Question

Будь ласка допоможіть, C2H6+O2, Al+O2

Answer 1

Ответ:

2C2H6+7O2 → 4CO2+6H2O

4Al+3O2 → 2Al2O3

Answer 2

C2H6 + O2: The chemical equation C2H6 + O2 represents the reaction between ethane (C2H6) and oxygen (O2). This reaction is a combustion reaction, where ethane reacts with oxygen to produce carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is:

2C2H6 + 7O2 -> 4CO2 + 6H2O

In this equation, two molecules of ethane react with seven molecules of oxygen to produce four molecules of carbon dioxide and six molecules of water. This reaction releases a large amount of energy in the form of heat and light.

Al + O2: The chemical equation Al + O2 represents the reaction between aluminum (Al) and oxygen (O2). This reaction is also a combustion reaction, where aluminum reacts with oxygen to produce aluminum oxide (Al2O3). The balanced chemical equation for this reaction is:

4Al + 3O2 -> 2Al2O3

In this equation, four atoms of aluminum react with three molecules of oxygen to produce two molecules of aluminum oxide. This reaction also releases a significant amount of energy.
