Sucrose (C12H22O11) can be assorted with potassium nitrate to form an amateur rocket propellant called rocket candy, which, despite its name, is at least mildly toxic. Define The properly balanced mixture reacts to form K2CO3, N2, H2O and CO2. State the balanced reaction and determine the mass of KNO3 that must be mixed with 1.9 g of sugar to produce optimally balanced rocket candy.
