12, if the decimal is over five, round up. If it's not, round down. Not sure what you mean by significant figures.

In the first 15.0 s of the reaction, 1.7×10−2 mol of O2 is produced in a reaction vessel with a volume of 0.440 L . What is the

Step2247 [10]

Answer:

$Rate=2.57x10^{-3}\frac{M}{s}$

Explanation:

Hello,

In this case, for the reaction:

$2N_2O(g) \rightarrow 2N_2(g)+O_2(g)$

We can easily compute the average rate by firstly computing the final concentration of oxygen:

$[O_2]=\frac{0.017mol}{0.440L}=0.0386M$

Then, we compute it by using the given interval of time: from 0 seconds to 15.0 seconds and concentration: from 0 M to 0.0386M as oxygen is being formed:

$Rate=\frac{0.0386M-0M}{15.0s-0s}\\ \\Rate=2.57x10^{-3}\frac{M}{s}$

Regards.

What is the pH of a solution with [H+] = 2.3 x 10-6

WITCHER [35]

Answer:

5.64

Explanation:

We are given;

The concentration of H+ ions as 2.3 x 10^-6 M

We are required to get the pH

pH is given by getting the negative logarithm of hydrogen ion concentration.
That is; pH = -log [H+]

Therefore;

pH = - log [2.3 x 10^-6 M]

= 5.638

= 5.64

Hence the pH of the solution is 5.64
