Answer:

C) They all have single covalent bonds.

Explanation:

The given hydrocarbons Butane,Ethane,Methane,Propane belongs to alkane group.

In alkane group consists of hydrogen and carbon in which carbon_carbon bonds are single and carbon_hydrogen bond is also single.

The elements of this group makes bond by sharing of electrons that means they form single covalent bond.

Butane have 4 , Ethane has 2, Methane has 1, and Propane has 3 carbon atoms.

Since they have different number of carbon atoms so their structural formula also differs.

What state of matter has a definite shape and volume.
anastassius [24]

Solids have a definite shape and volume. They are always the same shape no matter what they are contained in; their volume is also the same because they don't change unless you add or take away from it.

____________________________________________________________

Liquids have an indefinite shape but definite volume. They expand to fill out the space they are contained in, but their volume doesn't change unless you take out or add more of the liquid.

Gases have an indefinite shape and volume. Gases expand to fill out the space they are in and also don't have a clear shape because they are not always in one form.

Chlorine is a halogen and has 7 valence electrons, which is represented by crosses on the left
makkiz [27]

There are 2 electrons in the overlapping region.

Chlorine is the second member of the halogen group which are form of family of elements that resemble one another very closely.

The electronic configuration of chlorine shows the arrangement of chlorine electrons within it's atom.

At the outer most shell of the atom is seven electrons, therefore requires only one electron each to attain the octet arrangement.

The overlapping of the orbitals indicates the chemical bond formed by sharing of electrons between atoms called covalent bonding.

To complete it's outer most shell, it will need to share electron with another chlorine atom.

Therefore, there are 2 electrons in the overlapping region.
