Question

I already 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.

Answer 1

Answer:

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
