100
Heat is released when a cation binds to this type of ion.
What is an anion?
100
The proper name of this molecule is NOT dihydrogen monoxide.
What is water?
100
These two particles give an atom almost all of its mass.
What are protons and neutrons?
100
An alkaline earth metal forms this type of ion.
What is a cation (or a 2+ ion)?
100
Electrons are shared in this type of intramolecular bond.
What is a covalent bond?
200
23 degrees Celsius is this many Kelvin.
What is 296 K?
200
What is the shape of a p orbital?
What is a dumb bell shape?
200
6.022 x 10^23
What is Avogadro's Number? (or a mole?)
200
This type of covalent bond is shorter and stronger than a double bond.
What is a triple bond?
200
The maximum number of valence electrons in a period 2 atom.
What is 8?
300
This period 2 element is capable of participating in hydrogen bonds and has a smaller atomic radius than oxygen.
What is fluorine?
300
Only this type of bond is broken during a phase change.
What are intermolecular bonds?
300
The molecular geometry of ammonia.
What is trigonal pyramidal?
300
The correct Lewis structure of a sulfide anion has this many valence electrons.
What is 8?
300
This element, with a valence shell at energy level n = 6, reacts with chlorine (Cl) in the same way as calcium (Ca).
What is barium (Ba)?
400
This element with a valence of 6 has a lower electronegativity than fluorine (F) and a higher electronegativity than arsenic (As), and it is normally found as a diatomic gas.
What is oxygen (O)?
400
One mole of gas, which occupies 22.4 L at standard temperature and pressure, occupies this volume when the temperature is reduced to 36.5625 K.
What is 3 L?
400
2 L of a 6 M solution is diluted to a final volume of 3 L, yielding a solution of this concentration.
What is 4 M?
400
This ion has the same valence shell configuration as neon (Ne) and has a 3rd ionization energy that is much higher than the 2nd.
What is magnesium (Mg)?
400
When the alkali metal potassium (K) reacts explosively with water to form potassium hydroxide and hydrogen gas, this is the reducing agent.
What is potassium?
500
This is the molecular mass (in amu) of a water molecule containing an isotope of oxygen with two more neutrons than the most common isotope.
What is 20 amu?
500
The pH of a 0.001 M solution of HCl (hydrochloric acid).
What is 3?
500
When a flame is applied to a sealed reaction vessel containing an exothermic reaction at equilibrium, Le Chatelier's Principle predicts that the rate of the formation of products will temporarily have this comparative relationship to the rate of the formation of reactants.
What is "less than"?
500
The mass (in grams) of 2.5 x 10^(-1) mol of carbon dioxide.
What is 11 g?
500
