The balanced chemical reaction:

K2SO4 + O2 = 2KO2 + SO2

Assuming that the reaction is complete, all of the potassium sulfate is consumed. We relate the substances using the chemical reaction. We calculate as follows:

7.20 g K2SO4 ( 1 mol / 174.26 g) ( 1 mol O2 / 1 mol K2SO4 ) ( 32 g / 1 mol ) = 1.32 g O2 consumed in the reaction.

Can this reaction take place/does it exist - . CaCl2+CO2+H20----> CaCO3 + 2HCl
mash [69]
Yes the reaction given above does exist
First of all CaCl2 will react with  water to form CaO  and HCl  then it will react with CO2 to form <span>CaCO3 
</span>CaCO3 + 2HCl <span>>>></span>     CaCl2+CO2+H20
so i conclude it does exist
hope it helps

If 100.0 grams of na3n decompose to form sodium and nitrogen, how many moles of sodium are formed? write and balance equation be
Yakvenalex [24]
The balanced equation is:
2Na_3N-\ \textgreater \ 6Na + N_2

Then proceed with the following equations.


100g Na_3N*(\frac{1molNa_3N}{82.98gNa_3N})*(\frac {6mol Na}{2molNa_3N})*(\frac {22.99gNa}{1molNa})=83.12gNa

The answer is 83.12gNa.
