Answer: Option (b) is the correct answer.

Explanation:

When an atom shares electrons with another atom then it results in the formation of covalent bond.

Whereas when an atom transfer electrons from one atom to another then it results in the formation of ionic bond.

When nucleus of an atom splits then it represents nuclear fission reaction and energy is released during this process.

For example, ^{235}_{92}U \rightarrow ^{144}_{56}Ba + ^{89}_{36}Kr + 3n + 177 MeV

Therefore, we can conclude that out of the given options, the nucleus of an atom is split apart most likely release the greatest amount of energy.

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
