Explain the impact that changing pressure has on a system in a state of dynamic equilibrium. What will happen when pressure on a reaction mixture at equilibrium and with fewer moles on the reactant side is increased?

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
