Can someone help me with chemistry?

Complete reaction:

CaCO3(s) + 2 HCl(aq) -----> CaCl2(aq) + CO2(g) + H2O(l)

CaCO3(s) = Insoluble in water so no ions from it.

2HCL(aq) = aqueous so it is ionized to 2H+ and 2Cl-

CaCl2(aq) = aqueous so it is ionized to Ca2+ and 2Cl-

CO2(g) = Gas so ionization

H2O(l) = Liquid so no ionization (only aqueous compounds ionize).

So rewrite the reaction with everything split into their ions.

CaCO3(s) + 2(H+) + 2Cl(-) = 2Ca(2+) + 2Cl(-) + CO2(g) + H2O(l)

now cancel any ions that apear on both sides of the equation.

and the answer becomes:

CaCO3(s) + 2(H+) -----> 2Ca(2+) + CO2(g) + H2O(l)

I hope that makes sense. Good luck.

2HCl + CaCO3 ===> CO2 + CaCl2 + H2O

Its really kinda simple. CO2 is released as a gas, then calcium and chloride join due to ionic bonding (Ca^+2 and Cl^-1). to equal out the charges on chloride and calcium, it becomes CaCl2. then you have to add a 2 in front of HCl which leaves you with 2 hydrogens and 1 oxygen, they join to form water (H2O). Hope this helps!!!

The equation is

2HCl + CaCO3 ----> CaCl2 + H2O

Ionic equation is

2H+ + CaCO3(solid) -----> Ca2+ + CO2(gas) + H2O(liquid)

The Cl- ions stay unchanges in the reaction so they are ignored.

Molecular: CaCO3 + 2 HCl -----> CaCl2 + CO2 + H2O

Ionic: Ca++ + CO3-- + 2 H+ + 2 Cl- -----> Ca++ + 2Cl- + CO2 + H2O

Net ionic: CO3-- + 2 H+ -------> CO2 + H2O

2HCl + CaCO3 -> CaCl2 + H2CO3 //// overall equation

CaCl2 -> Ca(+2) + 2Cl(-) ////////////////// CaCl2 forms ions

H2CO3 -> H2O + CO2 ///////////////////// carbonic acid decomposes

///////////////////////////////// net ionic equation ///////////////////////////////////

2H(+) + 2Cl(-) + CaCO3 -> Ca(+2) + 2Cl(-) + H2O + CO2

A strong mineral acid reacts with a weak base to form a weak acid and a salt. The salt is CaCl2 and the weak acid is H2CO3. This acid can spontaneously decompose into CO2 and H2O. H2CO3 (carbonic acid) is what makes all the little bubbles in carbonated softdrinks and champaigne. Note that in all the equation the charge is balanced as well as the number of atoms.

BTW: this hapens around 2AM in my stomach when I grab the antacid tablets.

LOL he deserved an A but I am pretty sure that Hell is not freezing over......
