Explain how the scientific method helps scientists.
Lapatulllka [165]

As scientists work hard for the results, they may get biased and may sometimes come up with an answer that is based on that. In order to avoid such circumstances, scientific method is put into practice.

Explanation:

  • Personal preferences can some times affect a scientific answer. That is not desirable as the experiments will be repeated by different individuals and the same results should be obtained.
  • That leads to the importance of documentation of systemic observation, formation of hypothesis and the experimentation to confirm the results, which is the scientific way of coming up with the answer to a scientific problem.
  • Scientific methods thus helps in bringing more credibility to findings of the scientists and can be repeated by others to obtain the same results.

Calculate the volume in milliliters of a 0.420mol / L barlum chlorate solution that contains 25.0 g of barium chlorate (Ba(ClO 3
Pachacha [2.7K]

<u>Answer:</u> The volume of barium chlorate is 195.65 mL

<u>Explanation:</u>

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

Given mass of barium chlorate = 25.0 g

Molar mass of barium chlorate = 304.23 g/mol

Molarity of solution = 0.420 mol/L

Volume of solution = ?

Putting values in above equation, we get:

0.420mol/L=\frac{25.0\times 1000}{304.23\times V}\\\\V=\frac{25.0\times 1000}{304.23\times 0.420}=195.65mL

Hence, the volume of barium chlorate is 195.65 mL

Referencing the reasoning you used from #1, explain the difference between objects that feel hot and those that
dezoksy [38]

Answer:

The temperature of the cold water is lower than the warm one. So, when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is.
