12 H2O is a chemical formula representing 12 molecules of water.
There are 4.17 moles of H2O present in 75.0g of H2O.
H2O(l) --> H2O(g) + heatshows the process of freezing.
In the reaction, HBr donates a proton (H+) to H2O, making HBr the acid and H2O the base. The resulting products are Br- (conjugate base of HBr) and H3O+ (conjugate acid of H2O).
To make CaCl2 and H2O, simply mix calcium chloride (CaCl2) with water (H2O). The calcium chloride will dissolve in the water, forming a solution of CaCl2 and H2O. The chemical equation for this process is: CaCl2 + H2O → CaCl2 · H2O.
The chemical equation for Na2S (sodium sulfide) reacting with H2O (water) is: Na2S + H2O → 2NaOH + H2S
