Given the reaction C + O2 ---> CO2 which pair of reactions represents the two half-reactions?
Daniel [21]
<h3><u>Answer;</u></h3>

C → CO₂ + 4e₋

O₂ + 4e₋→ CO₂

<h3><u>Explanation</u>;</h3>
  • Given the reaction  C + O2 ---> CO2
  • During the formation of a carbon dioxide molecule, the carbon atom shares four electrons with the oxygen atom on the left and four electrons with the oxygen atom on the right.
  • This means there will be eight electrons around each atom. Two pairs of electrons shared between two atoms make a double bond between the atoms, which is represented by a double dash.

Balance the chemical equation below: CO2 + H2O + 2678 kJ-&gt; C6H1206 + O2 a. How many moles of H20 are involved in this reactio
11Alexandr11 [23.1K]

Answer:

a) 6 mol H2O

b) this reaction is endothermic

c) when 1 mol of CO2 is used, in the reaction they occur 0.5025 KJ

Explanation:

balanced eq:

  • 6CO2 + 6H2O + 2678 KJ ↔ C6H12O6 + 6O2

                                         6 - C - 6

                                         18 - O - 18

                                          12 - H - 12

a) mol H2O = 6 mol.......from balanced equation.

b) ΔE = 2678 KJ....... this reaction absorbs heat ( ΔE is positive )

c)    1 gramo C6H12O6 ≅ 4 cal

  • Mw C6H12O6 = 180.156 g/mol

⇒ 1mol CO2 * ( mol C6H12O6 / 6mol CO2 ) =0.166 mol C6H12O6

⇒ 0.166mol C6H12O6 * ( 180.156 g C6H12O6 / mol ) = 30.026g C6H12O6

⇒30.026 gC6H12O6 * ( 4 cal / gC6H12O6 ) * ( Kcal / 1000 cal ) * (4184 J / Kcal ) * ( KJ / 1000 J ) = 0.5025 KJ C6H12O6.
