Nitroglycerin, an explosive compound, decomposes according to the equation below. 4 c3h5(no3)3(s) 12 co2(g) + 10 h2o(g) + 6 n2(g) + o2(g) calculate the total volume of gases when collected at 1.2 atm and 25°c from 2.5 ✕ 102 g of nitroglycerin.

162.6 liter

Explanation:

1) Balanced chemical equation:

4 C₃H₅(NO₃)₃ (s) → 12 CO₂ (g) + 10 H₂O (g) + 6 N₂ (g) + O₂(g)

2) Convert 2.5 × 10² g of C₃H₅(NO₃)₃ into number of moles

molar mass of C₃H₅(NO₃)₃ = 227.0865 g/mol

number of moles = mass in grams / molar mass = 250 g / 227.0865 g/mol = 1.10 moles

3) Using proportion find the number of moles of each product:

1.10 moles C₃H₅(NO₃)₃ / 4 moles C₃H₅(NO₃)₃ × equation coefficient

i) CO₂:

12 ⇒ 1.10 / 4 × 12 = 3.3 moles

ii) H₂O:

10 ⇒ 1.10 / 4 × 10 = 2.75 mol

iii) N₂:

6 ⇒ 1.10 / 4 × 6 = 1.65 mol

iv) O₂:

1 ⇒ 1.10 / 4 × 1 = 0.275 mol

4) Total number of moles

3.3 mol + 2.75 mol + 1.65 mol + 0.275 mol = 7.975 mol of gas

5) Use ideal gases equation to find the volume

pV = nRT ⇒ V = nRT / p

V = 7.975 mol × 0.0821 atm×liter / K×mol × 298K / 1.2 atm = 162.6 liter

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
