Write the formula
Which character in "Spongebob" was out to get the Krabby Patty formula (recipe)?
Plankton
S4O6
tetrasulfur hexoxide
Is sodium oxide an ionic or covalent compound and how do you know?
Ionic - metal + nonmetal or name does not have prefixes
Which singer sings the song "Shape of You"?
Ed Sheeran
Darth Vader uses "The Force". What is the name of the actor that voiced Darth Vader in "Star Wars"?
James Earl Jones
Dicarbon trioxide
C2O3
What is the name of author who wrote "The Great Gatsby"?
F. Scott Fitzgerald
Explain why the compound "copper nitrate" is not the name of a compound? Hint: try writing the formula for it to find out what is wrong.
What shape is SF2
Bent
Is CNF polar or nonpolar and explain your reasoning?
Polar because the pull from fluorine on carbon is more than the pull on nitrogen so they do not cancel out
Sodium nitride
Na3N
Aluminum chloride
Which two countries are "bonded" because they share the longest border in the world?
US and Canada
What shape is SiSO?
Linear
Is CF4 polar or nonpolar? Explain your reasoning.
Nonpolar - even though each bond is polar, the molecule is symmetrical so the pull from each fluorine cancels out.
Iron (II) acetate
Fe(C2H3O2)2
OR Fe(CH3COO)2
CrCO3
Chromium (II) carbonate
You are trying to determine the type of bond in an unknown substance. You find it has a low melting point, dissolves in water, and does not conduct electricity. What type of bond does the compound contain: nonpolar covalent, polar covalent, or ionic?
Polar Covalent
What shape is NH2Cl?
Trigonal pyramidal
State the type of intermolecular force that would occur between CH3Cl and H2S. Then state whether these compound would be miscible or immiscible.
dipole-dipole forces
Miscible (both polar)
Ammonium thiosulfate
(NH4)2S2O3
Cu3PO4
copper (I) phosphate
Explain the relationship the difference between polar covalent bonds and ionic bonds in terms of electronegativity and what is happening between the electrons of the bond.
Polar covalent - there is an electronegativity difference between the atoms that are sharing electrons so the electrons are not shared equally (the one with higher eneg pulls electrons towards itself).
Ionic - the electronegativity between the atoms is SO big that the more eneg atom completely steals an electron from the other atom (transfer of electrons)
What shape is CH2S?
Trigonal Planar
Which compound would have the greatest surface tension and why?
SiF4 OR NH3 OR CH3Cl
NH3 is most polar and can have hydrogen bonding forces. Therefore it has the strongest forces between molecules which would make it difficult to break the surface resulting in a higher surface tension.
