That is only the combustion of a hydrocarbon. Rust is a combustion reaction because oxygen is added.

Fe(s) + O2(g) => FeO2(s)

<u>Answer:</u> Because some of the processes are also known as incomplete combustion.

<u>Explanation:</u>

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.  The chemical equation for this reaction follows:

\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O

If supply of oxygen gas is limited, it is known as incomplete combustion and carbon monoxide gas is also produced as a product. The chemical equation for this reaction follows:

\text{hydrocarbon}+O_2\text{(limited)}\rightarrow CO+CO_2+H_2O

Thus, we cannot say that all the combustion reactions produce carbon dioxide and water as products because it depends on the supply of oxygen gas.

Which is the smallest particle into which water (H2O) in a glass can be broken down and still remain water? A. a water molecule
Gnesinka [82]

Answer:-

A. A water molecule

Explanation:-

A molecule is the smallest particle of a compound that retains all it's chemical properties.

Here H2O is a compound. So the smallest particle that will retain all the chemical properties and still remain water is water molecule.

Atoms Hydrogen and Oxygen both have different chemical properties from water H2O and are thus different.

Hydrogen peroxide is different molecule from water. So it is also not water.

From the calculations, the heat that is required is 2.1 kJ.

<h3>What is the specific heat capacity?</h3>

The term specific heat capacity has to do with the amount of heat that must be supplied to 1Kg of a substance in order to raise its temperature by 1K.

In this case;

H = mcdT

H = 100 grams  * 4.18 J/gC * (25 - 20)

H = 2.1 kJ
