Answer:freckles with straight hair
Explanation:
Answer: Option (B) is the correct answer.
Explanation:
A covalent compound is a compound formed by sharing of electrons. And, in a covalent network solid atoms are bonded by covalent bonds in a continuous network that is extending throughout the material or solid.
This continuous arrangement of atoms are like a lattice.
For example, diamond is a covalent network solid in which carbon atoms are arranged in a continuous lattice like structure.
Hence, we can conclude that the statement all the atoms are covalently bonded to other atoms to form a lattice-like structure, best describes the structure of covalent network solids.
There are three ways that scientists have proved that these sub-atomic particles exist. They are direct observation, indirect observation or inferred presence and predictions from theory or conjecture. Scientists in the 1800's were able to infer a lot about the sub-atomic world from chemistry.
The phase development of the eutectic reaction includes the equilibrium point of Liquid, crystals of A, and crystals of B
<h3>What is the Eutectic Reaction?</h3>
This refers to the three-phase reaction that occurs when a liquid forms after cooling.
Hence, we can see that the hypo eutectic reaction occurs when there is a homogenous mixture of substances that undergoes a reaction where it melts and solidifies.
The hyper eutectic reaction has to do with the metallic alloy that contains a composition that has exceeded its eutectic point.
