Which statement explains the polarity of a water molecule?
timofeeve [1]

Answer:

D. The oxygen side is partially negative because electrons are pulled toward the oxygen side.

Explanation:

The water molecule is polar by the virtue of covalent bonds and the hydrogen bonds within and between its molecule.

The oxygen side is partially negative because the electrons are pulled toward the oxygen side.

Between oxygen and hydrogen that makes up the water molecule, oxygen is more electronegative.

An electronegative atom has more affinity for electrons. Since the electrons in the molecule of water is shared between hydrogen and oxygen, the more electronegative specie which is water draws the electron more to itself.

This leaves a net negative charge on the oxygen atom.

how many days does it take a team of drivers to drive a truck california and back to lansing if the drivers average 15m/s includ
malfutka [58]

4days and 12hours

Explanation:

Given parameters:

Average speed  = 15m/s

Distance = 1800 miles

Unknown:

Number of days = ?

Solution:

Speed is the rate of change of distance with time;

          Speed = \frac{distance}{time}

Since the unknown is number of days, it is a measure of time:

    Time = \frac{distance }{speed}

The distance from California to Lansing is 1800miles. The journey takes the truck drivers to and fro. It is a two way trip;

 Total distance = 1800 miles x 2 = 3600miles

We need to convert miles to meters since that is the unit we can conveniently work with;

            1 mile = 1609.34m

          3600 miles =  3600 x 1609.34

                              = 5793638m

Inputting the values in the equation:

          Time = \frac{ 5793638}{15} = 386242.53s

Now we need to convert to day;

In a day, = 60 x 60 x 24 = 86,400s

                 1 day = 86400s

 Therefore;

  The number of days = \frac{386242.53}{86400} = 4.47days

This implies that it will take them 4 days and approximately 12 hours.
