Answer: -
D. Network
Explanation: -
Diamond is an allotrope of carbon. In diamond each carbon atom makes four bonds to other carbon atoms.
They exist in tetrahedral shape.
Diamond has strong covalent bonds. They extend in all the three dimensions
Such covalent bonds are called network covalent bonds. They require significant amounts of energy to break.
Answer:
The answer is the respiratory system
Explanation:
The function of the respiratory system is to move two gases. These two gases are called oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them.
Answer:
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
Explanation:
Answer:
The answer is
<h2>19.31 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of gold = 475.09g
volume = 24.6 cm³
The density of the gold is

We have the final answer as
<h3>19.31 g/cm³</h3>
