Complete the following statements to describe solids, liquids, and gases. select the correct answer from each drop-down menu.

a solid a definite volume a definite shape.

a a definite volume and definite shape.

a a definite volume a definite shape.

A solid has a definite volume and adefinite shape.  

A liquid has a definite volume and no definite shape.  

A gas has no definite volume and no definite shape.

Explanation:

Solids

Solids have a definite volume and definite shape

The particles present in a solid are very closely packed since the intermolecular forces between them are very strong. The molecules do not move apart.

Liquids

Liquids have a definite volume and no definite shape

The particles present in a liquid are closely packed since the intermolecularforces holds the molecules close together. The molecules slide over each other.  Liquids take up  the shape of the container

Gases

Gases have no definite volume and no definite shape

The particles present in a gas are very loosely packed since the intermolecular forces are very weak.  There are no attractive forces between the molecules.  Gases spread through the container

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

its mg hope this
