Which of these did your answer include?
Each hydrogen atom is bonded to the oxygen atom with a single bond.
The oxygen atom has two lone pairs.
The molecule is bent.
Oxygen is more electronegative than hydrogen.
Each O-H bond is polar.
The molecule is asymmetrical.
The asymmetry and the polar bonds produce an overall molecular dipole.
The oxygen atom has a partial negative charge, and the hydrogen atoms have a partial positive
charge.
DONE
Intro

i) Each Hydrogen atom is bonded to the oxygen atom with a single bond.

ii) The oxygen atom has two lone pairs.

iii) The molecule is bent.

iv) Oxygen is more electronegative than hydrogen.

v) Each O-H bond is polar.

vi) The oxygen atom has partial negative charge, and the hydrogen atoms have a partial positive charge.

NOTE: Above given points are correct and described by keeping in view the molecule of water.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
