HELP! Grade 10 Chemistry...
-----------------------------------
What do you get with :

PtCl4 + Cl2 --> ? PtCl4 + Cl2

from what i see you get no reaction at all.
-----------------------------------------------
is this reaction correct? 

carbonic acid + sodium bicarbonate -- > carbon dioxide + water + sodium carbonate (washing soda)
    H2CO3      +      NaHCO3            -- >        CO2         +  H2O  +      NaCO
    H2CO3      +     2NaHCO3            -- >        CO2         +  2H2O  +      Na2CO

The top one is not a cemical reaction, and I believe the bottom one is correct, haven't done it in a semester, but I destroyed Science this year.

Thx a lot,
More questions...
--------------------
How is sodium bicarbonate sythesized? 
I thought its a base so i followed the text book method of oxidation and dissolve in water
2Na + O2 -> 2NaO
NaO + H2O -> 2Na(OH)
As you can see, I get sodium hydroxide which is not what i want...wtf...
--------------------
How do you sythesize  potassium sulfite? K2SO3
If you do the same thing as above you get potassium hydroxide (soap). 
--------------------
The text book listed the above 2 i guess irregular bases but did not explain how they are produced.
I find this to be the highest order of disorderliness.

Actually, I do, but I rather not dig my notes out to do someone else work, and give them answers. They need to learn.

that's why you tell them the process, not the answer ;)

its not hwk.. im studying for a test tmr, i asked here because i couldnt find the answer after i tried solving it from what i learned
a problem with anonymous questioning is that u dont know what to trust, u could assume im lying but i would say im not....

Na(CO_3)_2 == Sodium Bicarbonate

Where is the carbon in your synthesis reactions?
