Balance the following chemical equation.​​​​​​​(2)
Angelina_Jolie [31]

Balanced chemical equation:

2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)

Explanation:

The correct chemical reaction is:

C₃H₆N₆ (l) + O₂ (g) → CO₂ (g) + H₂O (g) + N₂ (g)

To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.

Balanced chemical reaction:

C₃H₆N₆ (l) + (9/2) O₂ (g) → 3 CO₂ (g) + 3 H₂O (g) + 3 N₂ (g)

To have integer numbers we multiply the equation with 2 to obtain:

2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)

For the reaction 2Fe + O2 = 2FeO, how many grams of iron oxide are produced from 8.00 mol of iron? when o2 is an excess
Yanka [14]

Answer:

The answer to your question is 576 grams of FeO

Explanation:

Balanced chemical reaction

                      2Fe  +  O₂  ⇒  2 FeO

       Reactant             Elements         Products

             2                         Fe                     2

             2                         O                       2

Data

mass of FeO = ?

moles of Fe = 8

Excess Oxygen

Process

1.- Convert moles of Fe to grams

Atomic mass = 56 g

                         56 g of Fe ------------------ 1 mol

                           x               ------------------ 8 moles

                           x = (8 x 56) / 1

                           x = 448 g of Fe

2.- Use the coefficients of the balanced reaction to find the grams of FeO.

Molecular mass of FeO = 2[ 56 + 16]

                                       = 144 g

               2(56) g of Fe ----------------------- 144 g of FeO

               448 g             -----------------------  x

                x = (448 x 144) / 2(56)

                x = 64512 / 112

               x = 576 grams of FeO
