Solutions and Electrolytes
This term describes a homogeneous mixture of two or more substances
What is a solution
Energy associated with motion is known by this name.
This Greek letter, lambda, stands for the distance between successive wave crests.
What is wavelength?
This term describes an insoluble solid that forms when aqueous solutions react.
What is a precipitate?
The specific part of the universe under study is called this.
What is the system?
In saltwater, water plays this role because it is the dissolving medium and present in the largest amount.
What is the solvent?
Energy stored due to position or chemical arrangement has this name.
What is potential energy?
This quantity counts the number of waves passing a point per second.
What is frequency?
These ions remain unchanged on both sides of a complete ionic equation.
What are spectator ions?
Everything outside the system is called this.
What are the surroundings?
A dissolved substance that makes a solution conduct electricity is called this.
What is an electrolyte?
The random motion of atoms and molecules is associated with this form of energy.
What is thermal energy?
The relationship between speed of light, wavelength, and frequency is expressed by this equation.
What is c = lambda*frequency(v)
This equation type omits spectator ions to show only species involved in the reaction.
What is a net ionic equation?
This symbol represents the change in internal energy in the equation deltaU = q + w.
Water-soluble ionic compounds belong to this class of electrolytes because they dissociate completely.
What are strong electrolytes?
This law states that energy can be converted but cannot be created or destroyed.
What is the law of conservation of energy?
If wavelength increases for light in a vacuum, frequency changes in this direction.
What is decreases?
According to common solubility rules, salts containing this polyatomic ion, NO3-, are soluble.
What is nitrate?
Under the chemistry sign convention, heat absorbed by the system has this sign.
What is positive (+)?
Unlike HCl, acetic acid ionized only partly in water and is classified this way.
What is a weak electrolyte (or weak acid)?
A food Calorie equals this number of Joules.
What is 4,184 J (or 4.184 kJ)
Among visible red and violet light, this color has the shorter wavelength.
What is violet?
Mixing AgNO3(aq) and NaCl(aq) produces this insoluble solid.
What is AgCl(s), silver chloride?
If q = +80 J and w = -30 J, the change in internal energy is this.
What is +50 J?
