The balanced equation that shows the reaction between oxalic acid and permanganate ion in an acidic medium is: 2MnO4- + 5H2C2O4 + 6H+ -> 2Mn(2+) + 10CO2 + 8H2O. Thus, 1 mole of oxalic acid reacts with 0.4 mole of permanganate ion. This was obtained using stoichiometry:
1 mol H2C2O4 x (2 mol MnO4-/ 5 mol H2C2O4) = 0.4 mol MnO4-
In this redox reaction, the permanganate is reduced to manganese(II) ion.
Answer:
So for your question, the Periodic Table tells us that sodium has an Atomic Number of 11, so there are 11 protons and 11 electrons. The Periodic Table tells us that sodium has an Atomic Mass of ≈23. So there are 23 - 11 = 12 neutrons.

Answer:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
Explanation:
Answer:
A. 145.2 g NH3
B. 0.76 g H2
C. 1.41 x 10^22 molecules NH3
Explanation:
A. 1 mol N2 -> 2 mol NH3
4.27 mol N2 -> x
x= (4.27 mol N2 * 2 mol NH3)/1 mol N2 x= 8.54 mol NH3
1 mol N2 -> 17 g
8.54 mol N2 -> x x= 145.2 g NH3
B.
2 g H2 -> 34 g NH3
x -> 13.01 g NH3
x= 0.76 g H2
C.
2 g H2 -> 34 g NH3
0.0235 g H2 -> x
x= 0.39 g NH3
0.39 g NH3 (1 mol NH3/17 g NH3)(6.023 x 10^23 molecules/1 mol NH3) =
1.41 x 10^22 molecules NH3
