[If you're within 0.1 on either side, you still get the point.]
300
This is the opposite of synthesis (aka. combination).
What is decomposition?
300
The difference between a molceule and a crystal?
What is, "the molecule is made of nonmetals only, and the crystal is metal and nonmetal"
or "Molecular compounds engage in covalent bonding, and crystals engage in ionic bonding."
300
Strontium and barium have similar chemical properties because atoms of these elements have the same number of...
What is "valence electrons"?
400
This is the formula unit for lithium sulfide.
What is Li2S?
400
True or False: All atoms are trying to reach the stable octet.
What is False?
(Ex: duet rule with the elements Helium and Hydrogen)
400
If the EN difference in a bond is classified as less than 0.4 (usually, it's a value of 0), then this is what the bond can be classified as.
What is a nonpolar bond?
OR what is a nonpolar covalent bond?
400
This type of reaction requires an element & (separate from that element) a compound on the left side of the arrow, as well as a full reactionary exchange between the lone element and one of the elements in the compound.
What is single replacement?
400
The molecular formula for ammonia is NH3(g), is a compound that is used to manufacture fertilizer for agriculture. This is the number of electrons shared between the nitrogen atom and one of the hydrogen atoms in an ammonia molecule.
