8 0

The question is incomplete, the complete question is; During a conference presentation, a scientist described the materials that she used and how she performed her experiments.

Which best explains why a scientist would share these details in a conference?

It tells the audience if the results support or contradict the hypothesis.

It tells the peers if the study is supported by mathematical models.

It informs the peers if the results are supported by other scientists.

It informs the audience if the study included controlled tests.

Answer:

It informs the audience if the study included controlled tests.

Explanation:

Usually, scientific conferences involve presentation of papers by scientists. These paper presentations are actually the sharing of details of the scientific research carried out by other scientists.

Presenting the materials and methods section of the a research project to a scientific conference informs the audience if the study included controlled tests.

The inclusion of controlled tests in a scientific study enhances the validity of the results obtained in the study.

What is the concentration of a potassium iodate solution after you complete the following porcedure? Pipette 10 mL of a 0.31 M p

zubka84 [21]

Given:

Initial concentration of potassium iodate (KIO3) M1 = 0.31 M

Initial volume of KIO3 (stock solution) V1 = 10 ml

Final volume of KIO3 V2 = 100 ml

To determine:

The final concentration of KIO3 i.e. M2

Explanation:

Use the relation-

M1V1 = M2V2

M2 = M1V1/V2 = 0.31 M * 10 ml/100 ml = 0.031 M

Ans: The concentration of KIO3 after dilution is 0.031 M

What is the best conclusion according to the energy diagram of the chemical reaction?

Mariulka [41]

"The reaction will absorb energy" is the best conclusion according to the energy diagram of the chemical reaction.

Option: B

Explanation:

The chemical bonds in the reactions are broken and formed as per process and contributed by three major steps: reactants, transition phase and product formation. Here transition phase is in equilibrium stage drived by activation energy, where bond is partially formed and partially broken, located at higher energy level then the starters.

The reactant's energy level is less relative to the products as seen in the endothermic reactions' energy diagram, which depicts that the products are less balanced than reactants. Here when the reaction is forced to the forward direction, then it direct towards the more unbalance entities. As energy is absorbed in the endothermic reaction from surrounding, thus the enthalpy change (ΔH) for the reaction is positive.
