moles of Zn?

Respuesta :

Neetoo

Answer:

To react with 0.5 moles of zinc 1 mole of hydrochloric acid is required

Explanation:

Given data:

Number of moles of HCl = ?

Number of moles of Zn = 0.50 mol

Chemical equation:

Zn + 2HCl  → H₂ + ZnCl₂

Now we will compare the moles of zinc and HCl.

                       Zn       :        HCl

                         1        :            2

                       0.50   :         2×0.5 = 1 mol

So, to react with 0.5 moles of zinc 1 mole of hydrochloric acid is required.

Given the following equation; Zn + 2HCI → H2 + ZnCl2, 1 moles of HCl are needed to react with 0.50 moles of Zn.

HOW TO CALCULATE NUMBER OF MOLES?

The number of moles required to react with a substance can be calculated as follows:

Given the following equation;

Zn + 2HCI → H2 + ZnCl2

According to the above balanced equation, 1 mole of Zinc reacts with 2 moles of HCl.

If 0.5 moles of Zn reacts, 0.5 × 2/1 = 1 mole of HCl will react.

Therefore, given the following equation; Zn + 2HCI → H2 + ZnCl2, 1 moles of HCl are needed to react with 0.50 moles of Zn.
