The first to do is to isolate the constant, k, to one side. The rate expression would then be:
k = rate/ <span>[A][B]^2
This constant, k, will be the same for the given reaction at a certain temperature. Then, we can relate a second rate to this reaction.
</span>rate1/ [A1][B1]^2 = rate2/ [A2][B2]^2
First question:
0.0810 / [A1][B1]^2 = rate2/ <span>[A2/2][3B2]^2
rate2 = (</span>0.0810 [A2/2][3B2]^2 )/ [A1][B1]^2
rate2 = 0.3645 M/s
Second Equation:
0.0810 / [A1][B1]^2 = rate2/ <span>[A2/2][3B2]^2
rate2 = (</span>0.0810 [3A2][B2/2]^2 )/ [A1][B1]^2
<span>rate2 = 0.0608 M/s</span>

Bismuth(III) Sulfide is a brownish powder that is soluble in acids.
In order to determine if the ion is positively charged or negatively charged
Hello!
To find the mass in grams of 100 atoms of carbon, we need to use Avogadro's number, which is 6.02 x 10^23 grams, and divide that by the total number of atoms.
Next, we would need to find how much one mole of carbon weighs. In this case, it is exactly 12 grams.
1. Divide by Avogadro's number
100 / (6.02 x 10^23) ≈ 1.66 x 10^-22
2. Multiply by one mole of carbon
(1.66 x 10^-22) x 12 ≈ 2.0 x 10^-21
Therefore, the mass of 100 atoms of carbon is equal to about 2.0 x 10^-21 grams.
