Answer:
<h2>6.91 </h2>
Explanation:
To find the pH we must first find the pOH
The pOH can be found by using the formula
pOH = - log [ {OH}^{-} ]
We have

pOH = 7.09
Next we use the equation
pH = 14 - pOH
We have
pH = 14 - 7.09
We have the final answer as
<h3>6.91</h3>
Hope this helps you
I'm pretty sure its an electron. I hope this helps! (:
The balanced chemical reaction is:
HNO3 + NaOH = NaNO3 + H2O
We are given the amount and concentration of the reactants. The values given will be the starting point.
0.20 mol /L HNO3 (.015 L) (1 mol NaOH / 1 mol HNO3) = 0.003 mol NaOH
0.003 mol NaOH / 0.10 mol/ L NaOH = 0.03 L NaOH or 30 mL NaOH
According to the octet rule, atoms tend to gain, lose, or share electrons until they are surrounded by__8__ valence electrons.
