Answer:
pH = 14 - pOH = 14 - 6.907 = 7.903
=> [H₃O⁺] = 10^-pH = 10^-7.903 = 1.25 x 10⁻⁸M
Explanation:
Answer:
Sodium Chloride is salt
Explanation:
Basically, its used to help absorb and transport nutrients, its also used to help blood pressure along with maintaining the right balance of fluid. These will all be helpful to our bodies and environment.
It would be a gas. so gas is the answer
Answer:
[H3O+] = 1.0*10^-12 M
[OH-] = 0.01 M
Explanation:
We can use the following equation to find the hydronium ion concentration. Plug in the pH and solve for H3O+.
pH = -log[H3O+]
<u>[H3O+] = 1.0*10^-12 M</u>
Now, to find the hydroxide ion concentration we will use the two following equations.
14 = pH + pOH
pOH = -log[OH-]
14 = 12 + pOH
pOH = 2
2 = -log[OH-]
<u>[OH-] = 0.01 M</u>
In
this case, we can simply use a ruler to measure the heights of the signal. Use the
same ruler all throughout to reduce deviations in the measurement.
So
for example we have 3 isotopes, so we get 3 signals with heights of (for
example):
isotope
1 = 62
isotope
2 = 2
isotope
3 = 8
Therefore
the mass of the signals would be:
62
+ 2 + 8 = 72
The
fractional abundance of each isotope would be:
frac
isotope 1 = 62/72 = 0.86
frac
isotope 2 = 2/72 = 0.03
<span>frac
isotope 3 = 8/72 = 0.11</span>
