6. Which of the following test tubes a) (5 Points) would have the fastest rate of reaction? Defend your answer.
b) (5 Points) would have the slowest rate of reaction? Defend your answer.
0.1 M
AgNO,
0.1 M
AgNO
1 M
AgNO.
Zinc
powder
Solid
zinc
Zinc

a. zinc because it is on top of them all in the reactive series so it reacts faster .

b. Ag because it is on the bottom of the reactive series and its reacts slow

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.
