Chemical Reactions & Forces

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more substances combine to form a new compound, represented as A + B → AB.

Front

What happens to gravitational force when the distance between two objects is increased?

Back

The gravitational force decreases; specifically, if the distance is doubled, the force is reduced to a quarter of its original value.

Front

What is frictional force?

Back

Frictional force is a force that opposes the relative motion between two surfaces in contact.

Front

What determines the strength of gravitational force between two objects?

Back

The strength of gravitational force is determined by the masses of the objects and the distance between them, according to Newton's law of universal gravitation.

Front

What is the formula for gravitational force?

Back

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 substances, represented as AB → A + B.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another in a compound, represented as A + BC → AC + B.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, represented as AB + CD → AD + CB.

Front

What is Newton's first law of motion?

Back

Newton's first law states that 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 a net external force.
