Chemistry Unit 6 Balancing

Front

What type of reaction is represented by the equation C₃H₆O + 4O₂ → 3CO₂ + 3H₂O?

Back

Combustion

Front

What does (aq) indicate about a substance in a chemical equation?

Back

It means the substance is dissolved in water.

Front

What type of reaction occurs when one element replaces another in a compound due to reactivity?

Back

Single replacement reaction.

Front

What is the definition of a synthesis reaction?

Back

Reactants combine to produce one product.

Front

What type of reaction is represented by the equation Pb(NO₃)₂ + KI → KNO₃ + PbI₂?

Back

Double replacement.

Front

What is the general form of a combustion reaction?

Back

A hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

In a single replacement reaction, what determines if one element can replace another?

Back

The reactivity of the elements involved.

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction combines reactants to form one product, while a decomposition reaction breaks down a compound into simpler products.

Front

What is the significance of balancing chemical equations?

Back

It ensures the law of conservation of mass is upheld, meaning the number of atoms of each element is the same on both sides of the equation.

Front

What is an example of a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.
