Naming
The ionic compound formed from Mg²⁺ and NO₃⁻.
What is magnesium nitrate?
A reaction in which two or more substances react to form a single product.
What is a synthesis (combination) reaction?
In a reaction where one reactant is completely consumed first, that reactant is called this.
What is the limiting reagent?
A property that can be observed without changing a substance’s identity.
What is a physical property?
The smallest unit of an element that retains its chemical identity.
What is an atom?
The molecular compound N₂O₅.
What is dinitrogen pentoxide?
Zn + 2HCl → ZnCl₂ + H₂
What is a single-displacement reaction?
If 5.0 mol of A reacts with 3.0 mol of B in a 1:1 reaction, this reactant limits product formation.
What is reactant B?
The ability of iron to rust in moist air is an example of this.
What is a chemical property?
A substance with a fixed composition that cannot be separated by physical means.
What is a pure substance?
The name of Fe₂O₃, assuming iron is in its most common oxidation state here.
What is iron(III) oxide?
A reaction type where ions exchange partners, often forming a precipitate.
What is a double-displacement reaction?
The reactant left over after the reaction is complete is known as this.
What is the excess reagent?
Density, melting point, and conductivity all fall under this category.
What are physical properties?
The law stating that mass is conserved during a chemical reaction.
What is the Law of Conservation of Mass?
CH₄ + 2O₂ → CO₂ + 2H₂O
What is a combustion reaction?
The correct way to identify the limiting reagent when given masses of reactants.
What is converting each reactant to moles of product formed and comparing?
The burning of gasoline is classified as this type of change.
What is a chemical change?
A homogeneous mixture with uniform composition throughout.
What is a solution?
The correct name for CuCl, not assuming copper’s charge without calculation.
What is copper(I) chloride?
A reaction that involves both oxidation and reduction occurring simultaneously.
What is a redox reaction?
In the reaction 2Al + 3Cl₂ → 2AlCl₃, fewer moles of this reactant would limit the reaction.
What is chlorine gas (Cl₂)?
A change that alters a substance’s appearance but not its chemical composition.
What is a physical change?
The numerical value equal to the weighted average of all naturally occurring isotopes of an element.
What is atomic mass?
