Answer:

C2H6O(aq) + 3O2(g) → 2CO2(g) + 3H2O(l)

Explanation:

Step 1: data given

The reactants are:

ethanol = C2H6O(aq)

oxygen gas = O2(g)

The products are:

gaseous carbon dioxide = CO2(g)

liquid water = H2O(l)

Step 2: The unbalanced equation

C2H6O(aq) + O2(g) → CO2(g) + H2O(l)

Step 3: Balancing the equation

C2H6O(aq) + O2(g) → CO2(g) + H2O(l)

On the left side we have 2 time C (in C2H6O), on the right side we have 1x C (in CO2). To balance the amount of C on both sides, we have to multiply CO2 on the right side by 2.

C2H6O(aq) + O2(g) → 2CO2(g) + H2O(l)

On the left side we have 6x H (in C2H6O), on the right side we have 2x H(in H2O). To balance the amount of H on both sides, we have to multiply H2O on the right side by 3.

C2H6O(aq) + O2(g) → 2CO2(g) + 3H2O(l)

On the right side we have 7x O (4x O in 2CO2 and 3x O in 3H2O), on the left side we have 3x O (1x in C2H6O and 2x in O2). To balance the amount of O on both sides, we have to multiply O2 on the left side by 3. Now the equation is balanced.

C2H6O(aq) + 3O2(g) → 2CO2(g) + 3H2O(l)

Answer:

C₂H₆O + 3 O₂ → 2 CO₂ + 3 H₂O

Explanation:

Ethanol (C₂H₆O) is processed by the body when reacts with oxygen (O₂) producing carbon dioxide (CO₂) and water (H₂O). The unbalanced reaction is:

C₂H₆O + O₂ → CO₂ + H₂O

As you can see, ethanol contains 2 atoms of carbon, that means must be produced 2 CO₂:

C₂H₆O + O₂ → <em>2</em> CO₂ + H₂O

Also, ethanol contains 6 atoms of hydrogen that produced 3 molecules of water:

C₂H₆O + O₂ → <em>2</em> CO₂ + <em>3</em> H₂O

Now, with carbon and hydrogen balanced, there are produced 7 atoms of oxygen. As ethanol contains 1 atom of oxygen. 3 moles of O₂ must react in the beginning. Thus, balanced reaction is:

C₂H₆O + <em>3</em> O₂ → <em>2</em> CO₂ + <em>3</em> H₂O

The best way seperate salt fron wateris with the use of
ExtremeBDS [4]

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid. So, I would say maybe oil.
