Even at low dilutions, hydrogen peroxide will decompose continuously into water and oxygen. This rate is very low when hydrogen peroxide is stored in approved materials and is kept free from contaminants. However, if oxygen pressure is not relieved, then high gas pressure may build up.

Because density of ice is less than that of water, that's why ice floats on the surface of water

Sanidhya Jadaun? 7 years, 1 month ago

Please see the structure of ice in ncert text. You will get to know that when ice is formed , many vacant spaces forms inside the structure of ice and when ice is put into water then water fills into this gaps and thus ice floats on water.

Atomic radius of alkali metals increases down the group and increases across period why?

Posted by Shravani Shinde 7 years, 1 month ago

CBSE > Class 11 > Chemistry

1 answers

Yogita Ingle 7 years, 1 month ago

On going down the atomic radius increases so ionisation energy decrease, this means that tendence of losing electron increases which implies increase in metallic character ( as electron affinity also decreases ). We know that oxides and hydroxides of metals are basic in nature. Thus basic character increases down the group.
The basic nature can also be explained by electro negativity concept and acid ionisation constant (Ka). As the electro negativity of the orbital which contains the lone pair increases acidic strength increase.

Ionic character refers to where the compound lies on a continuum between totally ionic and totally covalent.

Priya Dharshini ☺☺ 7 years, 1 month ago

the term "ionic bonding" is given when the ionic character is greater than the covalent character – that is, a bond in which a large electronegativity difference exists between the two atoms, causing the bonding to be more polar (ionic) than in covalent bonding where electrons are shared more equally

Shamsher Hassan 7 years, 1 month ago

Viscosity is that characteristics ot flowing by virtue of which it opposes the relative motion between adjacent layers of flowing fluid

Yogita Ingle 7 years, 1 month ago

Viscosity refers to the resistance to the flow of liquid arising as a result of the internal friction within the layers as they pass over other layer.
Viscosity arises due to the strong intermolecular forces between the molecules that holds them together and resist the passing of layers over other.
The layers of molecules of the flowing liquid that are in contact with the surface are stationary.
Increase in the distance between the two layers increases the velocity of the upper layer.
