Mg+2HCl-->H2+MgCl2 you would it have to make it so each is equal on each side you would add a 2 on left in front of HCl because on the other side there is already 2 H and 2Cl so just put a 2 in front of HCl

Four acids are analyzed and there KA values are determined which of the following values represents the strongest acid
Advocard [28]

x= the coefficients in front of the substance in the balanced chemical equation  

[H+]= the concentration of hydrogen ions  

[A-]= the concentration of the other ion that broke off from the H+  

[HA]= the un-disassociated acid concentration  

The higher the Ka value, the greater amount of disassociation of the reactants into products. As for acids, they will break down to form H+ ions. The more the H+ ions, the stronger acidity of the solution. Thus since A has the highest Ka value, that represents the strongest acid.  

You can determine the Ka value from a number of ways. If equilibrium concentrations are given of a certain acid solution, you can find the proportion of the concentration of ions to the concentration of the remaining HA molecules, using the equation above. Also, pH and KpH can be used in a number of ways. This gets more complicated and depends on the situation, and requires more advanced equations.


Hope this helped a little, its obviously not my best work

Pyridoxine contains 11 hydrogen atoms, 8 carbon atoms, 3 oxygen atoms, and 1 nitrogen atom. The chemical formula would be C8H11NO3. A chemical formula of a substance tells the number of atoms of the elements that is involved in the compound. Pyrodoxine is commonly known as vitamin B6. It is mostly found in food like meat, whole grains, nuts and avocados. Also, it is can be present in dietary supplements. It has a number of important functions in the body. Dietary supplements are manufactured to prevent vitamin B6 deficiency. Also, it is used in treating a specific type of anemia or the lack of red blood cells.
