Chemical Reactions & Forces

Front

What is a chemical reaction?

Back

A process in which substances (reactants) undergo a transformation to form new substances (products).

Front

What is a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides, indicating that mass is conserved.

Front

What type of reaction is represented by the equation: @@2H_2 + O_2 ightarrow 2H_2O@@?

Back

Synthesis reaction, where two or more reactants combine to form a single product.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it remains constant.

Front

What is a decomposition reaction?

Back

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

Front

What is frictional force?

Back

A force that opposes the relative motion between two surfaces in contact.

Front

What does Newton's first law of motion state?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another in a compound.

Front

What is a double displacement reaction?

Back

A reaction where two compounds exchange ions or elements to form two new compounds.

Front

What is the difference between an endothermic and exothermic reaction?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.
