D. Common characteristics
The ignition occurs when a mixture of fuel & oxygen encounter an external heat source with sufficient heat<u> Piloted ignition.</u>
<h3>
What is Piloted ignition?</h3>
When a volatile fuel is close to a nearby local energy source (pilot) and reaches its lower limit of flammability in air, piloted ignition may be possible. The flame that originates in the premixed system spreads outward from the pilot. The first law of thermodynamics for systems with fixed mass only describes the energetics of this process.
<h3>Definition of thermodynamics </h3>
The science of thermodynamics examines how heat, work, temperature, and energy are related. The general topic of thermodynamics is the transfer of energy from one location or form to another. The fundamental idea is that heat is a type of energy that is equivalent to a specific quantity of mechanical labor.

Explanation:
<u>a) 2,2,4-trimetilhexano</u>
En esta molecula tenemos una cadena lineal de seis carbonos. En los carbonos 1,2 y 4 tenemos grupos metilos.
<u>b) 3,6-dietil-2-metiloctano</u>
Para esta molecula tenemos una cadena lineal de 8 carbonos. En el carbono dos tenemos un grupo metilo y en los carbonos tres y seis tenemos dos grupos etilo.
<u>C) 3,5-dietil-2,8-dimetil-6-propilnonano</u>
Finalmente, para esta molecula tenemos una cadena de nueve carbonos. En los carbonos dos y ocho tenemos 2 grupos metil, en los carbonos tres y cinco tenemos 2 grupos etilo y en el carbono seis tenemos un grupo propilo.

Answer: ENERGY: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics.
MATTER: When one organism eats another, the matter, or carbon, nitrogen, and other essential elements, are transferred from one to the other. These elements move from the producers, to the consumers, and eventually to the decomposers, cycling the matter through the ecosystem.
