One molecule of water contains two atoms of hydrogen and one atom of oxygen, the atomicity of water is three.
Answer:
b All of them are highly reactive nonmetals
Answer:
a. 4900 mL; b. 4900 cm³ c. 4.9x10⁻³ m³
Explanation:
1 L = 1 dm³
4.9 L = 4.9 dm³
1 dm³ = 1000 cm³ → 4900 cm³
1 cm³ = 1 mL (4900 mL)
1 dm³ = 1x10⁻³ m³ → 4.9x10⁻³ m³
Answer/Explanation:
Things that will vary include the distribution of electrons between atoms, lone pairs, and bonds, the number of single vs double or triple bonds, and the formal charges on atoms in the structure.
All resonance forms of the same molecule or ion must have the same number of atoms, connected in the same way, and the same number of total electrons.
