<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
Temperature? Magma at different temps has different densities, less dense magmas rise to the top
Cyclohex<u>ene</u> is a cyclic, six-membered hydrocarbon that contains one double bond. The types of reactions that can occur in cyclohexene would be those that are typical with alkenes generally.
The pi-bonded electrons in the double bond are nucleophilic. So, electrophilic addition reactions could occur with cyclohexene. For example,
cyclohexene + HBr → bromocyclohexane
cyclohexene + H2O/H+ → cyclohexanol
cyclohexene + Br2 → <em>trans-</em>1,2-dibromocyclohexane (racemic)
The latter is a common test for alkenes where one adds bromine to a sample to see if there is decolorization, which would indicate the presence of nucleophilic pi bonds. Bromine, which is dark reddish-brown, will become clear as it reacts with an alkene to form a colorless haloalkane.
Cyclohexene can also be converted to the fully saturated cyclohexane by hydrogenation: cyclohexene + H2/Pd → cyclohexane.
