Answer:
The answer to your question is 308.1 g of KmNO₄
Explanation:
Data
Volume = 6 L
Concentration = 0.325 M
Molar mass of Potassium permanganate = 39 + 55 + (16 x 4) = 158 g
Process
1.- Calculate the moles of KMnO₄
Formula
Molarity = moles/volume
moles = molarity x volume
moles = 0.325 x 6
moles = 1.95
2.- Calculate the grams of KMnO₄
158 g KMnO₄ ------------------ 1 mol
x ------------------ 1.95
x = (1.95 x 158)/1
x = 308.1 g

Answer:
• A candle is burned
• Your silver teapot turns black
• Two clear colorless salt solutions are mixed and a bright orange precipitate forms.
Explanation:
A chemical change results from a chemical reaction of the species involved. Examples of chemical changes are burning, cooking, rusting etc.
Physical change when matter changes forms but not chemical identity. Examples of physical changes are boiling, melting, freezing, evaporation etc.
