A molecule's shape greatly influences the polarity of the compound, the molecular structure has an impact on molecular characteristics. The shape of a molecule affect the molecule's function. Therefore, option B is correct.
What is molecule ?Based on the environment, the term may or may not include ions that meet this requirement. A molecule is a collection of two or more atoms held together by the attractive forces known as chemical bonds.
Molecule shape play a key role in anticipating how one molecule may interact with another, as well as in determining macroscopic features like melting and boiling points.
Polar substances have higher boiling and melting temperatures, tend to dissolve in other polar compounds, and can either form solids or liquids.
Thus, option B is correct.

In your own words, explain why each of the filler blocks (s,p,d,f) on the periodic chart have their characteristic width(number) of groups.
Answers
Answer:
Each of the four blocks of the periodic table is the collection of elements that have common valence orbitals, or that their valence are found in one of the four orbitals with azimuthal quantum number 0, 1, 2, or 3 which corresponds to the shape (s), principal (p), diffuse (d), or fundamental (f) orbitals respectively
The maximum number of electrons in the s-orbital = 2 electrons
The maximum number of electrons in the p-orbital = 6 electrons
The maximum number of electrons in the d-block = 10 electrons
The maximum number of electrons in the f-orbital = 14 electrons
Therefore, given that the elements of the within each of the blocks have their valence electron in the corresponding orbital in which they are located on the periodic table, given the periodic nature of the periodic table, the width of each block of elements corresponds to the maximum number of elements that can be found in their valence orbital.
Therefore, we have;
The width of the s-block elements = 2 block units
The width of the p-block elements = 6 block units
The width of the d-block elements = 10 block units
The width of the f-block elements = 14 block units

If 45.0 mL of a 4.00 M sodium sulfate (Na2SO4) solution is used for the reaction shown above, how many moles of sodium ions were present in solution before the reaction proceeded?
Answers
Answer:0.360
Explanation:
I had this on ck12 yesterday
The moles of sodium ions were present in the solution before the reaction proceeded is 0.36moles
Molarity of a solutionThe formula for calculating the molarity of a solution is expressed as:
Molarity = moles/volume
Given the following parameters
Molarity = 4.00M
Volume of sodium sulfate = 45mL = 0.045L
Substitute to have;
Molarity = 4 * 0,045
Molarity = 0.18
Since there are 2 atoms of sodium ion in the solution, hence the moles of sodium ions were present in the solution before the reaction proceeded is 0.36moles

The answer is 1:2 option B
Plz mark as brainliest............. hope it helps
The ratio of the metal cationic atom to the nonmetal anionic atom will be 1 :2. Therefore, option B is correct.
What is the lewis electron dot diagram?A lewis electron dot representation is utilized to represent the number of bonds, the bonding atoms, and the lone pairs on the atoms in the molecule or chemical compound.
Straight lines are used to represent the bond between atoms that are bonded to one another and excess electrons are represented as dot pairs to show the lone pairs on the atoms.
In the given image, calcium has two valence electrons and Fluorine needs one electron to complete its octet. So the calcium will donate its two electrons to two F. Each Flourine will accept one electron Therefore, the compound formed will be CaF₂.
Therefore, the ratio of the calcium cationic atom to the Fluorine anionic atom will be 1 : 2.
