Natasha and Reanna observe a large airplane in the troposphere. Which experimental setup below would best determine how changing

wind speeds might affect the airplane’s flight time to its destination?
The airplane's flight time is the test variable (independent variable), the wind speed is the outcome variable (dependent variable), and the airplane is the constant.

Answer:

i am pretty sure the answer is a

Explanation: because the airplane's flight time has to be the independent variable for it to affect the dependent variable that is the speed of how fast the airplane is going.

The discovery of the atomic nucleus, or perhaps better stated the development of theory of the nucleus, is credited to Ernest Ru
Greeley [361]

Answer:

Both of the studies said that the mass of the atom is centered in the nucleus, which is positive, and there are electrons (negative particles) orbiting it. So, Rutheford and Nagaoka discovered that the atom can be divisible and it has an empty space.

But, in the model of Nagaoka, the nucleus was huge, and for Rutherford, the nucleus was really small, and the mass was concentrated. By his experiment with the gold sheets, the theory was appropriated. That's why Rutherford is credited with the discovery of the nucleus. Nagaoka was incorrect in his suppositions.

In a common laboratory experiment in general chemistry students are asked to determine:_____.
Alex787 [66]
<h3>The <u>complete question</u> would be:</h3>

In a common laboratory experiment in general chemistry, students are asked to determine the relative amounts of benzoic acid and charcoal in a solid mixture. Benzoic acid is relatively soluble in hot water, but charcoal is not. Devise a method for separating the two components in the mixture.

<h3>The <u>solution</u> for that would be:</h3>

First you put the mixture in hot water and allow the benzoic acid to separate. Next funnel it and then see what's on the funnel paper. Lastly, heat the leftover water and see what's left after it evaporates.

<h3><u>What are laboratory experiments ?</u></h3>
  • Using controlled surroundings to test theories, researchers may develop laboratory experiments.
  • Laboratories are rooms or specially constructed facilities within buildings that are often found on college and university campuses and are utilized for academic research.
  • It's crucial to differentiate between experiments and other kinds of research investigations carried out in lab settings.
  • Even if a research study takes place in a lab, it is not always an experiment.
  • In order to evaluate causal conclusions regarding the links between independent and dependent variables, laboratory studies, like all genuine experimental designs, use procedures of random assignment of participants and control groups.

What are six traits of a good scientific observer
Ratling [72]
1. Curiosity-They love to learn                                                                                      2. Open-mindedness- he accepts criticisms fairly well 
3. Rationality- he does not believe in superstitions and think that everything has a scientific explanation 
4. Critical Mindedness & Correct Judgement- he does not easily jump to conclusions but tries to verify his results by (if possible) repeating the experiment 
5. Intellectual Honesty- does not alter his observations and writes the correct observations he has seen 
6. Objectivity-<span> he writes accurate results

2KClO3(s) =&gt; 2KCl(s) + 3O2(g) <br> is there an increase or decrease of entropy?
ValentinkaMS [17]

Answer:

Entropy increases

Explanation:

Entropy (S) is a measure of the degree of disorder.  For a given substance - say water - across phases the following is true ...

S(ice) < S(water) << S(steam)

For a chemical process, entropy changes can be related to increasing or decreasing molar volumes of gas from reactant side of equation to product side of equation. That is ...

if molar volumes of gas increase, then entropy increases, and

if molar volumes of gas decrease, then entropy decreases.

For the reaction                  2KClO₃(s) => 2KCl(s) + 3O₂(g)

molar volumes of gas =>       0Vm*            0Vm      3Vm

*molar volumes (Vm) apply only to gas phase substances. Solids and liquids do not have molar volume.

Since the reaction produces 3 molar volumes of O₂(g) product vs 0 molar volumes of reactant, then the reaction is showing an increase in molar volumes of gas phase substances and its entropy is therefore increasing.
