7.3, 7.4, & Chapter 8 Flashcards
Will the compound FeCl3 dissolve in water? How can you tell?
Yes. Looking at the solubility chart on the periodic table, iron(III) chloride shows (aq), meaning that putting the compound in water results in an aqueous solution of it - it dissolves in water.
A solid that is produced as a result of a chemical reaction in solution and that separates from the solution.
Precipitate
Will the following reaction proceed as written? Explain.
Ca + Cu(NO3)2 –> Cu + Ca(NO3)2
Yes. Since calcium is above copper in the activity series, it will replace it.
A list of elements organized according to the ease with which the elements undergo certain chemical reactions.
Activity Series
Will the following reaction proceed as written? Explain.
AgBr + I2 –> AgI + Br2
No. Since the halogen iodine is below the halogen bromine on the periodic table, it is less active and will not replace it.
Will the compound MgO dissolve in water? How can you tell?
No. Looking at the solubility chart on the periodic table, magnesium oxide shows (s), meaning that, when placed in water, the compound remains solid - it does not dissolve.
Show the net ionic equation for the following reaction. You must first predict the products, balance the equation, and determine the solubilty of the products.
K2S (aq) + Zn(NO3)2 (aq) –>
A reaction in which a single compound produces two or more simpler substances:
AB –> A + B
ONLY ONE REACTANT

H2, N2, O2, F2, Cl2, Br2, I2
The separation of ions that occurs when an ionic compound dissolves.
Dissociation
Ions that do not take part in a chemical reaction and are found in solution both before and after the reaction.
Spectator ions
When balancing chemical equations, the only things that may be changed are the…
Coefficients
The symbols written after a substance in a chemical equation to indicate solid, liquid, gas, or aqueous, respectively.
(s), (l), (g), (aq)
When a solid is dissolved in water, it is this type of solution.
Aqueous
A chemical reaction in which the products re-form the original reactants.
A reversible reaction
