balance the equation and name the reaction taking place

C3H5OH+O2 equals CO2+ H2O

I wonder if you meant C2H5OH, ethanol. However, here is the balanced equation for your post.

C3H5OH + 4O2 ==> 3CO2 + 3H2O

To balance the equation C3H5OH + O2 → CO2 + H2O, you need to ensure that the number of atoms of each element is the same on both sides of the equation.

First, let's count the number of atoms for each element:
C: 3 on the left, 1 on the right
H: 8 on the left, 6 on the right
O: 2 on the left, 3 on the right

To balance the equation, you can start by balancing the carbon atoms first. Place a coefficient of 3 in front of CO2 to balance the carbon atoms:
C3H5OH + O2 → 3CO2 + H2O

Now, let's balance the hydrogen atoms. Place a coefficient of 6 in front of H2O to balance the hydrogen atoms:
C3H5OH + O2 → 3CO2 + 3H2O

Finally, let's balance the oxygen atoms. There are 10 oxygen atoms on the right side, so place a coefficient of 5/2 (or 2.5) in front of O2 to balance the oxygen atoms:
C3H5OH + 5/2 O2 → 3CO2 + 3H2O

To get rid of the fractional coefficient, you can multiply everything by 2:
2C3H5OH + 5O2 → 6CO2 + 6H2O

The balanced equation is:
2C3H5OH + 5O2 → 6CO2 + 6H2O

The reaction taking place is the combustion of ethanol, also known as ethyl alcohol, with oxygen to produce carbon dioxide and water.

To balance the equation C3H5OH + O2 → CO2 + H2O, we need to make sure that the number of atoms on both sides of the equation are equal.

Let's start by balancing the carbon (C) atoms. There are 3 carbon atoms on the left side and only 1 carbon atom on the right side, so we need to place a coefficient of 3 in front of CO2 on the right side.

C3H5OH + O2 → 3CO2 + H2O

Next, let's balance the hydrogen (H) atoms. There are 8 hydrogen atoms on the left side and only 2 hydrogen atoms on the right side, so we need to place a coefficient of 4 in front of H2O on the right side.

C3H5OH + O2 → 3CO2 + 4H2O

Finally, let's balance the oxygen (O) atoms. There are 2 oxygen atoms in C3H5OH and none on the right side, so we need to place a coefficient of 2 in front of O2 on the left side.

2C3H5OH + O2 → 3CO2 + 4H2O

Now the equation is balanced, with 6 carbon atoms, 12 hydrogen atoms, and 10 oxygen atoms on both sides.

As for the name of the reaction, the balanced equation represents the combustion of C3H5OH (ethanol) in the presence of oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O). This is a combustion reaction.
