Answer: On heating, Magnesium forms its oxide; while potassium manganate(VII) decomposes
Explanation:
Magnesium Mg, on heating forms Magnesium oxide
2Mg(s) + O2(g) --> 2MgO
Potassium permanganate KMnO4, on heating decomposes to potassium manganate K2MnO4, manganese dioxide MnO2, and Oxygen gas O2.
2KMnO4 --> K2MnO4 + MnO2 + O2
The difference in observation is that, on heating, Magnesium forms its OXIDE as product; while potassium manganate(VII) decomposes, giving OFF most of its constituents and reducing its weight.

I believe the answer is A. <span>make a softer sound because the shark will not hear the softer signal.
</span><span>
I say this becasue "</span><span>Some of the sounds dolphins make are outside the range of human hearing." So that means the the dolphins speak at a higher wavelength then us humans and we can't hear it so they could use that to their advantage and speak at a height wavelength to each other when sharks are near.
I could be wrong, but I think the answer is A. </span>
