Lets Get Started

[F.Z.M. 7]

What are you even saying?

I said both forces cancel each other out = the immovable object wins. What in the hell have I even assumed?

Anyway, F.Z.M. 7, I didn't read both comments . Awesome's logic of friction is pretty much flawed - I am talking about you explaining to these guys about how it should work practically - and THEN they hopefully debunk it.

why should I? I have won a shawarama already
its you who wants to save himself

Exactly, but MarcoReus has made a very very stupid assumption. Thereby the force isn't unstoppable.

thts the first timw we agreed on sumthing.............

Shawarma invalid for a breach of contract.

Shawarma invalid for a breach of contract.

oh come on. Rondu na ban
what breach of contract?

come on I cleared everything up
what is left?

q 2
do we do it like this
15+15+30= 60
100 -------> 60
14 ---------> 60*14/100=8.4
15/8.4 =1.785
1.785/14= 0.1275
0.1275/5 = 0.0255 = 0.03 mol/dm3
or is there a better way??

q.1

A.

Boron has 3 valence electrons. Florine has 7 valence electrons. The option given presents a compound having 1 boron atom and 3 Florine atoms.

Florine will need 1 electron to complete its shell. It will share this electron with Boron. The rest is shown below.

Just consider the Boron Flouride structure. As you can see there are 8 electrons in the outer shell of Flourine. However, there are only 6 electrons in the outer shell of Boron.

how t o know which gas is most ideal and least ideal at room temperature and pressure

 

[F.Z.M. 7]

hydrogen is most I think.

 

[F.Z.M. 7]

so least must be radon

 

[asadalam]

hydrogen is most I think.

Really?We just started this chap,but our sir remarked on the side that Hydrogen never acts as an ideal gas?Or am i misinterpreting the question?

hehe....
vat chapter is tht from......we havent reached that yet....

 

[F.Z.M. 7]

No idea. I am talking from my General Knowledge
Ideal Gas is supposed to be the one that has a constant Pressure/Volume ratio, right?

 

[F.Z.M. 7]

google says most ideal is He

so ammonia is less ideal than carbon dioxide.....

-.- Fittay mun
Its from the states of matter,the ratio part is right but,H never behaves like an ideal gas,it deviates from the start,while some gases like ammonia are ideal at a specific temperature.No gas is ideal at all temps.
