A strong lightning bolt transfers an electric charge of about 31 C to Earth (or vice versa). How many electrons are transferred? Avogadro’s number is 6.022 × 1023 /mol, and the elemental charge is 1.602 × 10−19 C. If each water molecule donates one electron, how much water is ionized in the lightning? One mole of water has a mass of 18 g/mol. Answer in units of g.

is the no. of electrons

Explanation:

Given:

No. of electrons in the given amount of charge:

As we have charge on one electron

so,

is the no. of electrons

Then we require molecules.

Now the no. of moles in this many molecules:

where

Avogadro No.

So, the mass of water in the obtained moles:

where:

m = mass in gram

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
