When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.
almond37 [142]

True

Explanation:

When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.

This very correct.

  • When electricity is used in a sustainable way, there is little of it consumed.
  • Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
  • Less coal and fuel would be used and power plants do not need to produce as much electricity.
  • Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
  • When these appliances are turned off, less energy is in demand and less will be produced.

Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 7.80 moles of magnesium perchlorate, Mg(ClO4)2.
Dmitry [639]
 The number of moles of moles of  Magnesium,chlorine and oxygen atoms in 7.80 moles of Mg(ClO4)2 is calculated as below

find the total number of each atom in Mg(ClO4)2

that is mg = 1 atom
        Cl =  1x2 = 2 atoms
        O  = 4  x2 = 8 atoms

then multiply 7.80 moles with total number of each atom , to get the number moles of each atom
that is

Mg = 7.80 x1= 7.80  moles
cl =   7.80  x2=15.6  moles
O =  7.80 x8= 62.4 moles
