Which part of experimental design is most important to a scientist when replicating an experiment? Having exactly the same data
yarga [219]

Answer:

The answer to your question is below:

Explanation:

Having exactly the same data as the previous experiment I think that having the same data as the previous experiment is extremely important but not the most important, for me is the second most important.

Using the same procedure and variables as the previous experiment For me, this is the most importan thing when a scientist is designing an experiment, because if he or she follow exactly the same procedure and variables, then the results will be very close.

Conducting an experiment similar to the previous experiment  This characteristic is important but not the most important.

Using the same laboratory that was used in the previous experiment It is not important the laboratory, if the procedure and variables are the same, your experiment must give the same results in whatever laboratory.

0.225L solution of H2CO3 is neutralized by 0.0880L of a 1.22 M Fe(OH)3 solution. What
ikadub [295]

Answer:

0.716

Explanation:

First, write the balanced equation:

3 H2CO3 + 2 Fe(OH)3 ----> Fe2(CO3)3 + 6 H2O

Second, go from the molarity of H2CO3 to liters of Fe(OH)3

(Pull mole ratio from balanced equation)

1.22/1L  x  0.0880/1  x  3molH2CO3/2molFe(OH)3 x 1/0.225L

Use calculator, and you end up with 0.7157333

Round to 0.716

Express 0.0000046 in scientific<br> notation.<br> [?]x10
aivan3 [116]

Answer:

4.6 x 10⁻⁶

Explanation:

In scientific notation, the number should be written in between 1 - 10 and multiplied by 10 raised to a power.

In this case, the decimal place should be placed in-between the 4 and the 6. To do this, you must move the decimal place 6 digits to the right. When you move the decimal place to the right, the 10 should be raised to a negative number.

As such, 0.0000046 in scientific notation is 4.6 x 10⁻⁶.
