What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. It typically forms between metals and nonmetals.

Front

What is the formula for the ionic compound formed between potassium (K) and fluorine (F)?

Back

KF

Front

How is power defined in physics?

Back

Power is the rate at which work is done or energy is transferred over time. It is calculated as Power = Work / Time.

Front

What is the formula to calculate work done?

Back

Work = Force x Distance.

Front

If a force of 35 Newtons is used to push a box a distance of 10 meters in 5 seconds, how much work is done?

Back

Work = 35 N x 10 m = 350 J.

Front

How do you calculate power if you know the work done and the time taken?

Back

Power = Work / Time.

Front

What is the power used if 350 J of work is done in 5 seconds?

Back

Power = 350 J / 5 s = 70 W.

Front

What is the difference between power and work?

Back

Power takes into account the time it takes to complete a task, while work is the total energy transferred.

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, which determines its chemical properties.

Front

What is the abbreviated electron configuration for barium (Ba)?

Back

[Xe] 6s².
