Question

Using the balanced reaction below, drag and drop the terms into the correct location to solve the following problem:

If 1.5 moles of ethanol (C2H5OH) react, how many moles of water will be formed?

2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O

Answer 1

4.5 moles of H2O.

Step-by-step explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

C2H5OH + 3O2 —> 2CO2 + 3H2O

From the balanced equation above,

1 moles of C2H5OH reacted to produce 3 moles of H2O.

Finally, we shall determine the number of mole of H2O produced by the reaction of 1.5 moles of C2H5OH. This can be obtained as follow:

From the balanced equation above,

1 moles of C2H5OH reacted to produce 3 moles of H2O.

Therefore, 1.5 moles of C2H5OH will react to produce = 1.5 × 3/ 1 = 4.5 moles of H2O.

Thus, 4.5 moles of H2O will be produced.
