Answer:
a. 0.0022 M/s
b. 0.0011 M/s
Explanation:
Let's consider the following reaction.
2 NO(g) + O₂(g) → 2 NO₂(g)
The rate of disappearance of NO is 0.0022 mol NO. L⁻¹.s⁻¹
<em>a. At what rate is NO₂ being formed?</em>
The molar ratio of NO to NO₂ is 2:2. The rate of formation of NO₂ is:
<em>b. At what rate is molecular oxygen reacting?</em>
The molar ratio of NO to O₂ is 2:1. The rate of disappearance of O₂ is:

First, count the number of atoms of each element in a single molecule of Mg(ClO4)2.
Mg = 1 atom
Cl = 1 * 2 = 2 atoms
O = 4 * 2 = 8 atoms
Now multiply the number of atoms of each element per molecule of the compound by the number of moles of the compound. So
Mg = 1 * 4.50 = 4.50
Cl = 2 * 4.50 = 9.00
O = 8 * 4.50 = 36.00
So the answer is
4.50, 9.00, 36.00</span>
I don't know much about this, but probably the reason why your teacher circled 300k is because of what's in the photo below. If you couldn't tell from the photo, its because 300k isn't negative. Anyway this is my guess, based on my limited knowledge.
