Law of Conservation (SPS3)
This law states that matter cannot be created or destroyed in a chemical reaction.
Law of Conservation of Matter
The phase of matter where particles are tightly packed and only vibrate in fixed positions.
Solid
This gas law describes the direct relationship between temperature and pressure when volume is constant.
Gay-Lussac’s Law
The part of a solution that is being dissolved (usually the smaller amount).
Solute
A solution with a pH of 7 is considered this.
Neutral
These are the starting "ingredients" on the left side of a chemical equation.
Reactants
The process of a gas turning into a liquid, represented by a flat line on a cooling curve.
Condensation
According to Boyle’s Law, if the pressure of a gas increases at a constant temperature, this happens to its volume.
Volume decreases (Indirect relationship)
A solution that can conduct electricity because it contains dissolved ions.
Electrolyte
This type of substance tastes sour and turns blue litmus paper red.
Acid
Balance this: N2 + H2 -> NH3 (State the coefficients in order).
1,3,2
This high-energy phase of matter consists of ionized gas found in stars.
Plasma
This factor measures the average kinetic energy of the particles in a substance.
Temperature
Three ways to increase the rate at which a solid solute dissolves in a liquid.
Stirring (Agitation), Increasing Temperature, and Crushing (Increasing Surface Area)
These ions are released by bases when they dissolve in water.
Hydroxide ions (OH-)
Identify this reaction type: AgNO3 + Cu -> Cu(NO3)2 + Ag.
Single Replacement
During a phase change, the temperature stays the same because energy is being used to break these.
Molecular bonds
When gas is heated, its molecules move faster and further apart, causing this property to decrease.
Density
A solution that contains the maximum amount of solute that can be dissolved at a given temperature.
Saturated
This common household base is often used in baking and to neutralize small acid spills.
Baking Soda
If 16g of CH4 reacts with 64g of O2 to produce 44g of CO2, how many grams of H2O are produced?.
36g (Reactants 16g+64g=80g Total mass 80g - 44g of CO2 = 36g of H2O)
On a heating curve, this specific plateau represents the change from a solid to a liquid.
Melting Point
Explain why a car's tire pressure might appear lower on a very cold morning.
As temperature decreases, gas molecules move slower and take up less space (volume decreases), which lowers the pressure.
This term describes the amount of solute dissolved in a specific volume of solvent.
Concentration
These are the two products typically formed when an acid and a base react (neutralization).
A salt and water
