Answer: Option (c) is the correct answer.

Explanation:

An alkene molecule has a double bond whereas an alkyne molecule has a triple bond.

Properties of alkenes and alkynes are as follows.

  • Both are insoluble in water.
  • Their pH is less than 7.
  • Boiling point increases with increase in carbon atoms or chain length.
  • Their densities are less than the density of water.

Thus, we can conclude that out of the given options, their boiling points tend to increase with chain length is a property of both alkenes and alkynes.

Mercury has a specific gravity of 13.6. how many milliliters of mercury have a mass of 0.35 kg
SashulF [63]

The formula for specific gravity is:

Specific gravity = \frac{\rho _{substance}}{\rho _{water}}

where \rho _{substance} is the density of the substance and \rho _{water} is the density of water.

The density of water, \rho _{water} = 1 g/mL

Substituting the values in above formula we get,

13.6 = \frac{\rho _{substance}}{1}

\rho _{substance} = 13.6 g/mL

The formula of density is:

density = \frac{mass}{volume}

The density of mercury is 13.6 g/mL

The mass of mercury is 0.35 kg = 0.35 kg \times 1000 \frac{g}{kg} = 350 g

Substituting the values in density formula:

13.6 g/mL = \frac{350 g}{volume}

volume = \frac{350 g}{13.6 g/mL} = 25.73 mL
