Reactions Flashcard

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

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

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

How do you identify the products of a combustion reaction?

Back

In a combustion reaction, the products are typically carbon dioxide (CO2) and water (H2O) when hydrocarbons react with oxygen.

Front

What is the balanced equation for the combustion of ethylene (C2H4)?

Back

C2H4 + 3O2 → 2CO2 + 2H2O.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the Law of Conservation of Mass is upheld, showing that the number of atoms for each element is the same on both sides.

Front

What is the role of coefficients in a chemical equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction and are used to balance the equation.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction.
