b
![r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B%20k%20%5BNO_2%5D%5E2%20%5BF_2%5D%7D%7B%5BNO_2F%5D%7D)
Explanation:
From the question we are told that
The formation mechanism is
The overall balanced equation is
We combined the first reactant and the last product and the balanced the number of mole
The observable rate law is
This rate law is derived from the balanced chemical equation
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
The valence of lead is 4.
Hence the name of the compound is called Lead (IV) oxide.
<h3>Further explanation</h3>
Given
PbO₂ compound
Required
The valence of Pb
Solution
The oxidation number of element O in the compound = -2, except for OF₂ the oxidation state = + 2 and the peroxides (Na₂O₂, BaO₂) the oxidation state = -1 and superoxide, for example KO₂ = -1/2.
The oxidation state in the uncharged compound = 0,
So The oxidation state of Pb :
Pb + 2.(-2) = 0
Pb - 4 = 0
Pb = +4
Your independent variable is - The kind of nail polish used
Your dependent variable is - How much the nails have grown
And your constant is - Amount of time allowed for growth
