A scientist designed an experiment to test the effect of temperature on bacterial growth. The independent variable in this experiment was temperature.

<h3>What is the bacterial growth?</h3>

The outcomes display that microbes have a better increase price at 20, 25 and 30°C and 30°C than at 3°C. In general, an boom in temperature will boom enzyme pastime. But if temperatures get too excessive, enzyme pastime will reduce, and the protein (the enzyme) will denature.

General, the better the temperature, the greater without problems microorganisms can develop as much as a sure point. Very excessive and coffee temperatures each impede the enzyme strategies microorganisms rely on to survive.

How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?
vaieri [72.5K]

Explanation:

The given data is as follows.

              M_{1} = 3 M,           V_{1} = ?

              M_{2} = 10 M,         V_{2} = 10.0 ml

Therefore, calculate the volume of given solution as follows.

              M_{1} \times V_{1} = M_{2} \times V_{2}

Now, putting the given values into the above formula as follows.

            M_{1} \times V_{1} = M_{2} \times V_{2}

            3 M \times V_{1} = 10 M \times 10.0 ml    

                   V_{1} = 33.3 ml

or,                             = 0.033 L        (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

           Molarity = \frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}

               3 M = \frac{mass}{40 g/mol \times 0.033 L}

              mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

Use the following study to answer the following question: A researcher applies varying amounts of fertilizer (0, 2, 4, 8, 10 uni
Ksenya-84 [330]
I believe the answer is the weight of each tomato.

This is because the weight of each tomato depends on the amount of fertilizer (the independent variable/the thing being changed) added to each plant.
