C2H4 is the chemical formula for ethylene, a hydrocarbon gas that is used in the production of various plastics, including polyethylene.
This balances, but I'm not sure if it is realistic because there a number of different possibilities with the types of alkanes and alkenes produced. C21H44 = C8H18 + 2C2H4 + 3C3H6
To balance the chemical equation, you would need to change it to: 2C2H4 -> 4C + 4H2. This balances the number of atoms of each element on both sides of the equation, ensuring the law of conservation of mass is obeyed.
The chemical equation is:C10H22----------------C8H18 + C2H4
c4h10=2c2h4 +h2
This balances, but I'm not sure if it is realistic because there a number of different possibilities with the types of alkanes and alkenes produced. C21H44 = C8H18 + 2C2H4 + 3C3H6
Four: 2x2 = 4 C atoms in 2C2H4 (= two molecules C2H4)
To balance the chemical equation, you would need to change it to: 2C2H4 -> 4C + 4H2. This balances the number of atoms of each element on both sides of the equation, ensuring the law of conservation of mass is obeyed.
