# A student has a sample of the strong acid \(\text{HNO}_3\text{(aq)}\) represented in the particulate diagram. The four answer choices represent different samples of \(\text{Ba(OH)}_2\text{(aq)}\) using the same particulate scale. Assume that both solutes dissociate completely, water molecules are omitted, and the neutralization reaction goes to completion. Which particulate representation contains an amount of \(\text{Ba(OH)}_2\text{(aq)}\) that is stoichiometrically equivalent to the acid sample?

A student has a sample of the strong acid \(\text{HNO}_3\text{(aq)}\) represented in the particulate diagram. The four answer choices represent different samples of \(\text{Ba(OH)}_2\text{(aq)}\) using the same particulate scale. Assume that both solutes dissociate completely, water molecules are omitted, and the neutralization reaction goes to completion. Which particulate representation contains an amount of \(\text{Ba(OH)}_2\text{(aq)}\) that is stoichiometrically equivalent to the acid sample?

![Legend first, in the upper right corner: an open white circle represents \(\text{H}^{+}\text{(aq)}\), and a solid black triangle represents \(\text{NO}_3^{-}\text{(aq)}\). Draw one upright rectangular beaker outlined in black with a horizontal liquid level near the top. Within the liquid, place exactly four open white circles and exactly four solid black triangles. Arrange the eight particles in two staggered rows, with two particles of each shape in each row. Keep all particles separated and away from the beaker walls. Every particle icon represents the same amount of its species. Do not show water molecules, bonds, pairing between oppositely charged ions, or a precipitate. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787143338-g9dg81.jpg)
