In the bonding of propane ([tex]C_{3}H_{8}[/tex]), there are 18 electrons involved.
You must count the electrons in propane's bonding using its Lewis structure. Propane ([tex]C_{3}H_{8}[/tex]) has three carbon and eight hydrogen atoms.
How to calculate bonding electrons:
Count the molecule's valence electrons.
Three carbon atoms supply 12 valence electrons since carbon possesses four.
Eight hydrogen atoms contribute 8 valence electrons.
20 valence electrons: 12 (carbon) + 8 (hydrogen).
Single-bond atoms to form the molecule's skeleton.
Propane's skeleton is H-C-C-C-H.
To complete atom octets, distribute leftover electrons.
Start by bonding each carbon atom to the surrounding hydrogen atom with two electrons.
Distribute the remaining electrons to satisfy the carbon and hydrogen octet rule.
Count bonding electrons.
Each bond has two electrons—one from each bonding atom. Propane has nine C-H bonds, therefore bonding electrons total: 18 electrons from 9 C-H bonds.

analyze animals to demonstrate evidence of the hereditary information that is passed from one generation to another. Welcome to Hamster Haven!
We are the world's largest pet store and research facility dedicated to studying hamster heredity.
Inside we have a team of geneticists who oversee the breeding and offspring of the hamsters to ensure that we have many varieties for our customers to choose from.
Recently, our team of geneticists has been studying how hamsters inherit fur length.
You are invited to join our team to assist in the process.
Let's take a look at our geneticist notebook to learn more about how traits are inherited.Let's take a closer look at cells. Inside of each cell is a nucleus. The nucleus is like the command center for the cell and houses all of the cell's genetic material, called chromosomes. Tightly wrapped in the chromosomes are individual proteins, called genes, on strands of DNA.raits are determined by the genes the hamsters inherit.
Each hamster can inherit the trait for long fur or the trait for short fur.Let's examine the hamsters that you will be investigating today.
Select each hamster to learn more about its dominant and recessive traits.

Explain how the process of weathering changes rock to eventually, over a long time, to become soil.
Answer:
Rocks turn into the soil through the process of weathering. Weathering is when rocks are broken down into smaller pieces. Over time a large rock is broken into smaller and smaller pieces, eventually turning into soil. Chemical weathering occurs when water gets inside of a rock and reacts with some of the mineral components of the rock, chemically changing them and weakening the rock's structure. This causes the rock as a whole to break down, and over time chemical weathering can break a rock into small enough pieces to become soil. Once the rock is in very tiny pieces, it mixes together with organic and other inorganic elements to form the soil we are familiar with.

Answer: Answer is below
Explanation:
Is there a connection between a star's size and a star magnitude?The brighter the star, the smaller the magnitude. So, no. There was no connection between the size and magnitude.
Name a different property other than the ones in the chart that can also be used to classify stars.Temperature, mass, color, luminosity, and size.
The magnitude of a star decreases with its brightness. So, no. The size & magnitude had nothing to do with one another.
What is star?All of us are reasonably familiar with stars. On the majority of clear nights, we can see them as minuscule, glittering specks of light throughout the sky. Numerous poems, stories, or nursery rhymes have been written about stars.
The star is supported against gravity by nuclear fusion events in its core, which also yield photons, heat, and trace amounts of metallic elements. The Sun comes the star that is closest to Earth. The magnitude of a star decreases with its brightness. So, no. The size & magnitude had nothing to do with one another. mass, colour, luminosity, size, and temperature. In addition to the ones that are in the chart, these are separate properties.
Therefore, the magnitude of a star decreases with its brightness. So, no. The size & magnitude had nothing to do with one another.
