## What happens when sulfur dioxide reacts with water and oxygen?

In the formation of acid rain, sulfur dioxide reacts with oxygen and water in the air to form sulfuric acid.

## What will the be the result of mixing sulfur dioxide and oxygen in a reaction chamber?

Problem: Sulfur dioxide, SO2(g), can react with oxygen to produce sulfur trioxide, SO3(g), by the following reaction 2SO2(g) + O2(g) → 2SO3(g) The standard enthalpies of formation for SO2(g) and SO3(g) are ΔH°f [SO2(g)] = -296.8 kJ/mol ΔH°f [SO3(g)] = -395.7 kJ/mol Calculate the amount of energy in the form of heat (kJ …

What happens when sulphur reacts with oxygen Class 8?

Sulphur reacts with oxygen to give sulphur dioxide. Which is an acidic oxide.

### When sulfur dioxide is added to oxygen sulfur trioxide is produced?

When sulfur dioxide is added to oxygen, sulfur trioxide is produced. Sulfur dioxide and oxygen, SO2+O2, are reactants and sulfur trioxide, SO3, is the product.

### What is the heat of reaction when sulfur dioxide reacts with oxygen to form sulfur trioxide?

First is the combination of solid sulfur with oxygen gas to produce sulfur dioxide gas. This produces 297 kJ of heat per mole of sulfur. The next step is the combination of sulfur dioxide gas with oxygen gas to produce sulfur trioxide gas. This reaction produces 98 kJ of heat per mole of sulfur dioxide gas reacting.

When sulphur reacts with oxygen which gas is produced?

sulphur dioxide
Sulphur burns in oxygen to form sulphur dioxide.

## What happens when sulphur burns in oxygen?

Sulphur when burnt in air forms SO2. Sulphur reacts with oxygen as it burns in the presence of oxygen, producing Sulphur dioxide, which is acidic in nature.

## What does hydrogen sulfur and oxygen make?

Looking at the formula we can tell two things about sulfuric acid. – It is formed from three different elements, namely, sulfur(S), oxygen(O) and hydrogen(H). – Each unit of sulfuric acid consists of one atom of sulfur, four atoms of oxygen and two atoms of hydrogen. Its formula is Al2(SO4)3.

Why is SO2 and not SO3 formed when sulfur is heated in air?

Since they are formed by the interaction between sulphur and O2 molecules, these compounds are called sulphur oxides. The key contrast between SO2 and SO3 is that SO2 has two atoms of oxygen bonded to a sulphur atom, whereas SO3 has three atoms of oxygen bonded to a sulphur atom.

### What does Hess’s law make it possible for you to do?

Hess’s law allows us to calculate ΔH values for reactions that are difficult to carry out directly by adding together the known ΔH values for individual steps that give the overall reaction, even though the overall reaction may not actually occur via those steps.

### What is the enthalpy change of reaction of SO2 O2?

The enthalpy change of reaction is -197.7 kJ.

What happens when sulphur reacts with oxygen give chemical equation?

Sulfur reacts with oxygen to form sulfur dioxide. Sulfur can also combine with oxygen to produce sulfur trioxide. 2S(s)+3O2(g)→2SO3(g) Transition metals are capable of adopting multiple positive charges within their ionic compounds.
