B.2C2H6 + 5O2 >2CO2 +3H2O
Answer:
See below
Explanation:
The atmosphere of the earth hundreds of millions of years ago was only water vapour and carbon, both from the one ocean that existed around the continental body of Pangea. The photosynthesis process and exache (⊕) caused the percentages to decrease.
Answer:
T = 1031.30 K
Explanation:
Given data:
Temperature of gas = ?
Number of moles of gas = 0.014 mol
Volume of balloon = 1.20 L
Pressure of gas = 0.988 atm
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
T = PV/nR
T = 0.988 atm × 1.2 L / 0.014 mol × 0.0821 atm.L/ mol.K
T = 1.186 atm. L / 0.00115 atm.L/K
T = 1031.30 K
