Question

naoh (aq) + hcl (aq) → nacl (aq) + h₂o (l)
in the chemical reaction above, which is in liquid state?
a nacl
b h₂o
c naoh
d hcl

Explanation:

Step1: Analyze the state symbols

In chemical equations, (aq) means aqueous (dissolved in water), (l) means liquid, (s) means solid, and (g) means gas.

Step2: Check each option

• Option a: NaCl is shown as (aq) (aqueous), not liquid.
• Option b: \(H_2O\) is shown as (l) (liquid).
• Option c: NaOH is shown as (aq) (aqueous), not liquid.
• Option d: HCl is shown as (aq) (aqueous), not liquid.

Answer:

B. \(H_2O\)
