Write a balanced equation for the combustion of liquid ethanol in air.

Chemistry

Katyanochek1 [597]3 years ago
7 0

<u>Answer:</u> The balanced chemical equation for the combustion of liquid ethanol is written below.

<u>Explanation:</u>

Combustion reactions are defined as the reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water. Heat is released during these reactions.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the combustion of liquid ethanol follows:

C_2H_5OH(l)+3O_2(g)\rightarrow 2CO_2(g)+3H_2O(g)

By Stoichiometry of the reaction:

1 mole of liquid ethanol reacts with 3 moles of oxygen gas to produce 2 moles of carbon dioxide gas and 3 moles of water vapor.

Hence, the balanced chemical equation for the combustion of liquid ethanol is written above.

The reaction is           2 NO (g) <----> N2(g) + O2

partial pressures

Initial                                 37.30          0          0

Change                            -2p                +p        +p

Equilibrium                          37.30-p        p          p

Kp = pN2 X pO2 / (pNO)^2

2400 = p^2 /  (37.30-p)^2

3339096 - 179040p + 2400p^2 = p^2

2399p^2 + 3339096  -179040 p = 0

On solving

p = 36.55atm

Thus partial pressure of N2 and O2 = 36. 55 atm

If 45.6 grams of water decompose at 301 Kelvin and 1.24 atmospheres, how many liters of oxygen gas can be produced? Show all of
Artyom0805 [142]

This reaction is called the electrolysis of water. The balanced reaction is:

 2H2O = 2H2 + O2

<span>
We are given the amount of water for the electrolysis reaction. This will be the starting point of our calculation.

45.6 grams H2O (1 mol H2O / 18.02 g H2O) (1 mol O2 / 2 mol H2O) = 1.27 mol O2

V = nRT/P = </span><span>1.27 mol O2 (0.08206 atm L / mol K) (301 K) / 1.24 atm
V = 25.20 L O2</span>

The boiling point of water is 100ºC. The boiling point of acetone is 56ºC. Which statement about distilling a mixture of acetone
Anika [276]

Answer:

I think  Acetone will be  captured and cooled.

Explanation:

Distillation is a method of separation based on the difference in boiling point of two liquids.

The liquid that has a lower boiling point is first separated from the mixture. It vaporizes, cooled and collected before the liquid that has a higher boiling point.

In this case, acetone is captured and cooled before water since it has a boiling point of 56ºC and water has a boiling point of 100ºC.
