How is acid deposition formed?

How do strong and weak acids differ in the extent of ionisation?

Isabella Barkett 1G

How do you find whether a pair of species are an acid-base pair?

Isabella Barkett 1G

Do we need to know the giant structure examples of covalent and ionic bonding (ie. graphite and diamond)?

Isabella Barkett 1G

What are the differences in the melting and boiling points of ionic and covalent bonds?

Isabella Barkett 1G

Are covalent bonds usually soluble or insoluble in water?

Isabella Barkett 1G

How does calcium obey the octet rule when reacting to form compounds?

Isabella Barkett 1G

Is the compound drawn as Cl-O-O or O-Cl-O?

Isabella Barkett 1G

What is the resonance structure of benzene (the aromatic ring compound)?

Isabella Barkett 1G

What is the difference between the continuous spectrum and the line spectrum?

Isabella Barkett 1G

How does ionisation energy change down and across the periodic table?

Isabella Barkett 1G

Will we need to know the shapes of the different orbitals? ie how p is a dumbbell shape or s is spherically shaped?

Isabella Barkett 1G

I think the questions will be similar to those we did in class discussions.

Isabella Barkett 1G

The orbitals are differentiated in terms of their relative energy, s having the lowest and f having the highest (s<p<d<f).

I think there are two anomalous configurations when an element fills the orbital 'abnormal': chromium and copper which do not seem to fit the pattern. Chromium is energetically more stable to have 3d5 then pair up the 4s orbital ((Ar)4s1 3d5). Copper has extra stability due to a full set of 3d orbit...

Electrons have a mass but in comparison to protons and neutrons in an atom, they will not affect the total mass I think.

The Rydberg Equation is used to find the wavelengths of all the spectral lines in the emission spectrum of hydrogen, for example the wavelength of light which moves between n=2 and n=4.

Isabella Barkett 1G

We looked at the Hydrogen spectral series which accounts for the transition of electrons between different energy levels in an atom. The hydrogen spectrum consists of a series of lines of different colours (violet, blue, green and red) in the visible region of the spectrum. The Lyman series correspo...

The most common form of measurement is Celsius, Kelvin is almost used in relation with celsius as it is an absolute scale meaning that it indicates the temperature at which molecules stop moving (0K = absolute zero).

I find it easier to break the problem in multiple steps as it reduces any room for error and makes it easier to understand the question.

Volume is the amount of space a substance takes up. On the other hand, the density is the mass of an object divided by the object's volume.

Isabella Barkett 1G

Also if it helps, g/mol = mass (in grams) / number of moles (mol) - lending itself to the correct units of the molar mass

Isabella Barkett 1G

Usually with chem practicing a variety of questions on the topic is very useful - so I would recommend doing extra questions in the text book.

Isabella Barkett 1G

Also it is easier to use whole numbers as it would be simpler to decipher the mole ratio between reactants and products.
