CaO(aq) + 2HCl(aq) -> CaCl2(aq) + H2O(l)
An ionic bonded and dissociated compound, calcium oxide, reaction with a fully dissociated strong acid, hydrochloric acid that produces a dissociated salt, calcium chloride and water.
whats the balanced chemical equation
There are several things that may symbolize a chemical reaction. One of the main symbols is a chemical equation which will represent the entities in the reaction. .
it is as i think a physical change
Yes
sulfur sodium chloride sand is a homogeneous mixture (solution)
whats the balanced chemical equation
C6H12O6 + 6 O2 = 6 CO2 + 6 H2OThis is the correctly balanced equation for the combustion of Fructose. Physical states depend on how its being combusted so I left them off.

Ca(OH)2 + 2HNO3 -> Ca(NO3)2 + 2H2O
Sodium chloride is a chemical compound (NaCl), not a property.
In the same way as you made sure that the chemical elements balanced on both sides of a chemical reaction equation, so also the physical dimensions balance.
The dissolution of sodium chloride is considered as a physical process.
That would probably be something like a "physical equation".That would probably be something like a "physical equation".That would probably be something like a "physical equation".That would probably be something like a "physical equation".
Sodium chloride is NaCl, calcium chloride is CaCl2. Consequently all the physical and chemical properties are different.
The physical appearance of Sodium chloride is a white crystalline solid.
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Sublimation is a physical change.
