Question

The blanks before the elements are supposed to be where numbers go. For example, 5 Cl2 (g). I need help filling out the blanks and the types of reaction it causes.

Balance Reaction A: Cl2 (g) + AlBr3 (aq) → Br2 (aq) + AlCl3 (aq)

Type of Reaction:

Balance Reaction B: C (s) + O2 (g) → CO3 (g)

Type of Reaction:

Balance Reaction C: PbBr2 (aq) + Al2O3 (aq) → PbO (aq) + AlBr3 (aq)

Type of Reaction:

Balance Reaction D: C4H10 (g) + O2 (g) → CO2 (g) + H2O (g)

Type of Reaction:

Balance Reaction E: K2CO3 (s) → K (s) + C (s) + O2 (g)

Type of Reaction:

Answer 1

3 Cl₂ (g) + 2 AlBr₃ (aq) → 3 Br₂ + 2 AlCl₃

Reaction type: Single displacement

2 C (s) + 3 O₂ (g) → 2 CO₃ (g)

Reaction type: Synthesis

3 PbBr₂ (aq) + Al₂O₃ (aq) → 3 PbO (aq) + 2 AlBr₃ (aq)

Reaction type: Double displacement

Balance Reaction: 2 C₄H₁₀ (g) + 13 O₂ (g) → 8 CO₂ (g) + 10 H₂O (g)

Reaction type: Complete combustion

Balance Reaction: 2 K₂CO₃ (s) → 4 K (s) + 2 C (s) + 3 O₂(g)

Reaction type: Decomposition

Step-by-step explanation:

For the first equation, the reaction type follows the single displacement format of

AX + B → A + BX

The second equation satisfies the reaction type for synthesis, which is

A + B → AB

The third equation satisfies double displacement, in which

AX + BY → AY + BX

The fourth equation is a complete combustion, as the equation yields CO₂ and H₂O as products

The last equation is a decomposition, which satisfies

AB → A + B

Hope this helps!!
