Count up the number of electrons in each orbital. theres ten electrons which means it has 10 protons. the element would be neon
Answer:
The products are CO₂ and H₂O.
The ballanced equation is this:
2C₄H₆ + 11O₂ → 8CO₂ + 6H₂O
Explanation:
In any chemical reaction, where you see that you have a compound reacting only with oxygen (O₂), you are in front of combustion.
Products in combustion are always water vapor and carbon dioxide.
Take a look to the methane combustion.
CH₄ + 2O₂ → CO₂ + 2H₂O
1 mol of methane reacts with 2 moles of oxygen to form 1 mol of CO₂ and 2 moles of water.
This is the combustion for an alkene where 2 moles of the alkene reacts with 11 moles of oxygen to make water and CO₂ like this:
2C₄H₆ + 11O₂ → 8CO₂ + 6H₂O
