Answer:
<h2>pH = 4.44 </h2>
Explanation:
The pH of a substance can be found by using the formula
![p H = - log[ H^{ + } ]](https://tex.z-dn.net/?f=p%20H%20%20%3D%20%20-%20%20%20log%5B%20H%5E%7B%20%2B%20%7D%20%20%5D)
where [ H+ ] is the hydrogen ion concentration of the solution
From the question
[ H + ] = 3.60 × 10^-5 M
So the pH is

We have the final answer as
<h3>pH = 4.44 </h3>

Answer:
<u>K (Potassium) and Cl (Chlorine)</u>
Explanation:
Ionic bonds are formed with metals and nonmetals
Covalent bonds are formed only with nonmetals
Calcium and potassium are both metals
Sulfur and Chlorine are both nonmetals so they don't form ionic bonds
Carbon and Oxygen are both nonmetals so they don't form ionic bonds
