Question

In the reaction, HCl (aq) + NaHCO3 (aq) – NaCl (aq) + H20 (1) + CO2 (g), which of the
reactants or products is a gas?

NaHCO3

NaCl

H2O

CO2

1 Answer

  • CO2 is the gas. The letter subscripts following the reactants and the products are what indicates the state of matter. (s) is solid, (l), it is a lowercase l, is liquid, (g) is gaseous state, and (aq) stands for aqueous solution, which is a solution in which the solvent is water. Hope this helps.
