How does one balance this equation?

Question

CaCo3 + HCL => CaCl + Co2 + H2O

Answer 1

One must be careful when writing chemical formulas and chemical reactions….
CaPItalizaTioN does matter (capitalization does matter).

CaCo3 does not mean the same thing as CaCO3.
HCL does not mean the same thing as HCl.
Co2 is not the same as CO2.

The proper way to write out the chemical reaction that you were trying to say is:
CaCO3 + HCl --> CaCl2 + CO2 + H2O
Although the change is subtle, it does matter.
Also, notice that I corrected the subscript on the Calcium Chloride from CaCl to CaCl2, this is because the Ca+2 ion needs two Chloride (Cl-) ions in order to balance its charge and make an overall neutral compound.

Balancing this chemical reaction, one will get,
CaCO3 + 2 HCl --> CaCl2 + CO2 + H2O
We only needed to add a coefficient of 2 in front of the Hydrochloric acid in order to balance the reaction so that the same number of atoms of each type of element appear on both sides of the reaction.

Answer 2

Put these numbers before each compound, respectively:
2, 2, 2, 3, 1
There is nothing to account for the oxygen. If it is a combustion, then the answer changes. A combusion would have O2 (oxygen is a diatom) and the answer would be as so (with O2 leading):
1, 4, 4, 4, 6, 2

Answer 3

At a wager: TiO2 + 2C + 2Cl2 --> TiCl4 + 2CO C is a sturdy, Cl2 a gasoline (i think of) and CO is definately a gasoline. No clue approximately the different 2. Why no longer seem it up? you would be able to desire to have records tables or some thing.
