Compounds and Stoichiometry CH4

Question 1

Two or more reactants forming one product: A + B > C

Answer 1

Combination Reaction

Question 2

A single reactant breaks down into two or more products, usually as a result of heating, high-frequency radiation, or electrolysis: C > A + B

Answer 2

Decomposition Reaction

Question 3

A special type of reaction that involves fuel (usually a hydrocarbon) and an oxidant (normally oxygen). In its most common form, these reactants form the two products of carbon dioxide and water: CH4 + 2O2 > CO2 +H2O

Answer 3

Combustion Reaction

Question 4

When an atom or ion in a compound is replaced by an atom or ion of another element: Cu + AgNO3 > Ag +CuNO3

Answer 4

Single - Displacement Reaction (AKA Oxidation-Reduction Reaction)

Question 5

Elements from two different compounds swap with each other to form two new compounds: CaCl2 + 2AgNO3 > Ca(NO3)2 + 2AgCl

Answer 5

Double - Displacement Reaction (AKA Metathesis Reaction)

Question 6

A specific type of double displacement in which an acid reacts with a base to produce a salt (and usually water): HCl + NaOH > NaCl + H2O

Answer 6

Neutralization Reaction

Question 7

Ferrous Ion

Answer 7

Fe2+

Question 8

Ferric Ion

Answer 8

Fe3+

Question 9

Cuprous Ion

Answer 9

Cu+

Question 10

Curpic Ion

Answer 10

Cu2+

Question 11

What are some examples of monoatomic anions that are named by dropping the ending of the element name with the added “ide”?

Answer 11

H- : Hydride

F- : Fluoride

O2- : Oxide

S2-: Sulfide

N3-: Nitride

P3-: Phosphide

Question 12

Many polyatomic anions contain oxygen and are therefore called oxyanions. When an element forms two oxyanions, the name of the one with less oxygen ends in “-ite” and the one with more oxygen ends in “-ate”. What are some examples?

Answer 12

Question 13

Solutes that enable solutions to carry currents are called? The electrical conductivity of aqueous solutions is governed by the presence and concentration of ions in the solution.

Answer 13

Electrolytes
