Chapter 4 Flashcards

1
Q

Molecular & Empirical Formula

A

Similarities: Contain same elements in same ratios

Differences: Molecular formula give actual number of atoms of each element in compound. Empirical formulas give ratio and may or may not give actual number of atoms

Q

Double-Displacement (Metathesis)

A

Occur when elements from two different compounds trade places with each other to form two new compounds
* NaNO3 + CuOH = NaOH + CuNO3

A

Occurs when an ion of one compound is replaced with another element
* Zn + AgCl = ZnCl + Ag

Q

Electrolytes

A

Contain equivalents of ions fom molecules that dissociate in solution
* Strength depends on its degree of dissociation/solvation
* Ex: HCl, MgBr2

Q

Ionic Compounds

A

Made of atoms held together by ionic bonds
* Ionic bonds associate charged particles with lage differences in electonegativity
* Large arrays of ions in crystalline solids
* Electrons not shared byt donated from less electronegative atom to more electronegative atom

17
Q

Oxidation-Reduction Reaction

A

Transfer of electons
Changes from + oxidation state to neutral and other changes from netural to + oxidation state

18
Q

Combustion Reaction

A

Occurs when fuel and oxidant (usually O) react forming products of water and carbon dioxide (if fuel is hydrocarbon)
