Answer:
5.2 ×10^-4 moles
Explanation:
Equation of reaction:
5C2O4^2- + 2MnO4^- +. 6H^+. ----------> 10CO2. +. 8H2O. + 2Mn^2+
From the information provided in the question:
Volume of potassium permanganate= 34.88ml
Concentration of potassium permanganate= 0.015M
Amount potassium permanganate= 0.015 × 34.88/1000= 5.2 ×10^-4 moles
I believe the answer is D. The atmosphere, different layers of the atmosphere can help in different ways! The stratosphere helps protect us from the sun's rays; The Mesophere is what helps protect us from meteorites! It's so cold that they burn up in that area.
