Answer: D
Explanation:
A reducing agent is a species that reduces other compounds, and is thereby oxidized. The whole compound becomes the reducing agent. In other words, of a compound is oxidized, then they are the reducing agent. On the other hand, if the compound is reduced, it is an ozidizing agent.
Since we have established that a reducing agent is the compound being oxidized, we know that A is not our answer. An oxidized compound is losing electrons. Choice A states exactly this.
For B, this is true as we have established this already.
C is also correct. Since a reducing agent loses electrons, it becomes more positive. This makes the oxidation number increase.
D would be our correct answer. It is actually a good oxidizing agent is a metal in a high oxidation state, such as Mn⁷⁺.

Answer:
4.22 mol H₂O
Explanation:
Step 1: Write the equation for the synthesis of water
2 H₂ + O₂ ⇒ 2 H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to H₂O is 1:2.
Step 3: Calculate the moles of water produced from 2.11 moles of oxygen
We will use the previously established molar ratio.
2.11 mol O₂ × 2 mol H₂O/1 mol O₂ = 4.22 mol H₂O
Answer: The mass of 405 ml of cresol is 415 grams
Explanation:
Density is defined as the mass contained per unit volume.

Given : Density of cresol = 1024 g/L
Volume of cresol = 405 ml = 0.405 L ( 1L=1000ml)
Putting in the values we get:


Thus mass of 405 ml of cresol is 415 grams
