Answer:
The answer is 
21.5 L
 .
So, start with the balanced chemical equation for the decomposition of hydrochloric acid
2
HCl
→
H
2
+
Cl
2
 
Notice that you have a 
2:1
 mole ratio between 
HCl
 and 
Cl
2
 , which means that every 2 moles of the former will produce 1 mole of the latter. The number of moles of 
HCl
 you have is.

I don't know if that is but I try my best just correct me if I'm wrong thank you!!
 
        
             
        
        
        
Qualitative chemical and enzyme tests helped Avery identify DNA as the transforming principle by conducting <span>a series of tests to find out if the transforming principle was DNA or a protein and the result is that </span>no protein was present but that DNA was present. Hope this answers your question.
        
                    
             
        
        
        
Assuming conditions are at 25c and 1 bar 101.25 Kpa 1 mole of gas is equal to 22.4 L 
So if you have 500L of ar gas the you have : 500L / 22.4 × 1 Mole = 22.3 moles of ar after accounting for sig figs..Hope that helps
        
             
        
        
        
Answer:
Keep it simple. If all the oxygen contained in the 200 grams of potassium chlorate is produced in the decomposition, then all we have to do is find out how many grams of oxygen are there in the 200 grams. This we can do by calculating the ratio of oxygen mass to the whole. Using 39.1 for potassium, 35.45 for chlorine and 3 times 16, or 48 for the oxygen, we get a total of 122.55 grams per mole for potassium chlorate, of which 48 grams are oxygen. This ratio is 48/122.55. This ratio times the original 200 grams of the compound, gives us 78.34 grams of oxygen produced.
