Lewis structure of butane

This is the C4H10 Lewis structure: Butane. For Butane, we have a total of 26 valence electrons. Whenever we see the ending, "ane", we know that we're going to have Carbons and Hydrogens single bonded. That makes it a little bit easier to draw the C4H10 Lewis structure. We'll put four Carbons in a row and then we'll put Hydrogens around them. Because each Carbon needs to have four single bonds--each bond having two valence electrons, that'll give it an octet--we'll have three Hydrogens on the end Carbons and two on the center, like this. There are the three on the ends, and then we'll put two Hydrogens on the central Carbons. Next we'll place a single bond between each of the atoms to show that a pair of electrons is being shared.

So we've used all 26 valence electrons for the C4H10 Lewis structure, and we can see that each Carbon has four single bonds. Since each single bond has two valence electrons, that means that each Carbon has an octet. Each Hydrogen has a single bond, so it has two valence electrons. That means that it has a full outer shell as well. So we've used all the valence electrons that we had for C4H10 and everything has an octet..','.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
