Explanation

Ions and compounds are colorless is not a property of transition elements.

Transition elements often form colored compounds due to d-d electron transitions, while they also exhibit high melting points.

They are hard metals, and are good conductors of electricity.

Explanation

The solubility of sulfates of alkaline metals generally decreases down the group.

As you move down the group, the lattice energy of the sulfates increases.

This making them less soluble in water.

Explanation

The formula to calculate work (W) is:

W = F × d

Where:

F = force (in Newtons)

d = displacement (in meters)

Given:

F = 1 N (force)

d = 1 m (displacement)

W = 1 N × 1 m = 1 J

So, the work done is 1 Joule.

Explanation

In an endothermic reaction, the heat content of the products is more than that of the reactants.

This is because endothermic reactions absorb heat from their surroundings.

It leading to an increase in the enthalpy (heat content) of the products compared to the reactants.

Explanation

The chromosomal abnormality in Turner syndrome is represented by XO.

Individuals with Turner syndrome have a missing or partially missing X chromosome.

It leading to developmental issues in females.

Explanation

Full wave rectification is given by four diodes connected in bridge type arrangement.

This configuration allows both halves of the A.C. waveform to be used, producing a smoother and more efficient output compared to half-wave rectification.

Explanation

The correct option required for the maximum yield of ammonia by Haber’s process is high pressure, low temperature, continual removal of ammonia.

High pressure shifts the equilibrium towards ammonia production, while low temperature favors the exothermic reaction; continually removing ammonia drives the reaction further to the right, enhancing yield.

Explanation

The organelles only found at the seeding stage in oil seed plants are glyoxiosomes. They are specialized peroxisomes involved in the conversion of stored fats into sugars during seed germination.

Explanation

"A few words spoken in earnest will convince him."

جوش سے کہے گئے چند الفاظ اسے قائل کر لیں گے۔

This implies that a small number of sincere words will be enough to persuade him.

Explanation

A diode characteristic curve is a plot between voltage and current.

It shows the relationship between the applied voltage across the diode and the resulting current.

It indicating the diode's behavior in both forward and reverse bias.
