Carbonic acid's chemical formula is H2CO3. Its decomposition to water (H2O) and carbon dioxide (CO2) is represented by the equation:
H2CO3(g) → H2O(l) + CO2(g)
Answer:
Ok so, as a society we are addicted to our technology. We have technology from our yeah Our hands to our bathrooms. Pretty soon we will have more technology than people can handle. I mean we live by technology (Siri,Alexa,GOOGLE, etc.) there are even robots that are made to look and act like us! We are pretty advanced!
Answer:
57.3mL of 0.250M KMnO4 are required
Explanation:
3.225g of oxalic acid are:
3.225g×(1mol / 90.03g) = <em>0.03582mol of oxalic acid</em>
Based on the reaction, 5 moles of oxalic acid react with 2 moles of KMnO4, thus, for a complete reaction of oxalic acid you need:
0.03582mol of oxalic acid × (2mol KMnO4 / 5mol Oxalic Acid) = <em>0.01433mol of KMnO4</em>
<em />
If concentration of KMnO4 is 0.250M, liters in 0.01433mol are:
0.01433mol × (1L /0.250mol) = 0.0573L ≡<em> 57.3mL of 0.250M KMnO4 are required</em>
<em></em>
I hope it helps!
