Water and hydrogen peroxide are different compounds although they have the same kind of atoms. The molecular formula of water is H2O (two atoms of oxygen chemically bonded to one atom of oxygen). The molecular formula of hydrogen peroxide is H2O2, (each atom of oxygen is chemical bonded to one atom of H and other atom of O). So,<span> the presence of different chemical bonds leads to different products with different chemical properties.</span><span />
Answer:
Condensation
Explanation:
An exothermic process is one in which heat is lost. Condensation is a change of state from gas to liquid. Thus is loses heat.

<u>Answer:</u> The volume of bone for given sample is 
<u>Explanation:</u>
To calculate volume of a substance, we use the equation:
Density of bone = 
(Conversion factor: 1 g = 1000 mg)
Mass of bone = 25 g
Putting values in above equation, we get:
Hence, the volume of bone for given sample is
