Zinc reacts with hydrochloric acid according to the reaction equation Zn ( s ) + 2 HCl ( aq ) ⟶ ZnCl2 ( aq ) + H 2 ( g ) How many milliliters of 5.00 M HCl ( aq ) are required to react with 8.05 g Zn ( s )

The volume for the reaction is 49.2 mL

Explanation:

We define the reaction where 1 mol of solid Zn reacts with 2 moles of hydrochloric to produce zinc chloride and hydrogen

The equation is:

Zn (s) + 2 HCl (aq) ⟶ ZnCl₂ (aq) + H₂(g)

First of all, we convert the mass of Zn to moles → 8.05 g / 65.41 g/mol = 0.123 moles

Ratio is 1:2. Then 0.123 moles will need the double of moles of HCl to react. (0.123 . 2 ) = 0.246 moles

We do not know the volume, but we have the molarity of the acid.

Molarity = moles of solute / volume (L) of solution

Therefore, volume (L) of solution = moles of solute / Molarity

Volume (L) of solution = 0.246 moles / 5 mol/L = 0.0492 L

0.0492L = 49.2 mL

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
