Front

What is the molar mass of fluorine gas?

Back

The molar mass of fluorine gas (F2) is 38 g/mol.

Front

As temperature increases, what happens to particles?

Back

As temperature increases, particles speed up.

Front

Which one of the following would you use to separate sand from iron filings?

Back

A bar magnet can be used to separate sand from iron filings.

Front

When the solution equilibrium point is reached and no more solute will dissolve, the solution is said to be _________.

Back

The solution is said to be saturated.

Front

What is the number of protons that the element in this image contain?

Back

The element contains 7 protons.

Front

Define molar mass.

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is the principle behind using a bar magnet to separate mixtures?

Back

The principle is based on magnetism; iron filings are attracted to the magnet while sand is not.

Front

Explain the concept of saturation in solutions.

Back

Saturation occurs when a solution can no longer dissolve additional solute at a given temperature and pressure.

Front

What happens to the kinetic energy of particles as temperature increases?

Back

The kinetic energy of particles increases as temperature increases.

Front

What is the difference between unsaturated and supersaturated solutions?

Back

An unsaturated solution can dissolve more solute, while a supersaturated solution contains more solute than can normally dissolve at that temperature.
