Answer: Option (C) is the correct answer.

Explanation:

A covalent compound is formed by sharing of electrons between two chemically combining atoms.

A covalent bond will always form between non-metals.

Some properties of covalent compounds are as follows.

  • Covalent compounds are brittle in nature. This means they tend to break easily.
  • Covalent compounds have low melting and boiling point.
  • These compounds are unable to conduct heat and electricity.
  • Covalent compounds generally do not dissolve in water.

As covalent compounds have low melting and boiling point so, it is possible that they evaporate at room temperature.

Thus, we can conclude that sample C is a liquid that evaporates at room temperature, most likely to be a covalent compound.

What will happen to the efficiency of a bike after the gears have been cleaned and the chain has been oiled ?
seropon [69]

Well, figures for efficiency vary a lot, but according to Bicycling Science it’s lubrication that matters most – lubing a dry chain can add 5% to the efficiency.

More interestingly (and I hadn’t read this bit in the book before) it varys a lot depending on gear ratio – bottom gear (22-28) is 99% efficient, top gear (42-11) is 88%. That’s a big difference
