Answer:
FC of C = -1
General Formulas and Concepts:
- Lewis Dot Structures
- Resonance Structures
- Formal Charge: FC = # of valence e⁻ - # of lone e⁻ - # of bonds
Explanation:
<u>Step 1: Define</u>
Carbon (C)
- 4 valence e⁻
- 2 lone e⁻
- 3 bonds
Oxygen (O)
- 6 valence e⁻
- 2 lone e⁻
- 3 bonds
<u>Step 2: FC of C</u>
- Substitute: FC = 4e⁻ - 2e⁻ - 3
- Subtract: FC = -1
According to the glossary in the back of 'Chemistry: A Central Science - Twelfth Edition', a precipitate is "An insoluble substance that forms in, and separates from, a solution."
The correct answer is letter B. Genetic engineering has shown a great leap in Science because we can now harness the ability of mutations of cells in crops and in other aspects. Flour is a commodity that is greatly needed by the masses and learning how to genetically modify its components to help it breed better is a great advantage for any society.
