Hydrogen gas can be prepared by reaction of zinc metal with aqueous HCl:
kow [346]

Answer:

The volume of hydrogen gas generated by given reaction is 9.48 L

Explanation:

Firstly, we calculate the mole of Zinc added, n = 25.5 / 65 = 0.392 mol

With the same equivalent, the mole of generated hydrogen gas will be the same, at 0.392 mol.

Secondly, we get the equation

<em>P . V = n . R . T</em>

with P (pressure, atm), V (volume, litre), n (mole, mol), R (ideal gas constant, 0.082), T (temperature, Kelvin)

So we have to convert the given information to correct unit

P = 742 mmHg = 0.976 atm

T = 15 °C = 288 K

Hence we can calculate the generated volume by

V = n . R . T / P = 0.392 x 0.082 x 288 / 0.976 = 9.48 L

Calculate the pH of the buffer
77julia77 [94]

Answer:

Less than 7 so it is going to be acidic.
