To calculate the hydronium ion concentration for a solution that has a pH of 10.61, you would do the following. Since pH=-log[H3O+]. Input the pH value and solve for [H3O+].
10.61=-log[H3O+]
-10.61=log[H3O+]
-10.61=log10[H3O+]
[H3O+]=10^-10.61
[H3O+]= 2.4547x10^-8.
Answer:
92.6%
Explanation:
Hello there!
In this case, according to the first-order kinetics, we can write:
Whereas we need to know the rate constant in order to compute the percentages, given the half-life:
In such a way, we can now compute the fraction in which the reaction has been completed after 3 hrs:
And the percent would be 92.6% after multiplying the fraction by 100 %.
Best regards!
Answer:
It would take sound <em><u>104.998 seconds</u></em> to travel across lake tahoe.
Explanation:
First let's convert the miles to meters, so, 21.6 miles = 34754.4 meters
Now, we will divide this number in meters by 331. So, 34754.4 / 331 = 104.998
And what will the unit be? Seconds will be the unit for time here so 104.998 seconds.
Answer:
20 atoms
broo this is easy plz give me harder questions smh
