yes
2 H2 + O2 = 2 H2O
An example is:2 KOH + H2SO4 = K2SO4 + 2 H2O
two hydrogen and oxygen H2O (small 2)
Ca(OH)2 + CO2 = CaCO3 + H2O
The chemical equation is:C2H5OH + O2 = 2 CO2 + 3 H2O
H2O (small 2!) - 2 hydrogen atoms bonded to one oxygen atom.
yes ur supposed 2 do everything it tells u to do to it
To write the elemental definition of water (H20) in HTML, use the <sub></sub> element to surround the 2. SUB designates a particular portion of text as subscript. So... <p>H<sub>2</sub>O</p> Will give results similar to: H2O
how do you write a balanced chemical formula for this question CaO + H2O ---> Ca(OH)2
its H2O and its because water is made up of 2 Hydrogen atoms and 1 Oxygen atom. H= Hydrogen O= Oxygen
The balanced chemical equation for the reaction C2H6 + O2 → CO2 + H2O is: 2 C2H6 + 7 O2 → 4 CO2 + 6 H2O
2 hydrogen molecules 1 oxygen molecule H2O
