Chemistry P1 and P2 today

[robinhoodmustafa]

I wrote one direction.

U mean the electrons wala Mcq. even I wrote electrons move in one direction.

 

[asma tareen]

I wrote one direction.

Calcium Silicate (Slag) liquid

i wrote that too but in federal book the answer is iron

 

[Shadow]

Obviously. I wrote the same.

iron is also correct, ryt?

 

[iamLbert]

1 i guess two doesnt really fit...

thanks for ur info.... minus one or two... mampus gue salah...

 

[robinhoodmustafa]

Not in solid nor in liquid state.

Safe

U mean the electrons wala Mcq. even I wrote electrons move in one direction.

But, again, I didn't read the question and wrote this because I though they were asking for the movement of electrons when conducting current.

 

[Saad Mughal]

iron is also correct, ryt?

Iron doesn't form an Alkali.

 

[iamLbert]

isn't that electrons moved both directions? If one direction, I'm wrong again... -1 again...

U mean the electrons wala Mcq. even I wrote electrons move in one direction.

IRON IN SOLID STATE was one of the options which is incorrect.
Iron and Slag are in molten state at the bottom of the furnace.

Nope!

iron was also their but the State was Solid but Iron is always in molten form when extracted in the blast furnace so We were left with Slag because It is in Liquid state

yea but if u look at the question carefully it said iron in SOLID form whereas its supposed to be in LIQUID form in blast furnace

it wx calcium silicate ryt????

In a circuit electron moves toward positive terminal and positive charges move toward negative side.. Because electron cant move in both opposite direction is that negative charges would repel it from coming toward it

Lithium and Calcium was the answer


what was the answer of "Takes 4 complete shell in a Configuration"

 

[Shadow]

I thi
I think we had to choose a par of compounds.

I chose aluminium oxide and carbon dioxide.

i cannot remember, which ques is this one? :/

 

[ritx]

I think the electrons would move in two directions because the heating element in the kettle is a metal, and in metals wlectrons flow randomly in all directions. They werent talking about the flow electric current, that would have been in one direction.

 

[robinhoodmustafa]

it wx calcium silicate ryt????

yes

copper i think.... i checked in the periodic table

 

[danial 234]

calcium
