Alka-seltzer is a solid mixture of two substances, sodium bicarbonate (nahco3) and citric acid (h3c6h5o7). the substances react to form water, carbon dioxide (co2), and na3c6h5o7.
list the reactants:

list the products:

write the balanced chemical equation.

1) List the reactants: sodium bicarbonate (NaHCO₃) and citric acid (H₃C₆H₅O₇).

Reactants undergo change during a chemical reaction.

2) List the products: water (H₂O), carbon dioxide (CO₂) and sodium citrate (Na₃C₆H₅O₇).

Products are the substances formed from chemical reactions.

3) The balanced chemical equation:

3NaHCO₃ + H₃C₆H₅O₇ → 3H₂O + 3CO₂ + Na₃C₆H₅O₇.

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
