How many molecules of co2, h2o, c2h5oh, and o2 will be present if the reaction goes to completion?

Molecules of CO₂, H₂O, C₂H₅OH, and O₂ will be present if the reaction goes to completion are

0 molecules C₂H₅OH

0 O₂ molecules

2 and CO₂ molecules

3 H₂O molecules

The reaction equation is the chemical formula of reagents and product substances

the reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Steps in equalizing the reaction equation:

The reaction of the combustion of hydrocarbons with oxygen produces CO₂ and H₂O (water vapor). can use steps:

Balancing C atoms, H and last atoms O atoms

Equivalent reaction equation, if the number of atomic substances of the reactor is the same as the product substance

The reaction coefficient also shows the ratio of moles, volumes or molecules of substances involved in the reaction

Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.

If O₂ is insufficient there will be incomplete combustion resulting in CO and H₂O

In perfect combustion of ethanol (C₂H₅OH) and oxygen (O₂), ethanol and oxygen will be converted entirely into CO₂ and H₂O at the end of the reaction

Ethanol and oxygen reactions:

C₂H₅OH + O₂ ---> CO₂ + H₂O

We equalize first by giving coefficients a, b and c

C₂H₅OH + aO₂ ---> bCO₂ + cH₂O

C = left 2, right b -> b = 2

H = left 6, right 2c ---> c = 3

O = left 2a + 1, right 2b + c

2a + 1 = 2 (2) + 3

2a + 1 = 4 + 3

2a = 6

a = 3

So the equivalent reaction equation =

C₂H₅OH + 3O₂ ---> 2CO₂ + 3H₂O

The comparison of the coefficients shows that: 1 C₂H₅OH molecule reacts with 3 molecule O₂ produces 2 molecules of CO₂ and 3 molecules of H₂O

So the complete combustion of ethanol at the end of the reaction composition:

0 molecules C₂H₅OH

0 O₂ molecules

2 and CO₂ molecules

3 H₂O molecules

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
