Argon is a suitable choice for light bulbs because it's inert. Compared to a reactive gas like oxygen, the metal filimant would burn up in a reactive enviroment, which is why a noble gas is used.
<span><span>N2</span><span>O3</span><span>(g)</span>→NO<span>(g)</span>+<span>NO2</span><span>(g)</span></span>
<span><span>[<span>N2</span><span>O3</span>]</span> Initial Rate</span>

<span>0.2 M r<span>(t)</span>=1.32</span> M/s

We can have the relationship:

However,

Also, we assume m=1 which is the order of the reaction.
Thus, the relationship is simplified to,
r(t)/r0(t) = 2
r<span>(t)</span>=k<span>[<span>N2</span><span>O3</span>]</span>
0.66 <span>M/s=k×0.1 M</span>

Answer/Explanation:
In June 1998 in Japan a scientist discovered that neutrinos (which is a type of particle) has weight, mass. This was later proven with some very convincing strong evidence.

I might be wrong, but please tell me.
Answer:
Explanation:
Hello,
In this case, for the given reaction:
We find a 1:2 molar ratio between the acid and the base respectively, for that reason, at the equivalence point we find:
That in terms of concentrations and volumes we can compute the concentration of the acid solution:
Best regards.
