Is someone able to share a picture or pdf of this question in test 2?

Lucy Agnew 3E

This can be further explained why you can do this equation in pages 457-458 of the textbook! IT shows you how it works

Lucy Agnew 3E

Was that list in the textbook? For strong acids?

Lucy Agnew 3E

less dissociation => less H30+ produced=> higher pH!

Lucy Agnew 3E

Intramolecular forces are harder to break! You are actually breaking a BOND rather than a force of attraction

Lucy Agnew 3E

Also, usually you can tell if it is a bigger molecule and only dissociates partly e.g. CH3COOH, it will be a weaker base

Lucy Agnew 3E

I think for this question it is best to just memorize the different shapes and whether it has one lone pair or two lone pairs etc.

Lucy Agnew 3E

Another good tip
Single bond : sigma bond
Double bond: sigma and pi bond
Triple bond : sigma and two pi bonds

All of these answers are very helpful! Intermolecular interactions is a hard topic to grasp so these were very helpful!

Lucy Agnew 3E

All of these are so helpful! I didn't even think to distinguish the qualitative model from the quantitative model!

I was wondering if for resonance structures do you need to have the same element of atom surrounding the central atom? And can there be more than one double bond for resonance to occur? In all the examples we have looked at and some I have looked at online, there seems to be only one double bond in...

I was wondering does polarity always have to do with the symmetry of the molecule or are there exceptions? I think symmetry plays a role in guessing whether the molecule is polar or not, but you also have to consider the electronegativities of the atom as this is really important. There are probabl...

All these answers were really helpful thank you!!

I will try my best! Induced dipole means that when atoms of an element that are bonded together e.g F-F , because there will always be partial positive and partial negative charges going on within the element, one atom with partial charges can induce the atoms bonded around it to have partial charge...

Lucy Agnew 3E

Bond angles are caused by the laws of electron repulsion theory, and atoms that interact around a central atom they are all bonded to orientate themselves to produce the most stable structure

Lucy Agnew 3E

I didn't understand this concept at all so thanks for explaining it to me better!

Lucy Agnew 3E

The trends are also useful to predict/determine where an element would be in the periodic table!

Lucy Agnew 3E

I always forget this so thank you for the explanation!

Lucy Agnew 3E

I leave all the numbers not rounded until the end! That way it’s the most accurate answer!

Lucy Agnew 3E

Did Lavelle say he was starting bonding today in class? And if so does anyone know how in depth we will go with the bonding?

Lucy Agnew 3E

These explanations were very helpful! Totally forgot about this !

Lucy Agnew 3E

Very helpful thank you! I got stuck on this problem too!

Lucy Agnew 3E

Does anyone have a good definition for the photoelectric effect? Thanks!

Lucy Agnew 3E

Has anyone got a way to remember formulas? Or will we get all the formulas we need on the exam

Lucy Agnew 3E

This is going to be so helpful! The more resources the better!

Lucy Agnew 3E

Can anyone explain how Lavelle cancelled both the s and s^-2 to result in the only unit being m left over? If that makes sense haha!

Lucy Agnew 3E

I know that we got all of the equations in the most recent test, but do we get all the equations and formulas in the midterms and finals? And to save time, does anyone have a fast way to remember them?

Thanks!

Lucy Agnew 3E

@AlbertDuong Thank you for that explanation! Completely forgot how to do it and so that was very helpful

Lucy Agnew 3E

I used dm^3 alot when I was doing A level chemistry; is what we use for dm^3 just the same as 1000cm^3? I was just confused as it hadn't come up yet

Lucy Agnew 3E

Thank you so much for this! Very in-depth explanations of what we need to do to succeed!
