Answer:
22.5 mL
Explanation:
We are given an amount of a fluid in a graduated cylinder and required to determine its volume.
Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.
The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
Atomic radius is the distance from the nucleus to the last valance electron up to which the effect nucleus can be felt. The size of the atom depends on the Electrostatic interaction between nucleus and electron. Number of atomic orbitals present. With the increase in numbers of orbitals down the group the size of the atom increases. Again, as the numbers of electrons increases in the period ,the electrostatic interaction between nucleus and electron increases along the period. Therefore, size of atoms decreases along the period.
As expected the element with highest atomic radius is the last element of group 1 , Which is FRANCIUM ( Fr)
In ionic bond Im pretty sure this is the correct answer. I know its been 4 days since you post this but thought I could still answer your question. it all starts when Cation and Anion bond together creating ionic bonding.
Answer:
<em>The answer to your question is </em><em>True</em>
Explanation:
CH2O is a polar molecule. It has three polar bonds that are arranged asymmetrically, thus allowing their dipole moments to add up and give the molecule an overall dipole moment. CH2O has a central carbon atom that forms two single bonds with the two hydrogen atoms and a double bond with the oxygen atom.
