Unit 3 Batteries Review

Front

What charge does an atom have after gaining an electron?

Back

Negative charge.

Front

What happens to the equilibrium when Cl2(g) is removed from the reaction H2(g) + Cl2(g) ⇌ 2HCl(g)?

Back

The equilibrium shifts left.

Front

If a pith ball with charge +q feels a force F at distance d from another +q charge, what is the force when the distance is increased to 2d?

Back

The force is 1/4 F.

Front

What are materials that allow electricity to move through them easily called?

Back

Conductors.

Front

What happens to the equilibrium of the reaction heat + N2 + O2 ↔ 2NO when heat is added?

Back

The equilibrium shifts right.

Front

What is the definition of a conductor?

Back

A material that allows electricity to flow through it easily.

Front

What is the effect of increasing the distance between two like charges on the force between them?

Back

The force decreases.

Front

What is the principle behind the equilibrium shift in chemical reactions?

Back

Le Chatelier's Principle states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.

Front

What is the charge of an atom that loses an electron?

Back

Positive charge.

Front

What is the relationship between force and distance in electrostatics?

Back

Force is inversely proportional to the square of the distance between charges.
