<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Water is a molecule which is formed by the combination of hydrogen and oxygen atoms. The chemical formula for this is 
Ionization is a special type of dissociation process. It is defined as the process in which a molecules splits into its ions.
When water dissociates, it leads to the formation of 2 ions, which are hydroxide ion and hydrogen ion.
The chemical equation for ionization or dissociation of water molecule is:
Hence, the correct answer is Option C.
Answer:
Increasing precision with multiple measurements
Explanation:
The more measurements you take (provided there is no problem with the clock!), the better your estimate will be. Taking multiple measurements also allows you to better estimate the uncertainty in your measurements by checking how reproducible the measurements are.

Descriptive, Comparative, and experimental.
The mass of water is calculated as follows
find the moles of each reagent
that is moles = mass/molar mass
for H2s = 84.7/ 34= 2.485 moles
O2 = 78.4 / 32 = 2.45 moles
since 2 moles of H2S react with 3 moles of O2 therefore 2.45 moles of oxygen will be used up therefore O2 is the limiting reagent and H2S is in excess
2H2S + 3O2 ----->2So2 + 2H2O
by use of mole ratio between O2 and H20 which is 3:2 the moles of H2O is therefore = 2.45 x2/3= 1.63 moles of H2O
mass of H2O = moles x molar mass
= 1.63 g x 18g/mol = 29.4 g
