What else is produced during the combustion of butane, C4H10?<br><br> 2C4H10 + 13O2 → <br> + 10H2O
Neko [114]
<h3>Answer:</h3>

8CO₂

<h3>Explanation:</h3>

We are given;

  • Butane, C₄H₁₀
  • Butane is a hydrocarbon in the homologous series known as alkane.

We are required to determine the other product produced in the combustion of butane apart from water.

  • We know that the complete combustion of alkane yields carbon dioxide and water.
  • Therefore, combustion of butane will yield carbon dioxide and water.
  • The balanced equation for the complete combustion of butane will be;

       2C₄H₁₀ + 13O₂ →  8CO₂ + 10H₂O

Elemental calcium reacts with water at room temperature to form calcium hydroxide and hydrogen gas as shown in this equation. So
dem82 [27]
Reaction of Elemental Calcium with Water is as follow,

                        Ca  +  2 H₂O    →    Ca(OH)₂  +  H₂↑

When Sodium Metal is reacted with Water it produces NaOH and eliminates Hydrogen gas as shown in following equation,

                         2 Na  +  2 H₂O    →    2 NaOH  +  H₂↑

In both cases corresponding Hydroxides along with Hydrogen gas is produced.
