Alka-seltzer® is an antacid. one of its active ingredients is nahco3. write out an equation to show how alka-seltzer® neutralizes stomach acids (hcl).

NaHCO3 + HCl --> NaCl + CO2 + H2O

Explanation:

NaHCO3 which is an acidic salt because of the replaceable H+ (Bronste lowry acid), by definition acid dissociates in water to release a proton.

NaHCO3 dissociates in water to give Na+, H3O+ and HCO3-

Stomach acid which is HCl also dissociates in water to give H3O+ and Cl-

The H3O+ and HCO3- combines briefly to form a weak carbonic acid almost immediately, which then further dissociates to form H2O and CO2. CO2 is burped out from the mouth.

Na+ and Cl- combines to form NaCl in water which is a table salt solution.

Below is an attachment containing the step by step reactions

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
