The reaction that occurred when the antacid mixed with the HCl resulted in an additional product (besides a salt and water). Did you see evidence of this product? Describe the experimental evidence you witnessed that supports the formation of the additional product.

Explanation:

If an antacid has sodium hydrogen carbonate/Calcium carbonate, it reacts with HCl as shown

NaHCO₃+ HCl → NaCl + CO₂+ H₂O

Antacid acid salt gas water

CaCO₃+ 2HCl → CaCl₂+ CO₂+ H₂O

Antacid acid salt gas water

The formation of gas CO₂ is shown by brisk effervescence when the antacid (sodium hydrogen carbonate/calcium carbonate) reacts with HCl (acid). So CO₂ is the additional product formed and its formation is supported by observation of brisk effervescence as HCl is added to the antacid.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the answer is na (sodium)
