The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

Answer:
There will be 0.825 grams of CO2 produced
Explanation:
Step 1: Data given
Mass of water formed = 0.45 grams
Molar mass of water = 18.02 g/mol
Molar mass of CO2 = 44.01 g/mol
Step 2: The balanced equation
C3H8 + 5O2 → 4H2O + 3CO2
Step 3: Calculate moles of water
Number of moles water = mass of water / molar mass water
Number of moles water = 0.45 grams / 18.02 g/mol
Number of moles water = 0.025 moles
Step 4: Calculate moles of CO2
For 1 mol of propane we need 5 moles of O2 to produce 4 moles of H2O and 3 moles of CO2
When 0.025 moles of H2O are produced, we'll get 3/4 * 0.025 = 0.01875 moles of CO2 produced
Step 5: Calculate mass of CO2 produced
Mass of CO2 = moles of CO2 * molar mass of CO2
Mass of CO2 = 0.01875 moles * 44.01 g/mol
Mass of CO2 = 0.825 grams
There will be 0.825 grams of CO2 produced
