<em>Calculate the pH of the following substances formed during a volcanic eruption:
</em>
<em>• Acid rain if the [H +] is 1.9 x 10-5
</em>
<em>• Sulfurous acid if [H +] = 0.10
</em>
<em>• Nitric acid if [H +] = 0.11</em>
<em />
<h3>Further explanation </h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
It's b. calcium
because the outer electron structure in all of that element is similar, they have the same chemical and physical properties.<span />

Answer:
I think its might be 1 because the ionic numbers for CA is +2 and for P its +3
Hexa- means six
"hexa-" and it is in front of the fluoride so that means we have 6 fluorines
Answer:xenon hexafluoride →
