Explanation

Adding more SO₂ – This would increase the yield by shifting the equilibrium toward the product (Le Chatelier's principle).

Explanation

A gas behaves non-ideally at low temperature and high pressure. 

At low temperatures, molecules have less kinetic energy,

Meaning they move more slowly and are more likely to experience intermolecular forces,

They cause them to deviate from ideal behavior.

High pressure also contributes to non-ideal behavior

Because the molecules are closer together, leading to increased interactions. 

Explanation

According to Graham’s Law of Diffusion, gases with lower molar mass diffuse faster.

Molar masses:

- H₂ = 2 g/mol (lowest)

- He = 4 g/mol  

- N₂ = 28 g/mol  

- CO₂ = 44 g/mol  

Since H₂ has the smallest molar mass, it will diffuse the fastest and thus escape in the least time. 

Explanation

The velocity of an electron is maximum in 1st shell

because according to Bohr's model

So we have velocity of electron = 2.188 ×10^6 m/s.

By calculation, we gained velocity= 1.094×10^6 m/s.

So it is determined that the velocity is decreased as we move from lower to higher shell

Explanation

If the maximum value of the principal quantum number (n) for an atom is 4, the total number of electrons in that atom is 32.

This is because the maximum number of electrons in a shell is given by 2n², and for n=4, this calculation results in 2 * 4² = 32. 

Explanation

 One gram atom of any element refers to one mole of its atoms.

- The molar mass of chlorine (Cl) is approximately 35.5 g, so:

  - One gram atom of chlorine = 1 mole of Cl atoms = 35.5 g, not 71 g (which is for Cl₂ molecules).

Explanation

The atomic mass of sodium is 23 g/mol.  

- This means 1 mole (6.022 × 10²³ atoms) of sodium weighs 23 grams.  

- So, the mass of one atom of sodium is:

= 23 g / Nₐ  

= 23 / (6.022 × 10²³) grams

So the correct option is: 23 / Nₐ g.

Explanation

Limestone is a Sedimentary Rock, Stratified Rock, Aqueous Rock.

Limestone consists of calcium carbonate,

Which has the chemical formula CaCO3.

Calcium carbonate is a chemical compound

It is a common substance found in rocks as the minerals calcite

Explanation

Explanation

A gas being cooled is a system where entropy is decreasing. 

When a gas is cooled, its molecules slow down and become more ordered, leading to a decrease in entropy.
