You are given a test tube containing 10 mL of a solution with 8.4 × 107 cells/mL. You are to produce a solution that contains less than 100 cells/mL. What dilutions must you perform in order to arrive at the desired result?

(1). 1 ml of original solution to 99 ml of water = 8.4 ×

(2). 1 ml of second solution to 99 ml of water = 8.4 ×

(3). 1 ml of third solution to 99 ml of water = 84  

Explanation:

Volume of solution = 10 ml

We should perform the following dilutions.

(1). 1 ml of original solution to 99 ml of water = 8.4 ×

(2). 1 ml of second solution to 99 ml of water = 8.4 ×

(3). 1 ml of third solution to 99 ml of water = 84  

These are the three dilutions we have to perform.

false

because it does not have the potential to be entirely used up

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
