# 100kg fuel is known to consist of 8% CO2, 12% CO, 44% CH4, and 36% C8H16. The air used to burn this amount of fuel was supplied with 45% excess of the theoretical amount. Determine the complete composition of the combustion gases.​

Group 1 elements

Explanation:

Subtances that are included in the element are Iron (Fe)

Further explanation

A pure substance can be an element or compound.

The element is a single substance that cannot be broken down anymore or the simplest substance.

While the compound is a pure substance that is formed from a combination of two or more elements through chemical reactions and has a constant chemical ratio.

A mixture is a combination of two or more single substances. The properties of the mixture component are not lost / unchanged as in compounds.

The mixture can be divided into a homogeneous mixture if the composition / ratio of each substance in the mixture is the same and heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.

Mixtures can also be divided into solutions, suspensions, and colloids based mainly on the size of the particles

Homogeneous mixture = Solution

Heterogeneous mixture = suspension

The mixture is located between suspension and solution = Colloid

The solution is a mixture of two or more substances consisting of a solute and a solvent. The particle size of the solution is very small, less than 1 nm, it cannot be distinguished between the solute and its solvent medium. Substances in a solution cannot be separated through filtering.

The solution has the same composition in each of its parts.

Suspensions are rough mixes and are heterogeneous. Particle size is more than 100 nm.

The mixture is a murky solution, but it gradually separates due to the influence of gravity (undergoes precipitation). Suspension can be separated by filtering.

Colloids are mixtures of dispersed particles and dispersing particles. The size of colloidal particles lies between 1 nm - 100 nm

colloid mixtures cannot be separated through ordinary filtering, but rather with ultrafilters.

Let's look at the answer choices

A. Air

Included in the mixture because it consists of various elements and compounds such as H₂, N₂ and O₂. Air is a homogeneous mixture

B. Iron  (Fe)

Included in the elements in the periodic system lies in the transition group VIIIB (block d) in period 4 with atomic number 26 and atomic mass 56. Iron is included in the metal

C. Salt  (NaCl)

Included in the compound, because it is composed of Na and Cl elements to form NaCl compounds. This compound is included in a strong electrolyte which is fully ionized when dissolved in water so that it can conduct electricity

D. Sugar

Included in carbohydrate compounds and is an organic compound, which is composed of 3 main elements namely C, H and O

The detergent molecules can form bonds with both water and oil molecules. Therefore, although the oil and water aren't technically mixing with each other, the dish detergent molecules are acting as a bridge between oil and water molecules. As a result, the oil and water molecules aren't clearly separated in the bottle.
