What is the state of matter in a combustion reaction?

Combustion reactions must have oxygen as a reactant. Note that the water produced is in the gas state, rather than the liquid state, because of the high temperatures that accompany a combustion reaction.

Is water a liquid or gas in a combustion reaction?

If combustion is rapid and hot as in vigorously ionizing reactions like fire, water is released as a gas. If combustion is slower, as inside the human body, water is released as a liquid.

What is the rule for combustion reactions?

A combustion reaction always has oxygen as one reactant. The second reactant is always a hydrocarbon, which is a compound made up of carbon and hydrogen. A combustion reaction also always produces CO2 and H2O.

What does a fuel react with in a combustion reaction?

In a combustion reaction, a fuel is heated and it reacts with oxygen. The fire triangle summarises the three things needed for combustion – a fuel, heat and oxygen. If one of these things is removed from a fire, the fire goes out. When fuels burn in combustion reactions, they release useful thermal energy (heat).

How do you determine state of matter?

Another way that we can describe the properties of matter is the state (also called phase). The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including a gas, liquid, or solid state.

What is an example of a combustion reaction?

Combustion reactions occur when oxygen reacts with another substance and gives off heat and light. Burning coal, methane gas, and sparklers are all common examples of combustion reactions. Essentially, any reaction that involves burning something is a combustion reaction.

How does combustion create water?

Water is formed in combustion by oxidation of hydrogen in hydrocarbon fuels, and thereby adds water to the hydrologic cycle and atmospheric water stores.

Where do combustion reactions occur?

A combustion reaction occurs when a substance reacts quickly with oxygen (O2). For example, in the Figure below, charcoal is combining with oxygen. Combustion is commonly called burning, and the substance that burns is usually referred to as fuel.
