Which is the correct lewis structure for acetylene (c2h2)?

Each carbon atom has 4 valence electrons, and each hydrogen atom has 2 valence electrons. In the Lewis structure for acetylene, the three lines between the carbon atoms represent three bonds between the carbon atoms. Since each line represents 2 shared electrons, the carbon atoms share 8 electrons. The two hydrogen atoms share two electrons with each carbon atom.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
