H2 is the formula for pure Hydrogen gas, whereas HCl is Hydrochloric Acid, which is a compound of Hydrogen and Chlorine.
Aside from the difference between American and British spelling and the singular and plural, sulfate ions have the formula SO4-2 and sulphite ions have the formula SO3-2. Chemically, then, the difference is one oxygen atom per ion.
a 10% solution of HCI's pH is 2
P(r/100)^2
if there is the same number of atoms on both sides e.g Mg + HcI-------------> Mg + HcI^2 (HcI squared) this is an unbalanced reaction because there is more chlorine on the right side than the left side. so when you balance the equation it will look like this: MG + HcI^2------------------>Mg +HcI^2
(Distance between the points)2 = (difference of the two x-values)2 + (difference of the two y-values)2
2
There is no difference, only your outcome. The formula for both is x+2
The polyatomic anions in sodium sulphate have the formula SO4-2, while the polyatomic anions in sodium thiosulphate have the formula S2O3-2.
HCI would contain two (2) covalent bonds, one between hydrogen and carbon, the other between iodine and carbon, leaving a lone pair on carbon. It is unlikely such a compound would last for very long that way, though.

Area=1/2 base x height is the formula for a triangle. Area = length x width is the formula for a square or rectangle.
caco3 and HCI its fizzes after the mixture is been add in our class we done the marble add with HCI and it fizzed it could give bubbles 2 eee bye1
