry ice is not making fog fast enough. As a special effects expert, how could you make the fog form faster in the bucket?

The anion formed from an oxygen atom is called a (n) a. oxygen ion. c. carbon dioxide. b. oxide ion. d. nitrous oxide.

These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a distance between the nucleus and the valence electron shell, which increases the attraction between the protons and electrons.

Given Mg (CO3) 2, CO2 and Cu3 (PO4) 2, provide the names for each of these molecules.

How does probability fit into the description of the atom?
