<span>B. When two molecules collide with enough force, old chemical bonds are broken and new bonds form, resulting in one or more new substances</span>
Hello there! I'm gladly to help you out! :)
Melting Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water.
Hope this helped!
Answer:
Element Y, or the third option
Explanation:
Alkanes are insoluble in water, but soluble in ether. Their boiling points are pretty low, barely reaching 200 degrees, so element Y is an alkane.
One can tell by looking at the titration curve of an acid and base whether the acid used is a strong acid or a weak acid. For a titration of a strong acid and a strong base, the pH at the equivalence point will be neutral, that is, pH 7. If the titration involves a weak acid and a strong base, the pH at the equivalence point will not be neutral, the solution will be basic at the equivalence point.
