- Temperature change happened.
- State of reaction changed.
- Production of Light.
- Volume Change.
- Change in Smell or Taste.
What are the 5 basic types of chemical reactions?
This becomes much easier for students to do when they learn the pattern of 5 basic categories of chemical reactions: synthesis, decomposition, single replacement, double replacement, and combustion.
What are three characteristics of chemical reactions?
The general characteristics of chemical reactions are:
- Evolution of a gas.
- Formation of a precipitate.
- Change in temperature.
- Change in state.
What are the 5 characteristics of a chemical change?
Some of the characteristics of chemical change are:
- A new substance is formed.
- Changes occur in the composition of the substance.
- It is normally irreversible.
- It might give off light or heat.
- A colour change might occur.
- It is a permanent change.
- Molecules change.
What are the 4 factors that affect the rate of chemical reaction?
The rate of a chemical reaction is influenced by many different factors, including reactant concentration, surface area, temperature, and catalysts.
How do you classify chemical reactions?
Most chemical reactions can be classified into one or more of five basic types: acid–base reactions, exchange reactions, condensation reactions (and the reverse, cleavage reactions), and oxidation–reduction reactions.
What is the other name of chemical reaction?
Answer and Explanation: There are multiple synonyms for the term chemical reaction. These include oxidization and/or reduction, as well as combustion (e.g. the burning of fuel) and decomposition.
What are the 4 chemical properties?
Key Takeaways: Chemical Property
Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion.
What are the characteristics of chemical formula?
Types of Chemical Formulas
| Molecular | Empirical | Structural |
|---|---|---|
| Shows the number of atoms for each element in the compound | Shows the simplest ratio of atoms of the elements in the compound | Shows the number of atoms for each element in the compound as well as the arrangement and bonds of the atoms |

What are characteristics of chemical equilibrium?
The main characteristics of chemical equilibrium are as follows: At chemical equilibrium, the rate of forward and reverse reactions are equal. All the reactants and products are present at equilibrium. The position of equilibrium is not affected by a catalyst.
What are the characteristics of physical and chemical change?
In a physical change, no new substance is formed. A chemical change is always accompanied by one or more new substance(s). Physical change is easily reversible i.e original substance can be recovered. Chemical changes are irreversible i.e. original substance cannot be recovered.
What are the characteristics of different classes of chemical reactions?
The characteristics of a chemical reaction are :
- Evolution of gas.
- Formation of a precipitate.
- Change in color.
- Change in temperature.
- Change in state.
- Formation of new substances.
What are the characteristics of reactants and products?
Reactants are substances that start a chemical reaction. Products are substances that are produced in the reaction.
Which of the following is not a characteristic of a chemical reaction?
No net energy change is involved.
What are the types of chemical reaction explain with example?

| Types of Chemical Reactions | Explanation | General Reaction |
|---|---|---|
| Combination reaction | Two or more compounds combine to form one compound. | A + B → AB |
| Decomposition reaction | The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. | AB → A + B |
