Answer:

The answer is E: I, II, and III

Step-by-step explanation:

The three major features of a well designed experiment are:

1. Replication: If an experiment cannot be replicated, then it is not a well-designed experiment. Replication is one of the major characteristics of a well designed experiment

2. Control: A well designed experiment must have a control. Control, in an experiment, can be referred to as the steps taken to curb the impact of extraneous variables

3. Randomization: Subjects are expected to be randomly assigned to different groups.

How much water should be added to 12mL of 11% alcohol solution to reduce the concentration to 6%

laila [671]

Answer:

We have 12 mL of 11% alcohol.

How much water do we add to make it a 6% solution?

We have 1.32 mL alcohol and 10.68 mL water

x is the water to add

(1.32) / (12 + x) = .06

1.32 = .72 + .06x

.6 = .06x

x = 10 mL
