hey vinny is gettin rough thanx 2 municipality  but still dunt understand do ve use CO2 in rusting n ya one more can u explain this question below realli dont get it

B, right?

NO!! he said it was a mistake.. CO2 isnt used in rusting. Only o2 and water and iron. Thats rusting

As for ur question, notice that the four are bonded to each other, so its P4. If it was 2 bonded to each other and another two bonded then its 2P2. the number before shows the number of molecules while the number after shows how many atoms stuck together

B, right?

Ya as i explained

I dont know why the f** i sai it .. sorry .. ;\ .. its like im studying french n chemi bot side by side ..

Listen to Baladya as he says .. u;ll get an A*

neutralisation reaction is with acid and base right? can it be with hydrocloric acid and sodium carbonate and why when it is carbonate not base

No.!! Only Acid + Base. Other Acid reactions like Carbonates do produce salts but they are not neutralisation reactions...
Right Vin?

hey but in de ms is written P4 NOT 4P

[Baladya]

thats what i said...

Answer is P₄ shows a molecule of Phosphorous

cuz i found it and ms says it is neutralisation

[Baladya]

cuz i found it and ms says it is neutralisation

dunno :S maybe m wrong, check with VIN

It is a neutralisation reaction..

Acid + Carbonate ------> Salt + Water + Carbon dioxide

OK guys im signing off .. its almost 4am here !! .. BEST OF LUCK !! DO WELL

Hey when we add excess zinc to acid (to make salt)

Why is it excess? I understand but i dunno what to write... should i write to have a complete reaction, or to obtain as much salt as posibble?
