Water is the universal solvent. it makes life possible on earth mainly due to its high specific heat capacity. water freezes a 0c and boils at 100c. water is a polar molecule. because of this, it exhibits the properties of cohesion and adhesion. water reacts with group 1 metals, sometimes explosively.
consider the paragraph above. what is one chemical property of water?
a) water is a polar molecule
b) water is the universal solvent.
c) water reacts with group 1 metals
d) water has a high specific heat capacity.

The answer to your question is: c) Water reacts with group 1 metals

Explanation:

A chemical property is a property that shows a change in the original molecule.

a) Water is a polar molecule  This is a physical property of water, it doesn't change the original composition of water. This option is incorrect.

b) Water is the universal solvent.  This is also a physical property of water, when water dissolves something it continues being water, then this answer is incorrect.

c) Water reacts with group 1 metals  Most of the reactions are chemical properties in this example when water reacts with a metal there is a change. This is the right option.

d) Water has a high specific heat capacity. This option is not correct, heat capacity is not a chemical property is a physical one.
