That pH only lies between 1 and 14

List them. I'll start it off off:

We are told the 3rd electron shell can hold up to 8 electrons.


Ah you took the first one that came to my head :redface:

My school has never taught it - I just took it and study it myself. :smile:

My teacher told our class all the electron shells hold up to 8.

I started laughing.
Sin, cos and tan are the only trig functions :colonhash:
There are three states of matter
A 555 timer is the most advanced IC you will need to learn about.

Well, it's only used for the first 20 elements, for which that is true in realistic molecules/conditions.




Precisely.

Homosexuals are just like everyone else...

Wow. Here we see a close-minded ********
GCSEs dont teach that, life teaches that. I have loads of homosexual friends, they are no different to normal people, they just fall in love with people of the same gender

This annoys me also. I vent a sigh when teachers say light is a wave. :colondollar:


please tell me what light is? to be fair, the wave model is really useful for optics. Really really useful.

On a technical point that's actually true though they come joint with every other fundamental particle as a zero-dimensional object.

Air resistance does not exist...


It only sometimes exists at degree level and when I say sometimes I really mean rarely...

Light can also behave like particles.

It's a little more complicated than that... actually a lot more...

Really? Doesn't that cause issues if something travels a predicted 120m instead of, say, an actual 119.8m?

University is like school with just better friends. :smile:

You can't square root a negative.
Bob wasn't a real person and he didn't have 4 apples :frown:
Current flows from positive to negative.

The gravitational field strength of earth is 10 (just call it 9.81, or do you think I'm too dumb to deal with decimals :colonhash:)
GCSEs will shape your future
pH can't go below 1 or above 14.

explain the pH thing pls

Obviously, but this isn't a thread to discuss wave-particle duality. Lol :smile:

\text{pH} = - \log _{10} \left[ H^+ \right] So technically, it can go below 0 and above 14. I think battery acid is a common example of a negative pH acid.Posted from TSR Mobile

that's a problem for engineers, and the air resistance terms actually depend on the object, the speed of the object and literally the weather... and it doesn't help that fluid dynamics is not yet complete either...
