7. Anthropogenic CO2 Sources

Question 1

Hydrocarbons are fossil fuels.

What is the formula for hydrocarbon?

Answer 1

C_XH_Y

Question 2

The general equation fo combustion of hydrocarbon is:

Answer 2

C_XH_Y + O₂ ⇒ CO₂ + H₂O

Question 3

What is the formula for finding the volume of a gas(at 24.5L 25 degrees, 1atm)?

Answer 3

V= n x mV

Where:

V= volume

n= number of moles(ratio)

mV= molar voume (always 24.5L)

Question 4

Temperature and pressures are not likely to be 25 degrees or 1atm. THerefore use the Ideal Gas Law.

Which is:

Answer 4

PV = nRT

Where:

P= pressure in atm

V= volume in L

n= number of moles (ratio)

R= universal gas constant (0.8206Latm/molK)

T= temperature in kelvin

Question 5

How do you find temperature in kelvin?

Answer 5

T (K)= T^oC + 273

Question 6

What is the universal gas constant’s value and symbol?

Answer 6

R= universal gas constant (0.8206L atm/molK)
