AP Chemistry Thou Shall Not Forget- Part 1

Front

What happens to the 1st ionization energy when an electron is in a lower energy level?

Back

It has a higher 1st ionization energy.

Front

What is the hybrid orbital used in carbon dioxide (CO2)?

Back

sp hybridization.

Front

What type of hybridization does a carbon atom undergo in ethylene (C2H4)?

Front

What property does filtering separate mixtures based on?

Back

Particle size.

Front

Define ionization energy.

Back

The energy required to remove an electron from an atom or ion.

Front

What is hybridization in chemistry?

Back

The mixing of atomic orbitals to form new hybrid orbitals.

Front

Explain the difference between sp, sp2, and sp3 hybridization.

Back

sp: linear geometry, 180° bond angle; sp2: trigonal planar geometry, 120° bond angle; sp3: tetrahedral geometry, 109.5° bond angle.

Front

What is the significance of a burette in titration experiments?

Back

It allows for precise measurement and delivery of liquid reagents.

Front

How does particle size affect the process of filtration?

Back

Smaller particles pass through the filter, while larger particles are retained.
