If we are talking about one single carbon atom, then 4 hydrogen atoms can be bonded to a carbon atom, because there is 4 electrons in the valence shell, and a valence shell needs 8 electrons in total, which causes the carbon to have 4 open bonds. A hydrogen has only one electron in its valence shell of 2, and needs one more to complete it. So, each hydrogen connects to 1 of 4 bonds on the carbon to complete the valence electron.
Fun fact, CH4 is methane.
These lines (there is four of them) are residuals of the fusion of the five sacrum vertebrae that are fused. These "vertebrae" or segments present a characteristics, being the first of them very similar to a lumbar vertebra, large, and the other vertebrae are<span> progressively smaller and flattened. They also present a curved shape being anteriorly concave.</span>
Carbon is very important because Trees take it (Co2) in in order for oxygen to be produced.
All plants for the most part take in Co2 so that they can produce oxygen,
and we need that oxygen to live , to pump blood into our lungs so we can roam around.
It is basically one of the main components of our every day life on Earth.
I really hope this helps you a lot.
Picture 1 depicts convergent boundary.
Picture 2 depicts divergent boundary.
Picture 3 depicts transform boundary.
<h3>What is a Divergent boundary?</h3>
This occurs when two tectonic plates move away from each other while convergent boundary occurs when the plates collide with each other.
Transform boundary is a fault along a plate boundary where the motion is mostly horizontal.
