What are some facts about covalent bonding?I need some information for my chemistry poster please, thank you.

Answers

Answer 1

Answer: When two atoms come near each other, sometimes they stick together to make a molecule. One way they can stick together is by covalent bonding.In covalent bonding, the atoms are unstable because their outer rings of electrons aren't filled up. By sharing electrons with other atoms, these atoms can fill up their outer rings and become stable. In water, for instance, the oxygen atom needs two more electrons to be stable, and the hydrogenatoms each need one. When they get together, the oxygen atom shares oneelectron with each of the hydrogen atoms, and the hydrogen atoms eachshare one electron with the oxygen atom.Now that the atoms have become stable, it's pretty hard to knockthem back into being unstable again, so covalent bonds are strong andmolecules that form with covalent (sharing) bonds are strong molecules.Covalent bonding makes very strong connections between the atoms,so it's hard to break these molecules apart. On the other hand,molecules that join with covalent bonds aren't very much attracted toeach other (unlike with ionic bonding), so they move freely around eachother. That means that most molecules that form covalent bonds makeeither liquids or gases, like water and carbon dioxide. The main exception is metals,which hold together using covalent bonding but are still solids. That'swhy metals are so flexible and easy to melt so you can make them intodifferent shapes.

After data are collected, they are often arranged in a(n) ___________???

Answers

Data are often arranged in some sort of table or spreadsheet. This allows the researcher(s) to be able to run statistical models on the data as a way of finding and understanding trends that may occur. This table also gives a form of proof for those looking to replicate the findings.

How would you measure the pH of a coloured substance such as red ink.why?

Answers

There are 3 possible ways of determining pH.
1. A pH meter, 2. Litmus paper/ pH test strips or 3. Titrations.

1. A pH meter works by sending a small electric current through the solution. An electrical current can only be created if there are free-moving particles such as H+ ions from an acid or OH- ions from a base. The pH meter can determine the pH by how high the conductivity is.

2. Litmus Paper or pH test strips are strips that turn a specific colour under a specific pH. This colour can then be compared to a colour chart which will tell you the pH. The downfall of this method is that the red ink will stain the strip and you will be unable to get an accurate reading.

3. A titration is the best method, if done properly, for determining pH.
