Identity the step that is not part of the scientific method.

Chemistry
1 answer:
horrorfan [7]3 years ago
6 0

Options:

conduct an experiment

form a hypothesis

draw a conclusion

state the cause

Answer:

'<u>State the cause'</u> is not part of the scientific method.

Explanation:

The scientific method has three wholistic steps:

  • Test the hypothesis
  • Make observations from the experiment to the hypothesis
  • Draw a conclusion or prediction from the experimental results.

A cause is neither a scientific term nor is it part of the  processes of experimentation.

I hope this was helpful.

Radium-221 has a half-life of 30 sec. How long will it take for 96% of a sample to decay?
monitta
We can calculate how long the decay by using the half-life equation. It is expressed as:

A = Ao e^-kt

<span>where A is the amount left at t years, Ao is the initial concentration, and k is a constant.
</span><span>From the half-life data, we can calculate for k.
</span>
1/2(Ao) = Ao e^-k(30)
<span>k = 0.023
</span>
0.04Ao = Ao e^0.023(t)
<span>t = 140 sec</span>

Describe a method to separate the substances in a solution.
zhenek [66]

Answer:

By using different techniques.

Explanation:

For example: Chromatography involves solvent separation on a solid medium. Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes.

How many grams of NaHCO3 are needed to prepare 250 mL of 0.50 M<br> NaHCO3?
forsale [732]

Answer:

10.5g

Explanation:

First, let us calculate the number of mole of NaHCO3 present in the solution. This is illustrated below:

Volume = 250mL = 250/1000 = 0.25L

Molarity = 0.5M

Mole =?

Molarity = mole /Volume

Mole = Molarity x Volume

Mole = 0.5 x 0.25

Mole = 0.125 mole

Now, we shall be converting 0.125 mole of NaHCO3 to grams to obtain the desired result. This can be achieved by doing the following:

Molar Mass of NaHCO3 = 23 + 1 + 12 +(16x3) = 23 + 1 +12 +48 = 84g/mol

Number of mole of NaHCO3 = 0.125 mole

Mass of NaHCO3 =?

Mass = number of mole x molar Mass

Mass of NaHCO3 = 0.125 x 84

Mass of NaHCO3 = 10.5g

Therefore, 10.5g of NaHCO3 is needed.
