Answer:

3.15 × 10⁻⁶ mol H₂/L.s

1.05 × 10⁻⁶ mol N₂/L.s

Explanation:

Step 1: Write the balanced equation

2 NH₃ ⇒ 3 H₂ + N₂

Step 2: Calculate the rate of production of H₂

The molar ratio of NH₃ to H₂ is 2:3. Given the rate of decomposition of NH₃ is 2.10 × 10⁻⁶ mol/L.s, the rate of production of H₂ is:

2.10 × 10⁻⁶ mol NH₃/L.s × 3 mol H₂/2 mol NH₃ = 3.15 × 10⁻⁶ mol H₂/L.s

Step 3: Calculate the rate of production of N₂

The molar ratio of NH₃ to N₂ is 2:1. Given the rate of decomposition of NH₃ is 2.10 × 10⁻⁶ mol/L.s, the rate of production of N₂ is:

2.10 × 10⁻⁶ mol NH₃/L.s × 1 mol N₂/2 mol NH₃ = 1.05 × 10⁻⁶ mol N₂/L.s

<h3>What is pollution?</h3>

The term pollution has to do with the introduction of materials and energy that are harmful to the environment and also the fauna and flora.

1) The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.

2) If the government committee learns about the side effects and decides the medication is not safe for public use, then the committee used an anecdote and did not use science to make the decision.

3) The type of research that might result in a law that restricts hunting of a particular species is research showing the species is endangered in other geographical areas

How many valence electrons do the halogens possess?
BabaBlast [244]

Answer:

<em></em>

<em></em>

  • <em>The halogens posses </em><u><em>seven </em></u><em>valence electrons</em>

Explanation:

  • <em>Valence electrons </em>are the electrons in the outermost orbitals of the atoms, which are the orbitals with the highest main energy level (principal quantum number).

  • Halogens are the elements of the group 17 of the periodic table: F, Cl, Br, I, At.

  • You can tell the number of valence electrons of the representative elements from the number of the group to which they belong. For the representative elements, the number of valence electrons equal the unit digit of the group number.

        This table summarizes it:

Group number        number of valence electrons

     1                                      1

     2                                     2

    13                                     3

    14                                     4

    15                                     5

    16                                     6

    17                                      7

    18                                      8

  • So, in conclusion, <em>the halogens possess 7 valence electrons.</em>
