Explanation:
Molar mass of Hg = 200.59g/mol.
Therefore Moles = Mass / Molar mass
= 100g / (200.59g/mol) = 0.499mol.
Because i think melting is kinda the biproduct of evaporation.
Answer: IONIC EQUATION.
Explanation:
A chemical equation is defined as the form by which a chemical reaction is represented mathematically. These are written in the form of symbols and chemical formulas of reactants and products which are taking part in the chemical reaction. A chemical equation can be written in two forms, these include:
--> MOLECULAR EQUATION: in this type of equations, the compounds are written and represented in a molecular form. This is sometimes referred to as a balanced equation.
--> IONIC EQUATION: This is a type of chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. A typical illustrated example is seen in the reaction between AgNO3(aq) and NaCl(aq) :
Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) → AgCl(s) + Na+(aq) + NO3-(aq)
The (aq) written in the above equation signifies they are in aqueous solution.
