Compounds retain most of the properties of their constituent elements. The correct answer is FALSE
vekshin13 years ago
3 0

Answer:

The correct answer is False.

Explanation:

Compounds do not retain the properties of their constituent elements. This is because the elements that form the new compounds have different bonds between them, and the intermolecular forces produce that change the physical and chemical properties of these new compounds. The state of aggregation at ambient temperature (melting and boiling points), electrical conductivity, hardness and solubility in polar and non-polar solvents depend on the strength of the chemical bond involved between the elements.

Have a nice day!

Liquids and solids are referred to as "condensed phases" because the attractive forces cause molecules to become stationary. lea
Savatey [412]

Answer:

leave little space between the molecules.

Explanation:

Matter is made up of small particles called molecules. These molecules present in matter are arranged inside its bulk.

In liquids and solids, the molecules are arranged very close together in such a way that there is only a little space between them. This is why liquids and solids are referred to as "condensed phases".

They are quite unlike gases where there is a lot of space between gas molecules.

What is the mass of oxygen in 3.34 g of potassium permanganate?
3241004551 [841]

Answer:

1.35 g

Explanation:

Data Given:

mass of Potassium Permagnate (KMnO₄) = 3.34 g

Mass of Oxygen: ?

Solution:

First find the percentage composition of Oxygen in Potassium Permagnate (KMnO₄)

So,

Molar Mass of KMnO₄ = 39 + 55 + 4(16)

Molar Mass of KMnO₄ = 158 g/mol

Calculate the mole percent composition of  Oxygen in Potassium Permagnate (KMnO₄).

Mass contributed by Oxygen (O) = 4 (16) = 64 g

Since the percentage of compound is 100

So,

                        Percent of Oxygen (O) = 64 / 158 x 100

                        Percent of Oxygen (O) = 40.5 %

It means that for ever gram of Potassium Permagnate (KMnO₄) there is 0.405 g of Oxygen (O) is present.

So,

for the 3.34 grams of Potassium Permagnate (KMnO₄) the mass of Oxygen will be

                  mass of Oxygen (O) = 0.405 x 3.34 g

                  mass of Oxygen (O) = 1.35 g
