Atoms
The particles that are represented by the dots in Lewis valence e-dot structures.
What are valence electrons?
The formula for sodium chloride.
What is NaCl?
A reaction involving elements "switching places"
What is a replacement reaction?
A type of reaction when energy is absorbed.
What is endothermic?
A mixture that is unevenly mixed throughout
What is a heterogeneous mixture?
The movement of particles as temperature increases.
What is faster?
Bonding that occurs between two nonmetals.
What is covalent bonding?
The reactant that "runs out first"
What is the limiting reactant?
In this type of reaction, the ΔH° is positive.
What is endothermic?
As average kinetic energy increases, this also increases.
What is the movement of particles?
The subatomic particle that identifies the type of element.
What is the proton?
What is NaOH?
The Law that describes why chemical reactions must be balanced.
What is the law of conservation of mass/matter?
The science of calculating the heat of chemical reactions and physical changes
What is calorimetry?
This trend increases going down the periodic table.
What is atomic radius?
This model shows the electrons sitting in energy shells or levels.
What is the Bohr Model?
What are two valence electrons?
The coefficients be for the following equation:
KClO3→ KCl + O2
What is 2, 2, 3?
To make a 4 cup pot of green tea, one must heat the water to the boiling point (100°C). If the pot contains 680 grams of water, and the INITIAL temperature at the tap is 20.0°C, how much heat must be absorbed by the water? (Use 4.18 J/g °C for the specific heat of water.)
What is
Volume does this when pressure is increased.
What is decreasing?
The name of an element that has lost or gain electrons.
What is an ion?
Having a partial charge on each side of its molecules.
What is polarity?
The amount in grams of H2O needed to react with 50 grams of CH4 according to the following equation:
CH4 + 2O2 → CO2 + 2H2O
What is 112.5 grams?
How much ENERGY would be released when 50.00 grams of NH3 reacts with oxygen gas?
4NH3 + 5 O2→ 4 NO + 6 H2O ΔH = -1170. kJ
What is 860 kJ?
