Answer: 2C4H10(g) + 13O2(g)----->8CO2(g) + 10H2O(g)

Explanation:

From the general formula for combustion of alkanes:

CnH2n+2 + 3n+1/2 O2------------> nCO2 + (n+1)H2O

We have:

C4H10(g) + 13/2 O2(g) ---------> 4 CO2(g) + 5H2O(g)

Now we can multiply by 2 to obtain the lowest whole number coefficients

2C4H10(g) + 13O2 (g) ---------->8CO2(g) + 10 H2O(g)

We had to multiply by two because it is the integer that will give us the lowest coefficient. Multiplying through by 2 will give the expected result.

What is the overall equation for this chemical reaction?

ahrayia [7]

Answer:

Mg(s) + 2H⁺ → Mg²⁺(aq) + H₂.

Explanation:

To obtain the overall reaction, we sum the two half-reactions and omit the similar species in the reactants and products sides.

We have two reactions:

oxidation reaction:

Mg(s) → Mg²⁺(aq) + 2e.

Reduction reaction:

2H⁺ + 2e → H₂.

So, we add the two half-reactios and obtain the overall reaction:

Mg(s) + 2H⁺ → Mg²⁺(aq) + H₂.

Identify the type of interactions involved in each of the following processes taking place during the dissolution of sodium chlo

icang [17]

Answer:

A. Interactions between the ions of sodium chloride (solute-solute interactions).

B. Interactions involving dipole-dipole attractions (solvent-solvent interactions).

C. Interactions formed during hydration (solute-solvent interactions).

D. Interactions involving ion-ion attractions (solute-solute interactions).

E. Interactions associated with an exothermic process during the dissolution of sodium chloride (solute-solvent interactions).

F. Interactions between the water molecules (solvent-solvent interactions).

G. Interactions formed between the sodium ions and the oxygen atoms of water molecules (solute-solvent interactions).

Explanation:

The solution process takes place in three distinct steps:

Step 1 is the separation of solvent molecules.

Step 2 entails the separation of solute molecules.

These steps require energy input to break attractive intermolecular forces; therefore, they are endothermic.

Step 3 refers to the mixing of solvent and solute molecules. This process can be exothermic or endothermic.

If the solute-solvent attraction is stronger than the solvent-solvent attraction and solute-solute attraction, the solution process is favorable, or exothermic (ΔHsoln < 0). If the solute-solvent interaction is weaker than the solvent-solvent and solute-solute interactions, then the solution process is endothermic (ΔHsoln > 0).

In the dissolution of sodium chloride, this process is exothermic.
