Polar molecules
มุมมอง 5432 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains that when a molecule has polar bonds, it may or may not lead to that molecule being polar. Examples include adding vectors to determine whether or not a molecule has an overall dipole.
Calculating empirical formula and molecular formula from percentage composition data
มุมมอง 2792 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains the difference between the empirical and molecular formula for a compound. Worked examples show how to calculate the empirical formula for a compound using its percentage composition by mass. Examples include using the molar mass to determine the molecular formula.
Electronegativity and polar bonds
มุมมอง 1902 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains the concept of electronegativity and how it affects the polarity of covalent bonds. The difference in electronegativity can be used to predict the bond type.
Nuclear magnetic resonance spectroscopy (nmr) in organic chemistry
มุมมอง 1892 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how to use carbon-13 nmr and hydrogen-1 or proton nmr to determine the structure of the hydrocarbon part of an organic molecule. Examples include chemical shift, integration and spin-spin coupling.
More Molecular Geometry
มุมมอง 1262 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how to use the Valence Shell Electron Pair Repulsion theory (VSEPR Theory) to predict the shapes of molecules in which the central atom does not have an octet. Mrs V also explains how some atoms can expand the octet.
Molecular shapes and the VSEPR Theory
มุมมอง 2422 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how to use the Valence Shell Electron Pair Repulsion Theory to determine the shapes of molecules in which the central atom has an octet. Bond angles are explained in terms of the extra repulsion from a lone pair of electrons.
The effect of catalysts on the rate of reaction
มุมมอง 4212 ปีที่แล้ว
I this chemistry tutorial, Mrs V explains how catalysts are able to speed up a chemical reaction. Surface catalysts, acid-base catalysts and enzymes are discussed.
Infrared Spectroscopy in Organic Chemistry
มุมมอง 1692 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how to identify some common functional groups in organic chemistry using infrared spectroscopy. Using infrared spectra to distinguish alcohols, carboxylic acids and esters are discussed.
The effect of surface area of solid reactants on reaction rate
มุมมอง 1.3K2 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how dividing a solid reactant into smaller pieces can increase the rate of a chemical reaction.
The effect of gas pressure on reaction rate
มุมมอง 1.2K2 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains the effect on reaction rate of increasing the pressure of a gas by reducing the volume. We also consider the effect of increasing as pressure by adding an inert gas.
Mass Spectrometry in Organic Chemistry
มุมมอง 7102 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how to use mass spectrometry to provide clues about the structure of an organic molecule. Full worked examples include the use of the molecular ion peak to determine molar mass and fragmentation to determine the position of functional groups.
Atomic Absorption Spectroscopy
มุมมอง 2812 ปีที่แล้ว
In this chemistry tutorial, Mrs V explains how atomic absorption spectroscopy is use to determine the concentration of metal ions. Full examples are shown for constructing calibration curves and for undiluted samples and diluted samples.
The effect of temperature of reactants on the rate of reaction
มุมมอง 4532 ปีที่แล้ว
In this chemistry tutorial, Mrs V uses collision theory to explain how increasing the temperature of the reactants increases the rate of a chemical reaction. The effect of light intensity on the rate of photochemical reactions is also discussed.
The effect of concentration of reactants on reaction rate
มุมมอง 9682 ปีที่แล้ว
In this chemistry tutorial, Mrs V uses the collision theory to explain how increasing the concentration of reactants increases the rate of a chemical reaction.

awesome video
❤
that aluminium oxide and zin oxide are ampphotericoxides. just wanted to say
E
HEY
WOW😮😮🎉
YaYa that good, I would like to have it or download for more studying
Thanks madam❤🎉
Thanks it helped a lot❤❤
great videos as alway mrs v!
Love this video
My dream is to become a chemist! This is awesome!!
Thanks mate
🎉

Plz share ur e mail for sharing some knowledge
Hi
Great content. Thanks a lot.
Thanks for the clear message
White smoke- coolant/ water in the combustion chamber Black smoke- a rich environment in the combustion chamber or incomplete combustion Blue smoke- engine burning oil.
:3
I miss you mrs v where have you gone
i will see it in my recomendations lol
Thanks
fascinating
I am a chemistry teacher in Korea. It was a chemical reaction that was not found in the Korean curriculum, so I enjoyed it. Thank you! ^^ I know everything, but it is always interesting to see that copper oxide changes color as it turns into copper sulfate.
Permisi saya mau tanya.. Lebih besar konduktivitas tembaga atau tembaga oksida?
Who came to this for homework/online studying 👇
What next video??? You haven't even uploaded a single video for 2 years
Thanks for video. I was just wondering How can we define Fe+2 and Fe+3 percentages ? It has 99% Fe2+ means 1% Fe3+ ?
yeesh
The mass of HCl in the M1 concentration was a bit confusing as the balance was (-19.4g) before you put the beaker with the acid in
Impressive

Thanks for the vid Mrs v 🔥🔥
Well done
Im surprised a teacher would hav students watch this video when there are so many other in-depth videos out there, no offence
Abosolutley excellent demonstration! You were clear and concise, I was really able to follow and under the concept. Thank you!
crazy glaze 💀
Excelent decuction. Thanks a lot.
Thanks! Using this for my chem test practical!
welp .

Very instructive❤
Wow you are the best chemistry teacher
not in a class this is just interesting
Thank you
THANK YOU SOOOOOO MUCH, really really appreciative
i love this
Wow! Outstandning!
Thank you Soo much🤍
