N-butyl mercaptan is the common name of a foul-smelling substance obtained from skunk fluid. it is a thiol of the type rx, where r is an n−butyl group and x is the functional group that characterizes a thiol. write the structural formula for this substance.

Butanethiol is chemically classified among the thiols, which are organic compounds with molecular formulas and structural formulas similar to alcohols, except that sulfur-containing sulfhydryl group (-SH) replaces the oxygen-containing hydroxyl group (-OH) in the molecule. Butanethiol's basic molecular formula is C4H9SH, and its structural formula is similar to that of the alcohol n-butanol. Butanethiol is prepared by the free radical catalyzed addition of hydrogen sulfide to 1-butene. Commercially, this is performed using ultraviolet light. Butanethiol is a thiol of low molecular weight, and it is highly flammable.

An object´s momentum increases with velocity

Explanation:

Mass in motion is a short phrase to describe the term momentum.

Momentum of a body explains the tendency of such an object to continue moving. It is expressed as the produce of mass and velocity of a body:

                Momentum = mv

The momentum of a body is directly proportional to its mass and velocity. Therefore, an object's momentum increases with both mass and velocity. The greater the momentum a body has, the greater the force it will exert on a body it hits.
