c) Nitrate has 14 mg of N per 62 mg of NO3
<u>Carbon</u>
Carbonate has 12 mg of C per 60 mg of
Bicarbonate has 12 mg of C per 61 mg of
The mass of nitroglycerin : 34.52 g
<h3>Further explanation</h3>Reaction
4C₃H₅N₃O₉ ⇒ 12 CO₂ + 10H₂O + 6N₂ +O₂
Volume = 10 L
Temperature = -5°C=268 °K
Pressure = 1 atm
mol of CO₂ (ideal gas) :
mol ratio C₃H₅N₃O₉ : mol CO₂= 4 : 12, so mol C₃H₅N₃O₉ :
mass C₃H₅N₃O₉ (MW=227,0865 g/mol):
Answer:
The activation energy of the reaction is 1.152 kJ/mol.
Explanation:
Activation energy is the minimum amount which is absorbed by the reactant molecules to undergo chemical reaction.
Initial temperature of reaction =
Final temperature of reaction =
Initial rate of the reaction at 100 k =
Final rate of the reaction at 200 k =
Activation energy is calculated from the formula:
R = Universal gas constant = 8.314 J/ K mol
