The dissociation is:
CaCl2------------------Ca(2+) + 2 Cl-
(aq)
Water obtained from natural resources does not show neutral pH. What is the reason behind this?The neutral nature of water changes due to its ability to dissociate into H+ and OH- ions.The neutral nature of water changes due to mixing of various salts, bases, and acids, thus changing its pH.The neutral nature of water changes due to mixing of other neutral substances, thus changing its pH.
Hardest question ever
A compund
Unbalanced equation is calles skeletal equation. The difference between these equations is that the skeleton equation doesnot show the no. of atoms and molecules in the equation whereas the balanced chemical equation shows. Also the balanced chemical equation shows that the products and the reactants are solid, liquid, gas or aqueous.

H2o --> h+ + oh-
2H2 + O2 --> 2H2O
Evaporation is not a chemical reaction.
Ca(OH)2+HCL=CaCl2+H2o
You can represent a substance dissolved in water by adding the symbol "(aq)" next to it in a chemical equation. This symbol indicates that the substance is in aqueous solution. For example, NaCl(aq) represents sodium chloride dissolved in water.
Glucose + Oxygen = CO2 + Water (+energy) Energy is not a substance
Oxygen + Glucose > Water + Carbon Dioxide or iron + oxygen ---> Ironoxide
