<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>
Answer:
It says in the question its up to you to decide, so you have to graph the weather changes then explain why you graphed it in that way.
Answer:
OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)
Explanation:
The net ionic equation is a way yo write a chemical equation that list only the species that are involved in the reaction.
For the reaction:
NaOH(aq) + NH₄Br(aq) → NaBr(aq) + NH₃(g) + H₂O(l)
Ionic equation is:
Na⁺(aq) + OH⁻(aq) + NH₄⁺(aq) + Br⁻(aq) → Na⁺(aq) + Br⁻(aq) + NH₃(g) + H₂O(l)
<em>-Ions comes from the species that are in aqueous phase-</em>
And net ionic equation is:
<em>OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)</em>

Answer:
Germanium.
Explanation:
In a neutral atom: the number of protons = the number of electrons.
Atomic number of a neutral atom = number of electrons = number of protons.
- Phosphorous is an element with atomic number 15 and thus contains 15 electrons and 15 protons.
- Cobalt is an element with atomic number 27 and thus contains 27 electrons and 27 protons.
- <em>Germanium is an element with atomic number 32 and thus contains 32 electrons and 32 protons.</em>
<em></em>
- Sulfur is an element with atomic number 16 and thus contains 16 electrons and 16 protons.
