What are four types of chimical reactions?

Answer 1

Sublimation is the process where a solid turns directly into gas, bypassing the liquid state. Ice made of H2O (water) goes through a 3-phase, 2-step rocess involving melting (turning from solid to liquid) and evaporating (turning from liquid to gas). Dry ice (solid CO2) skips the melting step; it goes directly from solid to gas. Oxidation,in its original sense, refers to the combination of oxygen with another substance to produce a compound called an oxide. Iron, in the presence of water, combines with atmospheric oxygen to form a hydrated iron oxide, commonly called rust.

Answer 2

They include: Combustion, Synthesis, Decomposition and Single displacement. Others include: Double displacement and Acid base. Chemical reactions are processes in which substances change into other substances.

Answer 3

The main four types of Chemical reactions are:

1) Combination or synthesis

2) Decomposition

3) Substitution or Single Replacement

4) Metathesis or Double Displacement

Answer 4

There are four common types of chemical reactions.

1. Synthesis Reactions

A+B->AB

This kind of reactions build or synthesize things. An example would be building protons from amino acids.

2. Decomposition Reactions

AB->A+B

These are mostly catabolic reactions. An example would be digesting food.

3. Exchange Reactions

AB + CD -> AD + CB

These exchange parts and make a new chemical compound.

4. Reversible Reaction

A+B <-> AB

Chemical compounds can be both made and broken down.

ADD: synthesis, decomposition, single replacement, and double replacement

Answer 5

There are six types of chemical reactions: synthesis, decomposition, single displacement, double displacement, acid-base, and combustion.
