Ok so the PH for each solution will be
<span>1.) 1.638
2.) 5.2
3.) 12.524
This is found using the formula: </span> pH<span> = - log [H</span>3O+].
And the pOh for each one will be
<span>1.) 12.362
2.) 8.8
3.) 1.4763
This is found by the formula </span>pOH = -log10[OH-<span>]
</span>Hope this is useful
Answer:
the answer is 'a'
Explanation:
When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids. They then fall back to earth as acid rain. Wind often carries acid rain far from the pollution source.
Given that the equipment is stationary, we should remove particles (such as food and soil) from around the equipment.
This step ensures that large particles are removed and do not hinder the remaining process of cleaning. After doing so, the next step is to remove the removable parts of the machinery. After this has been done, the cleaning steps may be undertaken.
I think the correct answer would be B. The process of electroplating uses a direct current in order to give a cheap metal the apperance and resistance of a more expensive metal by coating it with a certain metal. The current reduces the dissolved metal ions to form a thin coating on a surface.
