<span>The reason why it is easiest to assume the first step is slow is because that would be your rate determining step and would give you the rate law given in the problem. So you take the two compounds from the rate law given and put them as your two reactants in your first step:
NO2 + F2 ---> NO2F + F (all gases)
Your next step needs to make sense for your overall reaction. And you also need to have an intermediate which in this case will be F:
F + NO2 ---> NO2F (again all gases) This is the fast step.
Your intermediate cancels out to give you your overall equation:
2NO2 + F2 ---> 2NO2F (all gases)</span>
Oxygen is the correct answer hope this helps
Answer:
CO2
Explanation:
(I Just took the test)
At STP 1 mol=22.4 Liters, so we now know that it is asking for which of the gasses has a molar mass of 44, and CO2 is th only one with that molar mass
Answer:
p orbitals only
Explanation:
Carbon has an atomic number of 6 so its electron configuration will be 1s² 2s² 2p². It has two orbitals as indicated with the 2 as its period number with the outer orbital have 4 valence electrons. So carbon is in the p-orbital, period 2 and in group 4.
Answer:
The grating spacing is 
Explanation:
From the question we are told that
The wavelength is 
The angle is 
The order of the spectrum is 
Generally in grating grating the condition for maxima to occur is

where d is the grating spacing
making d the subject of the formula

Substituting values
