I) Interpret the chemical equation in terms of quantitative aspect. C3H8(g) + 5O2(g)->3CO2(g) + 4H2O(1/ce)

ii) Then, interpret it in terms of qualitative aspect. ​

Quantitative aspect: one mole of propane reacts with five moles of oxygen ( combustion ) to produce three moles of carbon dioxide and four moles of water.

Qualitative aspect: A colourless gas ( propane ) burns with a blue flame ( combination ) to form a colourless gas that turns lime water milky and drops of colourless liquid that turn anhydrous copper (ii) oxide from blue to white.
