Writing Equations and Types of Reactions

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. For example, 4Si + S8 → 2Si2S4.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. An example is C3H8 + O2 → H2O + CO2.

Front

What is a double displacement reaction?

Back

A double displacement reaction, also known as a double replacement reaction, is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is the formula for copper (II) hydroxide?

Back

The formula for copper (II) hydroxide is Cu(OH)2.

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. An example is MgCl2.

Front

What are the characteristics of a chemical equation?

Back

A chemical equation represents a chemical reaction, showing the reactants on the left and the products on the right, with coefficients indicating the number of molecules involved.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the mass of the reactants equals the mass of the products.

Front

What is the difference between a reactant and a product?

Back

A reactant is a substance that undergoes a chemical change in a reaction, while a product is a substance that is formed as a result of that reaction.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, ensuring the law of conservation of mass is upheld.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
