Kindly Help Please! Can you write the symbol equations for each of the reactions below:
and Can you balance them?

1) Ethane + Oxygen = Carbon Dioxide + Water

2) Butane + Oxygen = Carbon Dioxide + Water

3) Octane + Oxygen = Carbon Dioxide + water

4) Decane + Oxygen = Carbon Dioxide + Water

thank you!​

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical reactions will be:

1) Ethane + Oxygen = Carbon Dioxide + Water :

2) Butane + Oxygen = Carbon Dioxide + Water :

3) Octane + Oxygen = Carbon Dioxide + water:

4) Decane + Oxygen = Carbon Dioxide + Water :  

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
