a) The metal is in the solid state (s).b) The acid is dissolved in water (aq).c) The hydrogen is in the gas state (g).
Explanation
## Step1: The question asks us to identify the state of the metal, acid, and hydrogen in a general reaction where an acid reacts with a metal to produce a salt and hydrogen. ## Step2: In general, the metal used in such reactions is in solid state. This is because metals are typically solid at room temperature and are used in their solid form in these reactions.## Step3: The acid, on the other hand, is typically dissolved in water (aqueous). This is because acids are often too dangerous or reactive to use in their pure form, so they are diluted in water to make them safer and easier to handle.## Step4: Finally, the hydrogen produced in these reactions is typically in the gaseous state. This is because hydrogen is a gas at room temperature and pressure, and it is released as a gas when an acid reacts with a metal.
