Chemistry Chapter 6 Test

Front 1

Singe Replacement Reaction

Back 1

is a reaction in which one element takes the place of another element in a compound.

In a single-replacement reaction, both the reactants and the products are an element and a compound.

Front 2

Net ionic equation

Back 2

Net ionic equations show only those particles directly involved in the reaction and is balanced with respect to mass and charge.

Front 3

Coefficient

Back 3

a small whole number that appears in front of a formula in a balanced chemical equation

Front 4

Spectator ion

Back 4

are ions that stay in solution.
(are the ions that do not form precipitants)

Front 5

Catalyst

Back 5

is a substance that speeds up the reaction but is not used up in the reaction
A catalyst is neither a reactant nor a product, so its formula is written above the arrow in a chemical equation.

Front 6

Reactants

Back 6

are substances that undergo a chemical change

Front 7

Products

Back 7

new substances formed from a chemical change

Front 8

Synthesis or Combination Reaction
+ after the reaction there is always...

Back 8

is a reaction in which two or more substances combine to form a single product
-there is always a single product.

Front 9

Double replacement reaction

Back 9

a chemical change that involves an exchange of positive ions between two compounds
-cations replace cations and the solid/precipitant can tell you which elements/ions will be spectator ions w/the rules of solubility

Front 10

Combustion

Back 10

a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat and light

Front 11

decomposition

Back 11

a chemical change in which a single compound is broken down into two or more simpler products

Front 12

The complete combustion of a hydrocarbon produces...

Back 12

carbon dioxide and water.

Front 13

A skeleton equation

Back 13

is a chemical equation that does not indicate the relative amounts of reactants and products

Front 14

Balanced equation

Back 14

a chemical equation in which mass is conserved; each side of the equation has the same number of atoms of each element

Front 15

Pt
-->

Back 15

A formula written above or below the yields sign indicates its use as a catalyst

Front 16

Δ
-->
or
heat
-->

Back 16

Indicates that heat is supplied to the reaction

Front 17

What determines whether metal will replace another metal from a compound in a single- replacement reaction?

Back 17

the levels of reactivity the metals hold determine whether a metal will replace another metal in a chemical reaction. A metal must be more reactive then the metal it is replacing/displacing otherwise that reaction can't take place.
