Converting Chemical Reactions to Equations

To convert the given chemical reactions into equations, we need to balance the number of atoms on both sides of the reaction. Let's go through each reaction one by one:

1) Na + O2 = Na2O

In this reaction, we have sodium (Na) reacting with oxygen (O2) to form sodium oxide (Na2O). To balance the equation, we need to ensure that the number of atoms on both sides is equal.

The balanced equation for this reaction is:

2Na + O2 = 2Na2O [[1]]

2) P + O2 = P2O5

In this reaction, we have phosphorus (P) reacting with oxygen (O2) to form phosphorus pentoxide (P2O5). To balance the equation, we need to ensure that the number of atoms on both sides is equal.

The balanced equation for this reaction is:

4P + 5O2 = 2P2O5 [[2]]

3) SiH4 + O2 = SiO2 + H2O

In this reaction, we have silane (SiH4) reacting with oxygen (O2) to form silicon dioxide (SiO2) and water (H2O). To balance the equation, we need to ensure that the number of atoms on both sides is equal.

The balanced equation for this reaction is:

SiH4 + 2O2 = SiO2 + 2H2O [[3]]

4) C2H6 + O2 = CO2 + H2O

In this reaction, we have ethane (C2H6) reacting with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). To balance the equation, we need to ensure that the number of atoms on both sides is equal.

The balanced equation for this reaction is:

2C2H6 + 7O2 = 4CO2 + 6H2O [[4]]
