yeep the answer is 3... i just took the k12 test rn
The concentration of the FeSO4 solution in molarity would be 0.4356
The concentration can be derived first by writing out the balanced equation of the reaction:
From the balanced equation: for every 1 mole of KMnO4, 5 moles of FeSO4 is needed for complete oxidation.
Recall that: mole = molarity x volume
Mole of KMnO4 needed = 0.1327 x 0.01642
= 0.002179 mole
1 mole KMnO4 = 5 mole FeSO4
0.002178 mole = 5 x 0.002178/1
= 0.01089 moles of FeSO4
Molarity of FeSO4 = mole/volume
= 0.01089/0.025
= 0.4356 M

<em>ANSWER:</em>
Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other. ... Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.
The least amount of energy required to activate atoms or molecules to a state in which they can undergo a chemical reaction.
