Answer:

the equation is well balanced .

Explanation:

for an equation to the balance it must have the same number of atoms of all the element in both the reactants and product.

from the equation above

we have 1 calcium on the left and 1 calcium on the right.

we have 1 Carbon on the left and 1 Carbon on the right.

we have 3 Oxygen on the left and 3 oxygen on the right.

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.

nikklg [1K]

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
