Ialready dismantled each formula and got that the equation caco3 + 2hcl -> cacl2 + h20 is flawed just need the reasoning as to why it is flawed. the choices are shown below in the picture. will give brainiest and 20 points.

Part 1

option C

CaCO3 + 2HCL -> CaCl2 + H20

Part 2

option A - The model is missing a product, CO2

Explanation:

In part 1, the ONLY FLAWED reaction model is CaCO3 + 2HCL -> CaCl2 + H20, simply because the model is missing a product, CO2.

Now, the CORRECT reaction model is stated as follows:

CaCO3 + 2HCL -> CaCl2 + H20 + CO2

Note that the reaction model DESCRIBES the how the useful Calcium Chloride (CaCl2) is formed from limestone (CaCO3), alongside water H2O and Carbon dioxide (CO2).

So, option C is the RIGHT ANSWER for Part A; while option A is to Part B

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
