Balance the reaction below
__ C2H4 + ___ O2 → ___ CO2 + ___ H2O

Hey there!

C₂H₄ + O₂ → CO₂ + H₂O

First let's balance C.

There are 2 on the left and 1 on the right. So, let's add a coefficient of 2 in front of CO₂.

C₂H₄ + O₂ → 2CO₂ + H₂O

Next let's balance H.

There are 4 on the left and 2 on the right. So, let's add a coefficient of 2 in front of H₂O.

C₂H₄ + O₂ → 2CO₂ + 2H₂O

Lastly, let's balance O.

There are 2 on the left and 6 on the right. So, let's add a coefficient of 3 in front of O₂.

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

Here is our final balanced equation.

Hope this helps!

answer; capital earns interest; entrepreneurship receives a profit or incurs a loss;

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
