Types of Chemical Reactions

atoms are rearranged to form products

• Physical change
• Nuclear reaction
• Phase transition
• Chemical reaction

2 elements or molecules combine to form 1 molecule

• Double displacement reaction
• Single displacement reaction
• Decomposition reaction
• Combination reaction
• Combustion reaction

Answer explanation

Combination is same as synthesis

1 molecule is broken down into 2 separate elements or molecules

• Double displacement reaction
• Single displacement reaction
• Decomposition reaction
• Combination reaction
• Combustion reaction

One element or molecule replaces another element in a molecule

• Double displacement reaction
• Single displacement reaction
• Decomposition reaction
• Combination reaction
• Combustion reaction

Elements in molecules replace each other

• Double displacement reaction
• Single displacement reaction
• Decomposition reaction
• Combination reaction
• Combustion reaction

A reaction of a compound containing carbon and hydrogen with oxygen gas; releases carbon dioxide gas and water vapor.

• Double displacement reaction
• Single displacement reaction
• Decomposition reaction
• Combination reaction
• Combustion reaction

Carbon is an element that takes the solid form of either graphite or diamond. Carbon is one of the basic elements of any living thing. Carbon is known as the most essential element for life, and it's the second most abundant — after oxygen — in the human body.

• Carbon is a gas at room temperature.
• Carbon is essential for life and is the second most abundant element in the human body.
• Carbon is not found in living organisms.
• Carbon is the most abundant element in the human body.

A transfer of electrons that changes the Oxidation number(charge) of the atom from the reactant to the product side.

• covalent bond
• ionization energy
• Oxidation/Reduction (Redox)

• electron affinity

​ (a)   reactions are important because they ​ (b)   energy through reactions such as ​ (c)   in a car engine and ​ (d)   in living organisms. They have 2 parts: reduction, which is ​ (e)   electrons, and oxidation, which is losing electrons.

• Redox
• release
• combustion
• cellular respiration
• gaining

What reaction has the following general formula:

A + CD --> C + AD

• Combination

• Decomposition

• Single Replacement

• Double Replacement

• Combustion
