Katyanochek1 [597]

Answer:

m_{MnO_2}=1.378gMnO_2

Explanation:

Hello,

In this case, we first apply the ideal gas equation to compute the moles of produced chlorine:

n_{Cl_2}=\frac{PV}{RT}=\frac{765 Torr*\frac{1atm}{760Torr}*0.385L}{0.082\frac{atm*L}{mol*K}*298.15K} =0.01585molCl_2

Then, by considering the given reaction, applying the stoichiometry, that shows a 1 to 1 relationship between chlorine and manganese dioxide, we find:

m_{MnO_2}=0.01585molCl_2*\frac{1molMnO_2}{1molCl_2} *\frac{86.937gMnO_2}{1molMnO_2} \\m_{MnO_2}=1.378gMnO_2

Best regards.

Balance the chemical equation. (Blank) N2O3 → (Blank) N2 + (Black) O2
Anna71 [15]

  The balanced equation is as below

 2 N₂O₃ →  2N₂ + 3O₂

<u><em> Explanation</em></u>

According  to the law  of mass conservation the  number of atoms  in reactants side must  be equal  the to the number of atoms in products  side.

 Therefore the  balanced reaction  above is balanced  since the number of atoms  in reactants side  are equal to number of atoms in products side.

For  there 4 atoms  of N   in reactants  side and  4 in products side.
