Answer: Option (d) is the correct answer.
Explanation:
An oxidizing agent is defined as the substance that itself gains an electron and helps in oxidation of another substance.
For example,
Here, is the oxidizing agent.
Also, a substance with more positive value of electrode potential will be the strongest oxidizing agent. Whereas a substance with more negative value of electrode potential will be the strongest reducing agent.
Therefore, out of the given options has the highest positive value of electrode potential so, is the strongest oxidizing agent.
Answer:
The incorrect statement is option B and D.
Explanation:
Carbohydrates are more generally is known as the sugars that are composed of the carbon, hydrogen and oxygen atoms. Monosaccharides are the single unit of carbohydrates while disaccharides are the sugars that contain two molecules of the sugar and similarly saccharides with multiple sugars are called polysaccharides. The general chemical formula of the carbohydrates Cn(H2O)n, however the complex sugars does not follow this formula. Amino sugars are contains NH2 in their formula so carbohydrates not necessarily contains only H, O, AND C always.
Thus, the incorrect answer is - option B and D.
Answer:
Either the first one or the third one.
Explanation:
Using process of elimination: knowing that the controlled variable is something the conductor is able to control and stays the same throughout; the amount of water is the same, but it also states that temperature is not the same throughout. This cancels out B because the amount of sugar dissolved varies and doesn’t stay the same. D fits the same criteria as well.
so now we are left with A and C.
An independent variable is something that can be by itself and doesn’t depend on anything else. Sugar is NOT independent, as it dissolves DEPENDING on the amount of liquid. So we can already rule out that sugar is a dependent variable. Both A and C have those choices though, so now we are with the control group and the independent variable.
Think about it, which is the independent variable? Water amount doesn’t depend on anything, while the temperature depends on the room. So the answer is most likely A.
Hope this helps, don’t stress about homework. Happy Holidays!
