a)dry the affected area with paper towels.
b)sprinkle the affected area with powdered Na2SO4

e)flush the affected area with water and then with dilute vinegar solution.</p>

<p>2.in the following chemical reaction the oxidizing agent is
5H2O2+2MnO4+6H->2Mn+8H2O+5O2
a)H2O2 b)MnO4 c)H d)Mn e)O2</p>

<p>im begging you..</p>

<ol>
<li>C</li>
<li>D i think</li>
</ol>

3

<p>im not sure if its d or e for number 2...but thank you for advice tho..</p>

<p>anyone who is sure about this?</p>

4

<p>An oxidiziing agent is the element which gets reduced in the reaction. In this case, the charge on the Manganese goes from a +7 to 0. Therefore, it gets reduced, and therefore, Manganese is the reducing agent.</p>

5

<p>I think number 1 is D.....</p>
