Balancing and Types of Reactions!

Front

What does the law of conservation of mass state?

Back

Matter can neither be created nor destroyed.

Front

How do you determine the number of atoms of an element in a chemical equation?

Back

Count the coefficients and subscripts for that element on both sides of the equation.

Front

What is a coefficient in a chemical equation?

Back

A number placed in front of a formula to indicate how many molecules or moles of that substance are present.

Front

What are reactants in a chemical reaction?

Back

Substances that undergo change during a chemical reaction, typically found on the left side of the equation.

Front

What type of reaction is represented by the equation Mg3(PO4)2 + H2 --> Mg + H3PO4?

Back

Single Replacement Reaction.

Front

What is a product in a chemical reaction?

Back

Substances that are formed as a result of a chemical reaction, typically found on the right side of the equation.

Front

What is the purpose of balancing a chemical equation?

Back

To ensure that the number of atoms for each element is the same on both sides of the equation, in accordance with the law of conservation of mass.

Front

What is a double replacement reaction?

Back

A type of reaction where two compounds exchange ions or bonds to form two new compounds.

Front

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

Back

A synthesis reaction combines two or more substances to form a new compound, while a decomposition reaction breaks down a compound into simpler substances.

Front

What is an example of a combustion reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat, such as burning hydrocarbons.
