yarga [219]
Hello!

The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.

The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure
andriy [413]

Answer:

5.5 L

Explanation:

First we <u>convert 10 g of propane gas</u> (C₃H₈) to moles, using its <em>molar mass</em>:

  • 10 g ÷ 44 g/mol = 0.23 mol

Then we <u>use the PV=nRT formula</u>, where:

  • P = 1 atm & T = 293 K (This are normal conditions of T and P)
  • n = 0.23 mol
  • R = 0.082 atm·L·mol⁻¹·K⁻¹
  • V = ?

1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K

  • V = 5.5 L

Gasoline burning in an engine: Exothermic or Endothermic?
Alinara [238K]
An exothermic reaction releases heat. An endothermic reaction absorbs heat. Burning gas releases heat so it would be exothermic. Acid and water react heating the beaker would be exothermic because it releases heat from the reaction. Hope this helps! ;)
