Chemistry

Question 1

If there is suddenly an increase of protons in the blood, what would happened to the bicarbonate ions in the blood?

Answer 1

Bicarbonate ions would decrease since it would buffer the protons

Question 2

What is Faraday’s constant?

Answer 2

It is the charge of one mole of electrons (10^5 C/mol)

Question 3

What is the Lyman series?

Answer 3

A group of hydrogen emission lines corresponding to transitions from energy levels n≥2 to n=1

Question 4

What is the Balmer series?

Answer 4

A group of hydrogen emission lines corresponding to transitions from energy levels n≥3 to n=2 (includes four wavelengths in the visible region)

Question 5

What is the Paschen series?

Answer 5

A group of hydrogen emission lines corresponding to transitions from energy levels n≥4 to n=3

Question 6

How are Gibbs free energy and Keq related?

Answer 6

delta G = -RT ln(Keq)

Question 7

What are the periodic table trends?

Answer 7

As one goes left to right (across a period):
Atomic radius goes down
Ionization energy goes up
Electron affinity goes up
Electronegativity goes up

As one goes top to bottom (across a group):
Atomic radius goes up
Ionization energy goes down
Electron affinity goes down
Electronegativity goes down
