A combustion reaction is a reaction that reacts in the presence of oxygen molecules. Methane will release -3115 kJ/mol of heat.

<h3>What is a combustion reaction?</h3>

A combustion reaction includes the reaction between the chemical reactant and oxygen molecule to produce the product. The combustion reaction between methane and oxygen is given as:

CH₄(g) + 2O₂ (g) → CO₂(g) + 2H₂O (l), ΔH = -890 kJ/mol

The stoichiometry coefficient from the reaction gives 1 mole of methane releases -890 kJ/mol enthalpy.

So, 3.5 moles methane will release = 3.5 × -890 = -3115 kJ/mol

Therefore, -3115 kJ/mol of heat is released.

How does high pressure effect the solubility of a gas?
Damm [24]

Answer:

Gases as might be expected, increase in solubility with an increase in pressure. Henry's Law states that: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution. ... When the bottle is opened, the pressure above the solution decreases.

Give the product expected when the following alcohol reacts with pyridinium chlorochromate (PCC). (Assume that PCC is present in
Hoochie [10]

Answer:

Kindly check the explanation section.

Explanation:

Based on the description of the reacting -OH group containing Compound, the drawing of the chemical compound is given in the attached picture.

So, without mincing words let's dive straight into the solution to the question.

The reaction between the OH containing compound and PCC is an oxidation reaction.

Looking at the carbon number 1 which the first OH group and CH3 are attached to. Oxidation can not occur here as tertiary alcohol can not be oxidize.

Hence, the second OH will be oxidized into a carbonyl group, C = O. Kindly note that when alcohol oxidizes it turns into an aldehyde.

The equation for the reaction is also given the the attached picture.
