Ayala is making salad dressing. she mixes oil and vinegar in a blender until a smooth consistency is formed. explain whether this is a heterogeneous or a homogeneous mixture and why.

The mixture formed will be heterogeneous mixture.

Explanation: When we mix oil and vinegar and blend it together to form a smooth mixture, the final mixture will still be heterogeneous in nature.

As we know that vinegar is a solution of acetic acid in water, which is polar in nature and oil is non-polar in nature.

When, we mix polar compound with a non-polar one, the resulting mixture may mix for a certain time, but after a time, we will be able to see the two layers in a mixture.

And heterogeneous mixtures are defined as the mixtures in which there is a distinct physical boundary present between the solutions in a mixture.

Hence, the mixture of oil and vinegar is a heterogeneous mixture.

"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."

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
