Chemical Reactions

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

What type of reaction occurs when quicklime (CaO) reacts with water to form slaked lime (Ca(OH)2)?

Back

This is a combination reaction, where two or more substances combine to form a single product.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which reactants are transformed into products, and the law of conservation of mass applies.

Front

What type of reaction is represented by the equation Fe + NaBr -> FeBr3 + Na?

Back

This is a single replacement reaction, where one element replaces another in a compound.

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that in a chemical reaction, the mass of the reactants is equal to the mass of the products.

Front

What is a combination reaction?

Back

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

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 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 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 is the role of energy in chemical reactions?

Back

Energy is involved in chemical reactions as it can be absorbed or released, affecting the reaction's temperature and rate.
