Multiple Choice

Which statement best describe the structure of a carbonate anion?

• A) The electron geometry of carbon in a carbonate anion is trigonal planar with a sp² hybridization and bond angles are 120°. There is a π-bond formed between a non-hybridized "C" p-orbital overlapping with an "O" p-orbital.
• B) The electron geometry of carbon in a carbonate anion is trigonal planar with a sp² hybridization and bond angles are <120°. There is a π-bond formed between a non-hybridized "C" p-orbital overlapping with an "O" p-orbital.
• C) The electron geometry of carbon in a carbonate anion is trigonal planar with a sp² hybridization and bond angles are <120°. There is a π-bond formed between a hybridized "C" p-orbital overlapping with an "O" p-orbital.

Structural Encoding

Structural encoding is the process of encoding information according to the structure of objects, focusing on the physical features rather than the meaning.

Phonemic Encoding

The process by which sounds are translated into mental symbols for storage in memory.

Semantic Encoding

The process of encoding sensory information into memory, attaching meaning and significance to it.

Phonemic Encoding

Phonemic encoding is the process of breaking down and translating spoken words into their basic sound units or phonemes, facilitating language understanding and processing.
