Why do you need to think about polarity of the different ingredients in your salad dressing in order for it to turn out well?

No.

Explanation:

Hello,

In this case, a salad dressing makes up of an oil-and-vinegar heterogeneous mixture as long as if it is let to stand it is possible to decant its constituents by density difference, therefore, we do not mind about the polarity of the different ingredients. The only necessity is a well shaking before its use.

Best regards.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
