Answer:
A. 444.5 pm
Explanation:
We know that:
i.e.
in a face-centered cubic crystal, the number of atoms per unit cell is (n) = 4
The molar mass of manganese (II) oxide
Density is given as 5.365 g/cm³
Avogadro constant = 6.023 × 10²³ atoms/mol
∴
Making th edge length "a" the subject, we get:
a = 4.445 × 10⁻⁸ cm
a = 444.5 pm
Answer:
Explanation:
Hello!
In this case, since the reaction may be assumed in chemical equilibrium, we can write up the rate law as shown below:
However, since the rate of reaction at equilibrium is zero, due to the fact that the concentrations remains the same, we can write:
Which can be also written as:
Then, we solve for the concentration of NO to obtain:
