A student investigates the reaction between solid calcium carbonate and dilute hydrochloric acid at 25∘C25^\circ\text{C}25∘C and 1 atm1\text{ atm}1 atm pressure:

CaCO3(s)+2HCl(aq)→CaCl2(W)+H2O(X)+CO2(Y) \text{CaCO}_3\text{(s)} + 2\text{HCl}\text{(aq)} \rightarrow \text{CaCl}_2\text{(W)} + \text{H}_2\text{O}\text{(X)} + \text{CO}_2\text{(Y)} CaCO3​(s)+2HCl(aq)→CaCl2​(W)+H2​O(X)+CO2​(Y)

Which set of state symbols correctly identifies the physical states represented by W\text{W}W, X\text{X}X, and Y\text{Y}Y in this balanced chemical equation?

W=(s)\text{W} = \text{(s)}W=(s), X=(aq)\text{X} = \text{(aq)}X=(aq), Y=(g)\text{Y} = \text{(g)}Y=(g)

W=(aq)\text{W} = \text{(aq)}W=(aq), X=(l)\text{X} = \text{(l)}X=(l), Y=(g)\text{Y} = \text{(g)}Y=(g)

W=(aq)\text{W} = \text{(aq)}W=(aq), X=(aq)\text{X} = \text{(aq)}X=(aq), Y=(g)\text{Y} = \text{(g)}Y=(g)

W=(s)\text{W} = \text{(s)}W=(s), X=(l)\text{X} = \text{(l)}X=(l), Y=(g)\text{Y} = \text{(g)}Y=(g)
