Styles Researchers asked 131 college students to listen to a recording of a 20-minute introductory physics lecture. The students

Varvara68 [4.7K]

1. PUT YOUR NAME AT THE TOP OF THIS DOCUMENT: Debora Meinn

2. What is the independent variable in the study? The degree of beauty and attractiveness of the speakers. In a scientific study, the independent variable is the one that influences a result to happen, in this case, the beauty of the speakers was what influenced the degree of acceptance of the students, around the lecture.

3. What is the dependent variable in the study: The degree of acceptance of students in relation to the lecture. The dependent variable is one that needs to be influenced by the dependent variable in order to be able to evaluate a result. As we can see in the question above, the degree of beauty of the speakers influenced the degree of acceptance of the students in relation to the intelligence and competence of the speakers about the lecture.

4. How did the researchers "operationally define" attractiveness? They made this definition by evaluating the photos of the speakers, taken by other volunteers, who classified the photos as beautiful or ugly.

5. The results were said to be "statistically significant." What does that mean? It means that the acceptance of listeners to a lecture changes in relation to the beauty of the speakers.

6. Give one possible confounding variable in the study: a possible confounding variable would be the content of the lectures. Confounding variables are elements that can influence both the independent and the dependent variable. Thus, a complex or simple subject addressed as content of the lecture could influence both the perception of the beauty of the speakers and the acceptance of the lecture.

7. If the researchers stated that the results had generalizability ", what would that mean? It means that the results can be adopted as correct in any lectures.

8. In the context of the study, how would the researchers "debrief" the participants? They could ask whether they understood the lecture, whether the subject was spoken clearly, whether the speaker shows confidence, whether the speaker looks smart, whether the speaker looks healthy and whether the speaker dominates the subject matter.

9. Give one ethical consideration that would fit this study. (Refer to APA Ethical Guidelines on Blackboard): The confidentiality of volunteers' responses must be maintained. This is an ethical issue that must be respected in this study, according to APA's ethical guidelines.

10 How would another research check the reliability of this study? Reproducing it with the same variables. This should be done, because a reliable study must allow it to be repeated and will be considered true if the same results are observed.

11. If Hawthorne Effect affected the results of the study, what happened? If the Hawthorne Effect happened, the environment in which the volunteers were subjected interfered with the results. This is because the Hawthorne effect relates the physical conditions of an environment to the productivity of volunteers in relation to some factor. In this case, a more or less comfortable environment may have influenced the volunteers' acceptance of the lecture and the speakers.

What are some common acids and bases?

lutik1710 [3]

Answer:

1. Acetic acid (CH3COOH): vinegar, acetate.

Acetylsalicylic acid (HOOCC6H4OOCCH3): aspirin.

Ascorbic acid (H2C6H6O6): vitamin C.

Carbonic acid (H2CO3): soft drinks, seltzer water.

Citric acid (C6H8O7): citrus fruits, artificial flavorings.

Hydrochloric acid (HCl): stomach acid.

2. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

3. In the chemistry, acids and bases have been defined differently by three sets of theories. One is the Arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution.

4. pH < 7.

Sour taste (though you should never use this characteristic to identify an acid in the lab)

Reacts with a metal to form hydrogen gas.

Increases the H+ concentration in water.

Donates H+ ions.

Turns blue litmus indicator red.

5. Bitter taste (opposed to sour taste of acids)

Slimy, or soapy feel on fingers (Slippery)

Many bases react with acids and precipitate salts.

Strong bases may react violently with acids. ...

Bases turn red litmus paper blue.

Bases are substances that contain metal oxides or hydroxides.

6. The salt comes from weathering and volcanic activity. The ocean formed very early on in Earth history, as soon as water comes into contact with rock then weathering processes start – these leach (dissolve) the soluble elements preferentially out of the rock (sodium, calcium, magnesium, potassium etc).

7. <u>Magnesium Sulfate</u>, It is the product of the chemical reaction between magnesium hydroxide and sulfuric acid. In natural medicine, Epsom salts can be used as a laxative. A solution of the salts is used in many homes as a soak for foot aches, bruises and sprains. Some people enjoy using the chemical in their bath water.

8. Salt is white, odorless and it has a salty taste.

All potassium (K), ammonium (NH4+) and sodium (Na) salts are soluble in water (H2O).

Nitrites, nitrates, and bicarbonates can be dissolved in water.

All metallic oxides, metallic carbonates, hydroxides, phosphates, and sulphides are insoluble in water.

9. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
