[Verse 1]
Mole ratios locked, the equation's balanced tight
Hydrogen and oxygen combusting through the night
Two H-two plus one O-two, that's the ratio we keep
Water vapour out the nozzle at two thousand degrees
Stoichiometry means counting every atom in the chain
Conservation of mass — what goes in must come out again
Enthalpy drops negative, exothermic means release
The system sheds its thermal load, the delta-H decreased
Adiabatic flame temperature — no heat lost to the wall
All the energy stays local, maximum thermal haul
Hydrogen burns at nearly three thousand Kelvin clean
The hottest controlled combustion that you've ever seen
[Chorus]
Chimica del fuoco — chemistry of flame
Ogni reazione ha un costo, nothing burns the same
Conta gli atomi, balance the equation right
Entalpia negativa — exothermic ignite
Chimica del fuoco, we calculate the mass
Mole per mole, propellant through the nozzle fast
[Verse 2]
Cryogenic fluids — liquid at a cost
Below minus two-fifty or the hydrogen is lost
Liquid oxygen sits cold at minus one-eight-three
Liquid methane needs minus one-six-one degrees
Density triples when you chill the gas to liquid phase
More propellant in the tank, more thrust across the haze
But handle them with caution — thermal gradients crack the seals
Boil-off steals your margins, vapour pressure always steals
[Chorus]
Chimica del fuoco — chemistry of flame
Ogni reazione ha un costo, nothing burns the same
Conta gli atomi, balance the equation right
Entalpia negativa — exothermic ignite
Chimica del fuoco, we calculate the mass
Mole per mole, propellant through the nozzle fast
[Verse 3]
Materials chemistry — the rocket eats itself
Liquid oxygen corrodes what's sitting on the shelf
Compatibility matters — oils and lubricants ignite
Hydrocarbon contamination sparks an unseen fight
Hydrogen embrittlement — a rare and vicious flaw
The word means metal lattice cracked by hydrogen withdraw
Tiny atoms diffuse through the steel's crystalline grain
Weakening the structure till the vessel splits in twain
Passivation layers guard aluminium from the rust
Anodised and coated — every surface earned its trust
[Bridge]
Pyrexia — excess thermal saturation in the wall
Ablative liners char and sacrifice before they fall
Every molecule accounted for, no slack in the chain
Thermodynamics doesn't negotiate — respect the domain
Specific impulse measures how efficiently you burn
Seconds of momentum per unit mass — the metric you must learn
[Chorus]
Chimica del fuoco — chemistry of flame
Ogni reazione ha un costo, nothing burns the same
Conta gli atomi, balance the equation right
Entalpia negativa — exothermic ignite
Chimica del fuoco, we calculate the mass
Mole per mole, propellant through the nozzle fast
[Outro]
Balance your equations, watch the enthalpy sign
Cryo temps and delta-H, keep every number aligned
Corrosion won't forgive you, embrittlement won't wait
Chimica precisa — calculate before it's too late
