Answer:

Yes, acetaminophen is conductive in water.

Explanation:

Have a nice day!

Acetaminophen is conductive in water and it is electrochemically active. It is used as an antipyretic drug.

Acetaminophen is an organic compound containing the amine functional group. One of the most popularly prescribed analgesic and antipyretic medications, acetaminophen (AC), is thought to be both effective and safe.

AC is not poisonous or harmful when used rationally, but an overdose or continued use may cause nephrotoxicity and severe hepatotoxicity. As a result, AC monitoring is crucial for drug safety.

Various conductometric measurements reported the fair conductivity shown by acetaminophen in water. The intermolecular interaction of acetaminophen in water make it conductive.

Answer:

Explanation:

In the scenario that is being described the control group would be the 50 men that have been given the placebo because they are the ones that should not have any effects from the placebo and that is by design. The manipulated variable is the new fat-burning pill because it is the one that the scientists can change and modify to try and achieve the desired results. Lastly, the responding variable are the 50 men who are given the new fat-burning pill because they are the ones that will be responding to the effects of the pill and providing the data needed by the scientists.

Ba(OH)2 is a strong base, so it conducts electricity well

Explanation:

The dissociation of a strong electrolyte is apparent by its reaction arrow, which only points toward products. In contrast, the reaction arrow of weak electrolytes points in both directions. The general form of the strong electrolyte equation is: Strong acids, strong bases, and ionic salts that are not weak acids or bases are strong electrolytes.

X     NH3 is a weak base

X     C12H22011 is neutral (not an acid or a base), therefore it a nonelectrolyte

X     CH3COOH is a weak acid and it also dissociates partially.

The substance which is a strong electrolyte is Ba(OH)₂.

Hence Option (B) is correct answer.

Strong electrolyte can be defined as the substance that completely dissociates in to ions.

Strong electrolyte (aq) → cation⁺ (aq) + anion⁻ (aq)

Now lets check all options one by one

Option (A): NH₃

NH₃ is a weak base. NH₃ does not completely ionize so it is a weak electrolyte.

Hence it is incorrect option.

Option (B): Ba(OH)₂

Ba(OH)₂ is a strong electrolyte because it dissociates completely in water.

Ba(OH)₂ (aq) → Ba⁺² (aq) + 2OH⁻ (aq)

Hence, it is correct option.

Option (C): C₁₂H₂₂O₁₁

C₁₂H₂₂O₁₁ is a non electrolyte that means it does not dissociate into ions.

Hence, it is incorrect option.

Option (D): CH₃COOH

CH₃COOH is a weak electrolyte due to the presence of lowest number of ions it does not dissociate. It's ionization is very less.

Hence, it is incorrect option.

Thus, from the above conclusion we can say that The substance which is a strong electrolyte is Ba(OH)₂.

Hence Option (B) is correct answer.

Answer:

A. cutting a substance into four pieces

Explanation:

The others include burning, reacting, and rust which make up a chemical change.

Cutting a substance into four pieces indicates a physical change. The correct option is A.

Even before to and after a physical change, the material implicated is unique architectural the same.

Physical changes include texture, shape, heat, and the beginning of a change in the state of matter. The texture of a substance influences how it feels.

A physical change is simply a change in appearance. The situation has not changed since the change.

Physical change can be seen in the use of cutting paper, melting butter, dissolving salt in water, and breaking glass.

Chemical reaction takes place when bonds among molecules or atoms are broken or formed.

This implies that one material with a specific set of properties is transformed into another substance with a different set of properties.

Thus, the correct option is A.

Answer:

Scientific theories are testable and make falsifiable predictions. They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific areas of inquiry (for example, electricity, chemistry, and astronomy).

A good theory in the theoretical sense is (1) consistent with empirical observations; is (2) precise, (3) parsimonious, (4) explanatorily broad, and (5) falsifiable; and (6) promotes scientific progress (among others; Table 1.1).

Answer:

a) [tex]BaF_{2}[/tex]

b) [tex]SnCl_{4}[/tex]

c) [tex]Cr_{2}O_{3}[/tex]

d) [tex]FeO[/tex]

e) [tex]Li_{3} P[/tex]

Explanation:

The charges of the ions have to be 0, so they balance.

a) [tex]Ba^{2+}[/tex] has the charge of +2 and [tex]F^{-}[/tex] has the charge of -1. So its [tex]0=(+2)+(-1)*2[/tex]. That means you need one [tex]Ba^{2+}[/tex] and two [tex]F^{-}[/tex] to balance the equation. -> [tex]BaF_{2}[/tex]

b) [tex]Sn^{4+}[/tex] has the charge of +4 and [tex]Cl^{-}[/tex] has the charge of -1. So its [tex]0=(+4)+(-1)*4[/tex]. That means you need one [tex]Sn^{4+}[/tex] and four [tex]Cl^{-}[/tex] to balance the equation. -> [tex]SnCl_{4}[/tex]

c) [tex]Cr^{3+}[/tex] has the charge of +3 and [tex]O^{2-}[/tex] has the charge of -2. So its [tex]0=(+3)*2+(-2)*3[/tex]. That means you need two [tex]Cr^{3+}[/tex] and three [tex]O^{2-}[/tex] to balance the equation. -> [tex]Cr_{2}O_{3}[/tex]

d) [tex]Fe^{2+}[/tex] has the charge of +2 and [tex]O^{2-}[/tex]has the charge of -2. So its [tex]0=(+2)+(-2)[/tex]. That means you need one [tex]Fe^{2+}[/tex] and one [tex]O^{2-}[/tex] to balance the equation. -> [tex]FeO[/tex]

e) [tex]Li^{+}[/tex] has the charge of +1 and [tex]P^{3-}[/tex]has the charge of -3. So its [tex]0=(+1)*3+(-3)[/tex]. That means you need three [tex]Li^{+}[/tex] and one [tex]P^{3-}[/tex] to balance the equation. -> [tex]Li_{3} P[/tex]
