Question: What Are Simple Reactions?

How do you classify reactions?

Classifying Chemical ReactionsSynthesis reactions.

Two or more reactants combine to make 1 new product.

Decomposition reactions.

A single reactant breaks down to form 2 or more products.

Single-replacement reactions.

A single element replaces a similar element of an adjacent reactant compound.

Double-replacement reactions.

Combustion reactions..

Which is the most dangerous chemical reaction?

One of the most dangerous chemical reactions is a mixture of cesium with water, because when these two substances come into contact, there is an immediate explosion. This reaction is so dangerous that even if a very little amount of this metal is added to a glass of water, the glass will explode in fragments.

What is an example of a reaction?

A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

What are the 3 most important chemical reactions?

Combustion of methane (hydrocarbons)Photosynthesis.Synthesis of sulfuric acid.Equilibrium of carbonic acid and carbon dioxide gas.Biological formation of calcium carbonate.Rusting of iron.Production of hydrogen from the action of acid on metal.Oxidation of alcohol.More items…

What are three examples of physical changes?

Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

What are 10 examples of physical changes?

Examples of Physical ChangesCrushing a can.Melting an ice cube.Boiling water.Mixing sand and water.Breaking a glass.Dissolving sugar and water.Shredding paper.Chopping wood.More items…•

What are 4 examples of physical changes?

Examples of Physical Changes You See Every DayAn ice cube melting into water in your drink.Freezing water to make ice cubes.Boiling water evaporating.Hot shower water turning to steam.Steam from the shower condensing on a mirror.

Which are the most common chemical reactions in the body?

In human body the most common or you can say usual chemical reaction is respiration. Respiration is simply gaseous exchange, with release of energy. It can be stated as in oxidation reaction, where which oxygen from air get absorbed and mixed with food and then it produces energy.

Is cooking an egg a chemical reaction?

Cooking the egg is an example of a chemical change.

What are 3 examples of a chemical reaction?

Common Chemical ChangesThe rusting of iron.Combustion (burning) of wood.The metabolism of food in the body.Mixing an acid and a base, such as hydrochloric acid (HCl) and sodium hydroxide (NaOH)Cooking an egg.Digesting sugar with the amylase in saliva.Mixing baking soda and vinegar to produce carbon dioxide gas.More items…•

What are the 5 basic chemical reactions?

In this chapter, we will discuss five major categories of chemical reactions: (1) Combination (or Synthesis) Reactions, (2) Decomposition Reactions, (3) Single Replacement Reactions, (4) Double Replacement Reactions, and (5) Redox Reactions.

What are the 4 types of reactions?

Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.

What is an example of physical reaction?

Physical reactions occur when molecules rearrange to produce a physical change. … Common examples of physical reactions include using water to make ice and dissolving sugar cubes in water to make sugar water.
