The electrons in a water molecule are attracted more strongly to an oxygen atom’s nucleus.

What is another name for a homogeneous mixture?

A solution is another name for a homogeneous mixture.

What is the result of the unequal distribution of electrons in a water molecule?

The unequal distribution of electrons results in oppositely charged regions.

How do buffers affect pH?

Buffers are mixtures that can react with acids or bases to keep the pH within a certain range.

How does a heterogeneous mixture differ from a homogeneous mixture?

In a heterogeneous mixture, the parts remain distinct—that is, you can identify the individual parts.
