If your in a city, go inside a building immediately. most buildings have lightening rod, so the lightening voltage won't hit on you.
if you're in an open area, don't go under a tree, or it'll hit you and the tree, even if it doesn't hit you, you still cannot take the impact by the exploding tree. leave the water or metal bicycle or stuff that conducts electricity.
'Every action has an equal but opposite reaction' They are equal, but opposite.
The silicon wafer contains 20.96 g of silicon.
The mole of a substance is related to its mass and molar mass by the following equation:
<h3>Mole = mass / molar mass ....... (1)</h3>
Making mass the subject of the above equation, we have
<h3>Mass = mole × molar mass ..... (2)</h3>
With the above formula (i.e equation 2), we can obtain the mass of silicon in the wafer as follow:
Mole silicon = 0.746 mole
Molar mass of silicon = 28.09 g/mol
<h3>Mass of silicon =? </h3>
Mass = mole × molar mass
Mass = 0.746 × 28.09
<h3>Mass of silicon = 20.96 g</h3>
Therefore, the mass of silicon in the wafer is 20.96 g
