Ionic Compounds
These kinds of bonds occur when nonmetal atoms share electrons to attain a noble gas arrangement.
What is a covalent bond?
A unit used count small particles such as atoms, molecules, and ions.
What is Avogadro's number?
This protein will increase the rate of a reaction and lowers activation energy.
What is an enzyme?
A concentration of a solution is expressed as this.
What is amount of solute over the amount of solution!
The two components of a solution.
What are solvents and solutes?
Metals that lose valence electrons to form ions with a positive charge.
What is a cation?
This portion of a formula shows the relationship of atoms and the moles of each element in 1 mole of compound.
What are the subscripts in a formula?
During this process heat is absorbed as a reactant.
What is an endothermic reaction?
Molarity of a concentration is expressed as this.
What is moles of solute over liters of solution?
These are spread evenly throughout the solution, can be separated by evaporation but not filtration, and are not visible.
What are solutes?
During naming of ionic compounds, these metals have a variable charge.
What are transition metals?
A unit expressed in grams that is the atomic weight of an element.
What are moles?
The strongest force between molecules are caused by this type of bond.
What are hydrogen bonds?
The process of adding water to reduce the solute concentration.
What is dilution?
Molecules that can form solutions that conduct an electric current.
What is a Strong electrolyte?
The name of the polyatomic ion NH4+
The numbers that precede a chemical formula in an equation that shows the number of atoms, molecules, or formula units of that substance involved.
What are coefficients?
This law states as the temperature of gas increases, the pressure of the gas increases.
What is Gay-Lussac's law?
Volume and concentration are related by this type of proportion.
What is an inverse proportion?
The maximum amount of solute that dissolves in a specific amount of solvent.
What is solubility?
Ions made up of more than one atom, usually consisting of nonmetals such as P, S, C, N, or O.
What are polyatomic ions!
A process that involves gaining electrons, losing oxygen, and gaining hydrogen.
What is a reduction?
During this process the diaphragm contracts and the rib cage expands.
What is inspiration?
A concentrated solution of a known concentration that will be diluted for use.
What is a stock solution?
The term that refers to reaching maximum solubility, causing additional solute to sink to the bottom.
What is a saturated solution?
