which materials are included in the hydrosphere that are not in liquid form A. ice caps B. lakes and rivers C. rainforest and lakes D. rocks and minerals

The correct answer is option A, that is, ice caps.

Explanation:

The part of the planet Earth covered by water or ice is known as the hydrosphere. It comprises lakes, oceans, rivers, polar ice caps, and glaciers. The polar ice caps and glaciers are the only elements of solid found in the hydrosphere.  

The other options, that is, lakes and rivers are also a part of hydrosphere but they are in liquid form. While rainforest and rocks and minerals are the parts of the lithosphere, not hydrosphere.  

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

i think its 5049.

i hope this !
