Synthesis and Decomposition Reactions Flashcards
What are the 5 types of reactions?
- synthesis
- decomposition
- single displacement
- double displacement
- combustion.
What ia a synthesis reactions also called?
a combination reactions
what is the genral equation for synthesis reactions?
A+ B → AB
What must the product always be in a synthesis. reaction?
a single compound
A metal element can combine with a non-metal element to form an…
ionic compound
Two non metal elements can combine to form a…
molecular compound
What reactants produce acids?
nonmetal oxides and water
What reactants produce bases?
metal oxides and water produce hydroxide
What is the decomposition reaction general formula?
AB→ A + B
Define a decomposition reaction
a reaction where a more complex molecule breaks down to form two or more simpler products
In a synthesis reaction, what do two elements form?
a binary compound
In a synthesis reaction, what do a metal oxide and carbon dioxide form?
the metal carbonate
In a synthesis reaction, what doe a metal chloride and oxygen form?
the metal chlorate
In a synthesis reaction, what do a metal oxide and water form?
a metal hydroxide
In a synthesis reaction, what do a non-metal oxide and water form?
the oxyacid
What is an acidic oxide?
an oxide that forms an acidic solution when dissolved in water
Describe the process from car to air for nitrogen oxides
- in car engines, the high temperature causes itrogen to undergo a synthesis reaction iwth oxygen
- nitrogen monoxde is released back into the atmosphere and undergoes further reaction iwth oxygen to form nitrogen dioxide
- nitrogen dioxide is toxic and combines with water droplets in air to form nitric acid and nitrous acid
Describe the process of sulfur oxides
- combustion of fossil fuels can produce sulfur dioxide
- once in atmosphere, sulfur dioxide reacts with additional oxygen to produce sulfur trioxide
- sulfur trioxide combines with water in the atmosphere to form sulfuric acid
- forms acid precipitation
What are basic oxides?
an oxide that forms a basic solution when dissolved in water - most metallic elements form basic oxides
What does a binary compound breakdown into in a decomposition reaction?
its elements
What do metal carbonates breakdown into in a decomposition reaction?
the metal oxide and carbon dioxide gas
what do chlorates breakdown into in a decomposition reaction?
the metal chloride and oxygen gas
what do metal hydroxides breakdown into in a decomposition reaction?
the metal oxide and water
what do oxyacid breakdown into in a decomposition reaction?
the non-metal oxide and water
what do metal nitrates breakdown into in a decomposition reaction?
the metal nitrite and oxygen gas
What does a metal oxide breakdown into in a decomposition reaction?
a metal and oxygen
What does a metal hydrate breakdown into in a decomposition reaction?
into an anhydrous compound and water
