Answer:
The aroma from a lighted scented candle is released through the evaporation of the fragrance from the hot wax pool and from the solid candle itself. Like unscented candles, properly-formulated scented candles will primarily produce water vapor and carbon dioxide when burned
Explanation:
Answer:
294.2g
Explanation:
C3H8 + 5O2 —> 3CO2 + 4H2O
Molar Mass of C3H8 = (3x12) + (8x1) = 36 + 8 = 44g/mol
Molar Mass of O2 = 16x2 = 32g/mol
Mass of O2 from the balanced equation = 5 x 32 = 160g
From the equation,
44g of C3H8 was completely consumed by 160g of O2.
Therefore, 80.9g of C3H8 will be consume by = (80.9x160)/44 = 294.2g of O2
Therefore, 294.2g of O2 is needed
Answer: entropy
Explanation:
Entropy is the measure of degree of randomness or disorder of the system.
Bond energy is the energy possessed by a substance by virtue of its bonding of electrons
Enthalpy is the amount of energy absorbed or released in a chemical reaction.
Internal energy is the energy possessed by a body by virtue of rotational, vibrational and transitional modes.
Heat flow is the phenomenon of thermal equilibrium in which heat flows from hotter body to colder body to maintain equilibrium temperature.
Plate motion moves rock formations. Subduction moves rock down, below earths outer layer.
