Answer:
because they emit liquid waste wich is later dumped into the ocean causing a lot of harm and many fatalities in sea life
Explanation:
Explanation:
The pH of a substance can be found by using the formula
![pH = - log[ H^{ + } ]](https://tex.z-dn.net/?f=pH%20%3D%20%20-%20%20log%5B%20H%5E%7B%20%2B%20%7D%20%20%5D)
where [ H+ ] is the hydrogen ion concentration in the substance
From the question
[ H+ ] = 2.1 × 10-¹² M
To find the pH substitute the value into the above formula
We have

We have the answer as
<h2>pH = 11.7 </h2>
The solution is basic since it lies in the basic region that is from 8 to 14
Hope this helps you
Answer:
105
Explanation:
Density = mass/volume
therefore volume = mass/density
826/7.9=105 (To three significant figure)
<h3>Yes</h3>
The copper itself can react with hydrogen
Here is the chemical reaction
2CuCl2(aq) + H2(g) -> 2CuCl(s) + 2HCl(g)
