Answer:
Explanation:
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)
The gases have no definite shape, low density, and are highly compressible while the liquids only have a definite volume but no definite shape.
<h3>What is a Matter?</h3>
Any substance which has mass and occupies space is called matter. Commonly, there are three states of matter that are:
- Solid - Solids have a rigid shape, definite volume, and high density.
- Liquid - Liquids have definite volume but no definite shape. They take the shape of the container in which they are placed.
- Gas - Gases have neither definite shape nor definite volume and have low density. They completely occupy the container in which they are placed.
There are other two states of matter that are Plasma and man-made Bose-Einstein condensates. They are not so common.
Plasma is commonly found in the universe. Stars are the superheated balls of the plasma.
Thus, gases have no definite shape, low density, and are highly compressible. On the other hand, the liquids only have a definite volume but no definite shape.

The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.
Produce a transmembrane proton electrochemical gradient as a result of the redox reactions. If protons flow back through the membrane, they enable mechanical work, such as rotating bacterial flagella.
