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

Why glucose and fructose produce same shaped products with phenylhydrazine?
NemiM [27]

During the reaction of glucose and fructose with excess phenylhydrazine to form osazone, only the C-1andC-2 atoms of glucose and fructose participate in the reaction. The rest of the molecule remains intact. Hence, glucose and fructose produce the same osazone.

The teacher made a 0.5M solution. How is this number read/said?
lukranit [14]

Answer:

It reads as follows: 0.5 moles of solute per liter of solution.

Explanation:

Molarity is the most frequent way of expressing the concentration of solutions in chemistry, and it indicates the number of moles of solute dissolved per liter of solution; is represented by the letter M.

An inexpensive and accurate method of measuring the quantity of electricity flowing through a circuit is to pass the current thr
Paha777 [63]

Total of 127.013 C of charge is passed

Given

 weight of Ag solution before current has passed = 1.7854 g

  weight of Ag solution after current has passed = 1.8016 g

  Molecular mass of Ag = 107.86 g

  Faraday's Constant = 96485

First of all we have to apply Faraday's First Law of Electrolysis i.e

         m = ZQ

  where

Z is propotionality constant (g/C)

Q is charge (C)

Hence,

 Z = Atomic mass of substance/ Faraday's Constant

    = \frac{107.86 g}{96485 C}

    = 0.0011178 g/C

Now ,

   change in mass before and after the passing of current (Δm)

       Δm = 1.8016g-1.7854g

             =   0.0162g

    Now  amount of coulombs passed = \frac{0.142g}{0.0011178 g/C }

          amount of coulombs passed = 127.03524 C

Thus from the above conclusion we can say that amount of coulombs have passed is 127.03524 C

What is a common property of metals?
Y_Kistochka [10]

Answer:

B) conducts electricity

Explanation:

Metals are conductors, literally meaning they conduct electricity.

One metal is liquid at room temp (there might be one more but I only know of mercury).

The reactivity depends on the placement in the periodic table.

If it conducts electricity, it can't be an insulator.
