Because one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
2 Li + 2 H2O ------> 2 LiOH + H2
It is called a Formula. An example is H2O: 2 atoms of hydrogen and 1 atom of oxygen.
CaO + H2O--> Ca(OH)2
there are 3 atoms in a h20 molecule 2 parts hydrogen - (h2) 1 part oxygen - (O)
Equation SO2 + H2O ----> H2SO3 (Sulfurous acid) Having water as vapour does not change the formula in anyway so keep it simple
This is not an equation at all. An example of a correct (and balanced) equation would be: 2H2 + O2 --> 2 H2O
Example: methane burning CH4 + 2 O2 → CO2 + 2 H2O
No, H2O is covalent.
An example is:2 KOH + H2SO4 = K2SO4 + 2 H2O

Water?
H2O is an example of a mixture. It can be broken back down to its original parts 2 parts of Hydrogen, and 1 part of Oxygen.
h2o is an example of a polar molecule because when you look at the molecule it is not symmetrical. therefore it is polar.
H2o
no
H2o
liquid or water
