The following chemical equation describes a reaction that will give you fireworks. But it isn't balanced. Please balance it, and use the stoichiometric coefficients you'll have after solving the equation as the password to buy Sirius.
"KNO3 + C7H40 + S → K2CO3 + K2SO4 + K2S + CO2 + CO + H20 +N2"
Go! We need fireworks to celebrate the Fourth of July
