Answer:
8 electrons
Explanation:
As per the <u>octet rule</u>, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.
Physical because it can easily turn back into the original "substance"
Answer:The molecules in a raw egg absorb the heat energy, they use this energy to change shape
Such a chemical reaction is said to be endergonic, which means 'energy in'.
Egg molecules will never undergo these reactions without the input of energy (usually in the form of heat)
I hope this helps, if not, let me know :)
Answer:
The molarity of a sugar solution is 2 M.
Explanation:
Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:
4 L of solution--------8 moles of sugar
1 L of solution ------x= (1 L of solution x 8 moles of sugar)/4 L of solution
x=2 moles of sugar---> <em>The solution is 2M</em>
Area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus, or office building.
The advantages of local area network are:
• you can share resources
•you can share your software applications
• you can have easy and cheap communication
• you have centralized data
• you have data security
•you have Internet sharing
The disadvantages is a local area network are:
• high set up cost
• local area network administrators can see and check personal data files of each and every user
• Data security threats
• maintenance jobs
• covers limited areas
