Explanation:
The orbital for fluorine is 1s 2s 2p. All of the boxes should be filled COMPLETELY until you can't no more. How do you know if you can't anymore? By the <u>atomic number</u> of the element. The atomic number for fluorine is 9. So, you keep adding arrows starting from the first box all the way to the last until you have reached the atomic number, in this case, 9.
Answer:
You should use a graduated cylinder or a beaker
Answer:
To predict the number of shearing electron between the two atoms (ionic bond) the concept of electronegativity is used.In the other words the ability of atoms to attracts the electron is known as electronegativity of the atom.
If the electronegativity between two atoms is greater than 1.7 then these types of bond is known as ionic bond.These types of bond will show ionic character.
For the answer to the question above,
The re<span>action of solid iron with aqueous copper sulfate is an example of a single displacement type of reaction which exchanges only the cations of the element and the compound. In this case, the equation is
Fe (s) + CuSO4 (aq) = FeSO4 + Cu (s) </span>
Answer:
Explanation:
First, lets find the molar mass of CO². This is approximately 12 + 2(16) = 44 g/mol. Now, let's set up the conversions.
This is Avogadro's number
↓
243.6g CO² * (1 mol CO² /44g CO²) * (6.023 * 10^23 molecules/ 1 mol)
When we cancel out the units, we are left with 3.33 * 10^23 molecules of carbon dioxide. I hope this makes sense!
