The pH of water [H2O] is generally 7, and hence neutral. If the pH of a body of water is above or below the previously established value of 7, it could mean a large number of things, generally outside the realms of the empircal formula, i.e. a foreign substance.
When an acid reacts with a base, the products formed are water and a salt. The hydrogen ion (H+) from the acid combines with the hydroxide ion (OH-) from the base to form water (H2O), while the remaining ions combine to form a salt.
Yes.Additional answerThere's often some air in water, but not always. It has to dissolve to get there. It's not there automatically
dihydrogen monoxide
H2O is a scientific version for Water, it is on the periodic table :) x
H2O is the chemical formula for water, which is a common compound found on Earth in liquid, solid, and gaseous forms.
Considering "Bonding - H2O" is the only way to Special Summon "Water Dragon" and there are few ways to search for the Spell card, it would be best to include three copies of "Bonding - H2O"; two at the very least.
10S + 40 HNO3 → 10 H2SO4 + 40 NO2 + H2OS + 6HNO3 → H2SO4 + 6NO2 + 2H2OS + 4HNO3 -→ SO2 + 4NO2 + 2H2O
Nothing. NaCl creates a reverse reaction to H2O.
it turns into a gas
CaCO3 + 2H2O ==> Ca(OH)2 + CO2 + H2O
The water goes from the liquid state to the gas state. H2O(l) -> H2O(g)
It combines with H2O molecules.
turns back into h2o
Condensation happens when a gas or a vapor changes into a liquid or a solid. H2O (v) ----->H2O (l or s) V= vapor L=liquid S=solid
No, H2O is just normal water, H2O2 (hydrogen peroxide) is a very toxic, reactive, oxidative, bleaching chemical.
It will oxidize, which causes it to turn green.
CaO+2hcl----->CaCl2+H2O
