What is PPM in full
PPM = Parts Per Million.
1 ppm = 0.0001%
What kind of solid breaks with no regular patterns
What kind of crystalline solid is MgCl2
What two factors determine the point at which a liquid will boil
Heat or energy applied and atmosphereic pressures
Pressure and temperature (apex)
Which of the following best describes the kinetic theory
Atoms and molecules are always moving or vibrating.
What temperature scale is used in the ideal gas equation
Which type of molecules would have the lowest melting point
What is the freezing point of sea water and pure water
The freezing point of pure water is 0 0C.
The freezing point of sea water is variable, depending on the
amount of dissolved salts (approx. -3 0C).
According to the ideal gas law what happens to the volume of a gas when the number of moles doubles
What is the following of a base
A base contain the hydroxyl group (OH)-.
What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg
Molality (m) is defined as moles of solute per kg of
solvent.Thus, 2 moles/6 kg = 0.33 molal or 0.3 m.
What will result from increasing the temperature of gas
Increasing the temperature of gas the volume increase.
Which of the following is an electrolyte solution
The answer is "Ions in water" on Apex
