gogolik [260]

Answer:

First Method: Vacuum Distillation and Chromatographic separation of the remains that were precipitated out from the peel.

Second Method: Extraction of components from orange peels by help of precipitation procedures that are mostly done <em>In Situ. </em>Those components can be recovered using the saponification process.

(CH3)2N2H2 + N2O4 → N2 + H2O + CO2 + heat [balance?]​
Rasek [7]
<h3>Answer:</h3>

2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

<h3>Explanation:</h3>
  • Balancing chemical equations involves putting coefficients on reactants and products.
  • This results in an equal number of atoms of each element on either side of the equation.
  • Balancing chemical equations ensures that the law of conservation of mass is obeyed.
  • According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products which is done by balancing chemical equations.
  • Putting the coefficients, 2, 3, 4, 4, 4 on the equation makes the equation balanced.
  • Therefore, the balanced equation would be;

       2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat
