Answer:
NO3− ions will not oxidize Mn2+ to MnO4− under standard state conditions.
Explanation:
The reduction potential of NO3^- is +0.96V while the reduction potential of MnO4^- is +1.51V. Hence looking at the reduction potential values stated above, NO3^- will not oxidize Mn^2+ to MnO4^-.
The MnO4^- having a greater reduction potential will be reduced to Mn^2+ while NO3^- will be oxidized to NO.
From the basics conversions:
1 nanogram is equivalent to 1 * 10^-15 megagrams
To convert 7.02 * 10^-10 nanograms to megagrams, all you have to do is cross multiplication as follows:
1 nanogram ................> 1 * 10^-15 megagrams
7.02 * 10^-10 nanograms ...............> ?? megagrams
megagrams = (7.02*10^-10 * 1*10^-15) / (1) = 7.02 * 10^-25 megagrams
Gas is the most compressible because the atoms have more space in between. solids on the other hand, are the least compressible because their atoms are really closely packed.
