1. To make a peanut butter and jelly sandwich, you need 2 slices of bread, 2 tablespoons of peanut
butter, and 1 tablespoon of jelly. You have 6 slices of bread, 12 tablespoons of peanut butter,
and 4 tablespoons of jelly. How many whole sandwiches can you make, and what is the limiting
ingredient?
a. 4, jelly
b. 6, peanut butter
c. 3, bread
d. 4, bread
e. 3, peanut butter

3, bread

Explanation:

bread is the limiting reagent because it is what you have the least of recipe wise. you would be able to make 4 sandwiches if there were 8 slices of bread, then the limiting reagent would be both the bread, and jelly, leaving the bread as the excess reagent.

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.
