Ionic Compounds
What type of ion does a lithium atom form?
Li+ is formed and, which is a plus 1 ion
What are the contents of a covalent compound?
Illustrate the chemical equation: Iron (III) + Oxygen -> Iron (III) oxide
Fe + O2 -> Fe2O3
Name 3 of the 7 diatomic elements
Any 3 of Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, and Chlorine
What is the molar mass of Au(OH)3?
248g
What type of ion is formed by metals and nonmetals, and what is the difference between the two?
Metals form cations because they lose electrons to become stable, and nonmetals form cations because they gain electrons.
State the name for As2O3
Diarsenic trioxide
The fact that chemical equations must be balanced is emphasized in what principle?
The Law of Conservation of Mass
What type of chemical reaction takes place in the equation C6H14+O2->CO2+H2O
Combustion reaction
What is the molar mass of NF3?
41.01g
What is the formula for aluminum sulfide?
Al2S3
How many of each element's atoms are present in one molecule of C2H5OH(Ethanol)?
2 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom.
Predict what type of chemical reaction will occur in the equation AgNO3 + NaCl.
Double replacement
Analyze the chemical equation KOH + H3PO4 = H2O + K3PO4 and determine what coefficient is present in front of KOH
3
What is the name for the compound Ni2S3?
Nickel (III) sulfide
Predict what would be produced when placing a NaCl compound into a beaker of water.
Electricity would be produced
Predict what type of bond would be present in the compound C2H2 (Acetylene) between the two carbon atoms, and explain what this does to the compound.
A triple bond would be present between the two carbon atoms, which causes C2H2 to be unsaturated.
Determine whether a reaction will take place, and explain why/why not: Mg3(PO4)2 + Pt
No reaction (NR) will occur because Platinum(Pt) is less reactive than Magnesium(Mg), therefore, cannot replace it.
Balance the following equation: __ TiCl4 + __ H2O → __ TiO2 + __ HCl
1 TiCl4 + 2 H2O → 1 TiO2 + 4 HCl
Predict the the products given the reactants: BaCl2+Na2SO4
Ba(SO4)+2NaCl
How would the compound ammonium dichromate's formula be written?
(NH4)2Cr2O7
COCl2 would make a trigonal planar shape, and there is a double bond between the carbon and oxygen, with single bonds to each chlorine.
Predict the products and balance the equation given the reactants: Ammonium permanganate + lithium hydroxide
NH4MnO4+LiOH->NH3+H2O+LiMnO4
Balance the equation using coefficients: _C5H8O2+_NaH+_HCl->_C5H12O2+_NaCl
C5H8O2+2NaH+2HCl->C5H12O2+2NaCl (1,2,2,1,2)
Why do ionic compounds usually have very high melting points?
The electrostatic forces between the ions are very strong and take a high amount of energy to break (high temperature)
