i want to know why hcl is more powerful than carbponoc acid since we know the one which has more hydrogen inos is the one which has more power full

It is not important wich one has more hidrogen.First of all,you should know that H2CO3(carbonic acid)is the mineral water that you drink,the soda in the coke,and that's why it is not powerfull.Than,I studied in highschool a very interesting method to make the difference between acids:you take the periodical system of the elements and see them.Now,you should know that the electropozitivity grows in the period from left to right( for ex.Li Is less electropozitive than Be or B),and it increeses in the groupe from "above" to "below"(Li is less electr.poz. than K).But! The electronegativity is the opposite:is decreeses in the period from left to right,and in the group it decreeses from :above to below.This is the way you compare the elements and make the difference.So,HCL is more powerfull than H2CO3 because Cl is more electronegative than C.I hope I could help you.It is a safe method.
Let me also give you the reactivity series:so the power of the acids grow this way:HF HCL HBr HI
Than those with O2: H2CO3 H2S H3PO4 HNO3 HCL H2SO4 HCLO4 You can see how powerfull HCL and sulfuric acid are!

You are incorrect when you say the one with more hydrogen ions is more powerful. The strength of an acid (or base) depends on how well it dissociates or ionizes in water. HCl dissociates 100% and is therefore called a strong acid. Carbonic acid dissociates less than 100% and is a very weak acid. It also has a great tendency to decompose into carbon dioxide and water.

It's not a matter of which has more hydrogen but of the readiness of the compound to ionise into positive (hydrogen) and negative ions.
This depends on the strength of the negative ion, that is, the strength of its tendency to acquire extra electrons from the hydrogen. Chlorine has a much greater affinity for an extra electron than does the carbonate (CO3) group, so it "grabs" the hydrogen electron more readily. This makes HCl a stronger acid than H2CO3.

not necessarily. an acid is powerful when it undergoes complete dissociation. in many case, such as vinegar, which has many hydrogens, it partially ionises, and this makes it a weak acid. HCl is stronger because the Cl is very electronegative, thus pulling the hydrogen's electron cloud. when this happens the hydrogen is easily ionised when mixed with water. carbon is weakly electronegative, and although there is oxygen as well in carbonic acid, which is quite electronegative, the oxygen would be pulling carbon's electron cloud.

that's lots much less a query of covalency than of bond means. Carbonic acid is particularly benign stuff; the Coca-Cola business enterprise corporation has been coming up wealth from it for a century. yet eating hydrochloric acid supply you a foul day: in assessment to carbonic acid, that's in basic terms mildly ionized, hydrochloric acid is fullly ionized, and all of those ions are working around finding for some element to react with.

HCl more readily to ionized compare to carbonic acid.

HCl. Its not how many hydrogen, but Ionic Hydrogen. If it is just plain hydrogen, fat would be more acidic.
