Front

What is the pH of a 0.50 M solution of a strong acid (HX)?

Back

0.30

Front

What is the correct way to draw the Lewis Dot Structure for Carbon?

Back

No, dots are in the wrong places.

Front

What is the formal charge on the oxygen atom in a Lewis dot structure if it has 6 valence electrons and 7 electrons represented?

Back

-1

Front

How many total valence electrons are in CO2?

Back

16

Front

What type of bonding is present in SF6?

Back

Covalent/molecular

Front

Define a strong acid.

Back

A strong acid is an acid that completely dissociates in solution, releasing all of its hydrogen ions.

Front

Define a weak acid.

Back

A weak acid is an acid that partially dissociates in solution, releasing some of its hydrogen ions.

Front

What is the formula to calculate pH?

Back

pH = -log[H+], where [H+] is the concentration of hydrogen ions.

Front

What is the significance of formal charge in Lewis structures?

Back

Formal charge helps determine the most stable structure by indicating the distribution of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell.
