What does quantum number n tell us about the electrons of an atom?
the energy level
What does the quantum number l define, literally (definition), and practically (related to the way the atom looks)
It decides the energy "subshell" or shape and quality of orbitals.

A thermos is an example of a closed system.
A boiling pot of water is an example of an open system.
An unopened pop can is an example of an isolated system.
In a closed system, matter and energy are not exchanged with the surroundings.
F - isolated
T
F - closed
F - energy can be transferred.

What is the most efficient form of renewable energy
Nuclear
You have a solution of hydrochloric acid (HCl) with an unknown concentration. You titrate this solution with a 0.1 M sodium hydroxide (NaOH) solution. It takes 25 mL of the NaOH solution to neutralize 50 mL of the HCl solution.
Calculate the concentration of the hydrochloric acid solution.
0.050M

For arsenic which set of quantum numbers is valid?
n=4, l=1, ml=0, ms=1/2
n=3, l=2, ml=1, ms=-1/2
n=4, l=2, ml=-1, ms=1/2
n=4, l=0, ml=0, ms=-1/2
the first one
n=4, l=1, ml=0, ms=1/2
What is the cheapest form of renewable energy
Solar
I have two solutions of equal chemical compisition, which I have in an equal volume, they have the same exact temperature. Do they have the same exact heat?
yes.

What is "wet bulbing"
Humidity at its maximum, and high temperatures.
Define the pauli exclusion principle, and also hunds rule using FOUR orbital diagrams
Draw one that violates pauli's and follows hund's
One that violates hund's but follows pauli's
one that violates both.
and one that violates neither.
hint (you can do all of this using the 2S orbital at a minimum)

A sample of 1.00 g of benzoic acid (C₇H₆O₂) is burned in a bomb calorimeter. The calorimeter has a heat capacity of 4.50 kJ/°C. The temperature of the calorimeter rises from 25.00 °C to 28.00 °C during the combustion.
Calculate the heat of combustion (ΔHcomb) of benzoic acid in kJ/g.
-13.50 kJ/g
You have a 50 g sample of ice at -20 °C. How much energy is required to heat the ice to steam at 120 °C?
Given:
199.99kJ
Thats a lot of energy!
Whose 1939 nomination for the Nobel Peace Prize was retracted in February of that same year?
Adolf Hitler's
What is the correct set of quantum numbers for copper.
the third one, because the aufbau principle as we know it is wrong on this one, LOL!!!!!!!!!!!!!!!!
Which of these is the proper electron config of uranium?
You have a 150 g piece of metal at a temperature of 100.0 °C that is placed in a calorimeter containing 200 g of water at a temperature of 25.0 °C. The final temperature of the system is 30.0 °C.
Assuming no heat is lost to the surroundings, calculate the specific heat capacity of the metal.
~0.398J/g°C
