Answer:
Double Bonds
Explanation:
CO2 has two double bonds going from carbon to the oxygen atoms. Each oxygen atom needs to bond twice and the carbon atom needs to bond four times. Carbon has four valence electrons, and oxygen has six. Carbon shares two of its valence electrons with each of the two oxygen atoms, forming two double bonds.
A, B, and C because they all equal 5.6 cm and it’s not close to 6.
Answer:
Zinc is Zn and Magnesium is Mg
Answer:
4.3 × 10⁻⁵ M s⁻¹
Explanation:
Step 1: Given data
- Rate constant (k): 2.20 × 10⁷ M⁻¹s⁻¹
- Concentration of NO ([NO]): 3.3 × 10⁻⁶ M
- Concentration of O₃ ([O₃]): 5.9 × 10⁻⁷ M
- First order with respect to both NO and O₃
Step 2: Write the balanced reaction
NO + O₃ ⇒ NO₂ + O₂
Step 3: Calculate the reaction rate
The rate law is:
rate = k × [NO] × [O₃]
rate = 2.20 × 10⁷ M⁻¹s⁻¹ × 3.3 × 10⁻⁶ M × 5.9 × 10⁻⁷ M
rate = 4.3 × 10⁻⁵ M s⁻¹
