Answer: For F_{2} + H_{2} \rightarrow 2HF, F_{2} is the oxidizing agent and H_{2} is the reducing agent.

For 2Mg + O_{2} \rightarrow 2MgO, Mg is the reducing agent and O_{2} is the oxidizing agent.

Explanation:

An oxidizing agent is defined as the substance which tends to oxidize other substances by itself gaining electrons. As a result, there will occur a decrease in its oxidation state.

On the other hand, a substance which tends to reduce other substances by itself losing electrons is known as an reducing agent. There will occur an increase in oxidation state of a reducing agent.

For example, F_{2} + H_{2} \rightarrow 2HF

Oxidation: H_{2} \rightarrow 2H^{+} + 2e^{-}

Reduction: F + 1e^{-} \rightarrow F^{-}

Hence, here F_{2} is the oxidizing agent and H_{2} is the reducing agent.

Also,

     2Mg + O_{2} \rightarrow 2MgO

Oxidation: Mg \rightarrow Mg^{2+} + 2e^{-}

Reduction: O_{2} + 2e^{-} \rightarrow O

Hence, here Mg is the reducing agent and O_{2} is the oxidizing agent.

At what pH are the moles of acid and base equal?
mihalych1998 [28]

Answer:

7

Explanation:

(Note: for a strong acid and strong base titration the equivalence point is at a pH=7. This is because at this point you have equal moles of added base as acid in the original solution. Therefore at the equivalence point the solution has formed a neutral salt and the pH is 7).

Define Mole Concept give 3 Significance of Mole concept​
Alex Ar [27]

Answer:

The mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.
